  • GridView does not display correcty sorted Data when i click column

    - by user329419
    Date column does not display in sorted in GridView using vb.net. In sql server the select query is returning records in sorted manner or in order by. But for some reason GridView does not display properly. it goes to an event preRenderComplete then it binds automatically Protected Sub Page_PreRenderComplete(ByVal sender As Object, ByVal e As

  • asp.net gridview bind dateformat not working with update

    - by Brabbeldas
    I have a GridView with a TemplateField column which shows a DateTime from a DataSource. <Columns> <asp:CommandField ShowEditButton="True" /> <asp:TemplateField HeaderText="Start Date"> <EditItemTemplate> <asp:TextBox ID="txtDateStart" runat="server" Text='<%# Bind("dtDateStart", "{0:dd/MM/yyyy}") %>'</asp:TextBox> </EditItemTemplate> <ItemTemplate> <asp:Label ID="Label1" runat="server" Text='<%# Bind("dtDateStart", "{0:dd/MM/yyyy}") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> </Columns> Displaying the date in the correct format works as it should. Note that the format starts with DAY followed by MONTH. When I switch to edit mode, change the date in the TextBox to '31-01-2013' and press the GridView's update-link i get an error: Cannot convert value of parameter 'dtDateStart' from 'System.String' to 'System.DateTime' The error is generated by the GridView not my own code. It happens before the UpdateMethod of my DataSource is called. When i type '01-31-2012' the data is processed correctly and the value is updated into the database. Somehow when the date is displayed it uses format dd-MM-yyyy (just as I need it to) But when it reads the new value form the TextBox it uses MM-dd-yyyy Can somebody please help me?

  • How to configure a GridView CommandField to trigger Full Page Update in UpdatePanel

    - by Frinavale
    I have 2 user controls on my page. One is used for searching, and the other is used for editing (along with a few other things). The user control that provides the search functionality uses a GridView to display the search results. This GridView has a CommandField used for editing (showEditButton="true"). I would like to place the GridView into an UpdatePanel so that paging through the search results will be smooth. The thing is that when the user clicks the Edit Link (the CommandField) I need to preform a full page postback so that the search user control can be hidden and the edit user control can be displayed. Edit: the reason I need to do a full page postback is because the edit user control is outside of the UpdatePanel that my GridView is in. It is not only outside the UpdatePanel, but it's in a completely different user control. I have no idea how to add the CommandField as a full page postback trigger to the UpdatePanel. The PostBackTrigger (which is used to indicate the controls cause a full page postback) takes a ControlID as a parameter; however the CommandButton does not have an ID...and you can see why I'm having a problem with this. Update on what else I've tried to solve the problem: I took a new approach to solving the problem. In my new approach, I used a TemplateField instead of a CommandField. I placed a LinkButton control in the TemplateField and gave it a name. During the GridView's RowDataBound event I retrieved the LinkButton control and added it to the UpdatePanel's Triggers. This is the ASP Markup for the UpdatePanel and the GridView <asp:UpdatePanel ID="SearchResultsUpdateSection" runat="server"> <ContentTemplate> <asp:GridView ID="SearchResultsGrid" runat="server" AllowPaging="true" AutoGenerateColumns="false"> <Columns> <asp:TemplateField> <HeaderTemplate></HeaderTemplate> <ItemTemplate> <asp:LinkButton ID="Edit" runat="server" Text="Edit"></asp:LinkButton> </ItemTemplate> </asp:TemplateField> <asp:BoundField ...... </Columns> </asp:GridView> </ContentTemplate> </asp:UpdatePanel> In my VB.NET code. I implemented a function that handles the GridView's RowDataBound event. In this method I find the LinkButton for the row being bound to, create a PostBackTrigger for the LinkButton, and add it to the UpdatePanel's Triggers. This means that a PostBackTrigger is created for every "edit" LinkButton in the GridView Edit: this did not create a PostBackTrigger for Every "edit" LinkButton because the ID is the same for all LinkButtons in the GridView. Private Sub SearchResultsGrid_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles SearchResultsGrod.RowDataBound If e.Row.RowType = DataControlRowType.Header Then ''I am doing stuff here that does not pertain to the problem Else Dim editLink As LinkButton = CType(e.Row.FindControl("Edit"), LinkButton) If editLink IsNot Nothing Then Dim fullPageTrigger As New PostBackTrigger fullPageTrigger.ControlID = editLink.ID SearchResultsUpdateSection.Triggers.Add(fullPageTrigger) End If End If End Sub And instead of handling the GridView's RowEditing event for editing purposes i use the RowCommand instead. Private Sub SearchResultsGrid_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles SearchResultsGrid.RowCommand RaiseEvent EditRecord(Me, New EventArgs()) End Sub This new approach didn't work at all because all of the LinkButtons in the GridView have the same ID. After reading the MSDN article on the UpdatePanel.Triggers Property I have the impression that Triggers can only be defined declaratively. This would mean that anything I did in the VB code wouldn't work. Any advise would be greatly appreciated. Thanks, -Frinny

  • Editing a Gridview row with drop-down lists gets too wide - how can I use popup panels instead?

    - by David
    I have a series of GridViews in a Tab Panel - databound to a generic List of Business Objects. The columns in the Gridview are all similar to the following: <asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName"> <ItemTemplate> <asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:DropDownList ID="ddlCompany" runat="server"></asp:DropDownList> </EditItemTemplate> </asp:TemplateField> The GridView generates the "Edit" link at the beginning of the row, all the events fire ok. The problem is that the data is getting long. When in 'display mode', it's fine because the GridView control is smart enough to break some text into multiple lines (in particular Project, Title and Worker names can get pretty long). The problem come in editing mode. Drop-down lists DON'T break entries into multiple lines (for obvious reasons). Going into Edit ode on a row in the Gridview can make the Griview expand horizontally to twice the screen size (blowing through the width limits in the Master page and CSS but that's only a related problem). What I need is something like the ModalPopup - but trying to tie it to an ID in an EditItemTemplate gives me errors when the page renders (because the 'ddlXXXX' doesn't exist at the time). In addition I don't know how to dynamically populate the panel so that I can get a response from it (like the ID of the Company they selected). I'm also trying to avoid javascript and would like this to be a 'pure' aspx/code-behind solution (for simplicity's sake among others). All the examples I find are of Modal Popups with the panels pre-defined. Even if it (the popup panel) were something like a list of checkboxes, it could be databound to the SortedList I have ready to go and an OK/Cancel button combination to accept or ignore things. I'm just not sure of what goes where. I'm open to suggestions. Thanks in advance. EDIT: Final solution looks as follows: <asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName"> <ItemTemplate> <asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:LinkButton ID="lnkCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:LinkButton> <asp:Panel ID="pnlCompany" runat="server" style="display:none"> <div> <asp:DropDownList ID="ddlCompany" runat="server" ></asp:DropDownList> <br/> <asp:ImageButton ID="btnOKCo" runat="server" ImageUrl="~/Images/greencheck.gif" OnCommand="PopupButton_Command" CommandName="SelectCO" /> <asp:ImageButton ID="btnCxlCo" runat="server" ImageUrl="~/Images/RedX.gif" /> </div> </asp:Panel> <cc1:ModalPopupExtender ID="mpeCompany" runat="server" TargetControlID="lnkCompany" PopupControlID="pnlCompany" BackgroundCssClass="modalBackground" CancelControlID="btnCxlCo" DropShadow="true" PopupDragHandleControlID="pnlCompany" /> </EditItemTemplate> </asp:TemplateField> And in the code-behind, lstIDLabor is the generic List of data lines (of which Company is one of the properties that is also a business object) that is bound to the GridView: Sub PopupButton_Command(ByVal sender As Object, ByVal e As CommandEventArgs) Dim intRow As Integer Dim intVal As Integer RestoreFromSessionVariables() Select Case e.CommandName Case "SelectCO" intRow = grdIDCostLabor.EditIndex Dim ddlCo As DropDownList = CType(grdIDCost.Rows(intRow).FindControl("ddlCompany"), DropDownList) intVal = ddlCo.SelectedValue lstIDLabor(intRow).CompanyID = intVal lstIDLabor(intRow).Company = Company.Read(intVal) Case Else ' End Select MakeSessionVariables() BindGrids() End Sub

  • Custom Paging for GridView in an UpdatePanel not firing PageIndexChanging event

    - by JeffCren
    I have a GridView that uses custom paging inside an UpdatePanel (so that the paging and sorting of the gridview don't cause postback). The sorting works fine, but the paging doesn't. The PageIndexChanging event is never called. This is the aspx code: <asp:UpdatePanel runat="server" ID="upSearchResults" ChildrenAsTriggers="true" UpdateMode="Always"> <ContentTemplate> <asp:GridView ID="gvSearchResults" runat="server" AllowSorting="true" AutoGenerateColumns="false" AllowPaging="true" PageSize="10" OnDataBound="gvSearchResults_DataBound" OnRowDataBound ="gvSearchResults_RowDataBound" OnSorting="gvSearchResults_Sorting" OnPageIndexChanging="gvSearchResults_PageIndexChanging" Width="100%" EnableSortingAndPagingCallbacks="false"> <Columns> <asp:TemplateField HeaderText="Select" HeaderStyle-HorizontalAlign="Center"> <ItemTemplate> <asp:HyperLink ID="lnkAdd" runat="server">Add</asp:HyperLink> <asp:HiddenField ID="hfPersonId" runat="server" Value='<%# Eval("Id") %>'/> </ItemTemplate> </asp:TemplateField> <asp:BoundField HeaderText="First Name" DataField="FirstName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" SortExpression="FirstName" /> <asp:BoundField HeaderText="Last Name" DataField="LastName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" SortExpression="LastName" /> <asp:TemplateField HeaderText="Phone Number" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" > <ItemTemplate> <asp:Label ID="lblPhone" runat="server" Text="" /> </ItemTemplate> </asp:TemplateField> </Columns> <PagerTemplate> <table width="100%" class="pager"> <tr> <td> </td> </tr> </table> </PagerTemplate> </asp:GridView> <div class="btnContainer"> <div class="btn btn-height_small btn-style_dominant"> <asp:LinkButton ID="lbtNewRecord" runat="server" OnClick="lbtNewRecord_Click"><span>Create New Record</span></asp:LinkButton> </div> <div class="btn btn-height_small btn-style_subtle"> <a onclick="openParticipantModal();"><span>Cancel</span></a> </div> </div> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="gvSearchResults" EventName="PageIndexChanging" /> <asp:AsyncPostBackTrigger ControlID="gvSearchResults" EventName="Sorting" /> </Triggers> </asp:UpdatePanel> In the code behind I have a SetPaging method that is called on the GridView OnDataBound event: private void SetPaging(GridView gv) { GridViewRow row = gv.BottomPagerRow; var place = row.Cells[0]; var first = new LinkButton(); first.CommandName = "Page"; first.CommandArgument = "First"; first.Text = "First"; first.ToolTip = "First Page"; if (place != null) place.Controls.Add(first); var lbl = new Label(); lbl.Text = " "; if (place != null) place.Controls.Add(lbl); var prev = new LinkButton(); prev.CommandName = "Page"; prev.CommandArgument = "Prev"; prev.Text = "Prev"; prev.ToolTip = "Previous Page"; if (place != null) place.Controls.Add(prev); var lbl2 = new Label(); lbl2.Text = " "; if (place != null) place.Controls.Add(lbl2); for (int i = 1; i <= gv.PageCount; i++) { var btn = new LinkButton(); btn.CommandName = "Page"; btn.CommandArgument = i.ToString(); if (i == gv.PageIndex + 1) { btn.BackColor = Color.Gray; } btn.Text = i.ToString(); btn.ToolTip = "Page " + i.ToString(); if (place != null) place.Controls.Add(btn); var lbl3 = new Label(); lbl3.Text = " "; if (place != null) place.Controls.Add(lbl3); } var next = new LinkButton(); next.CommandName = "Page"; next.CommandArgument = "Next"; next.Text = "Next"; next.ToolTip = "Next Page"; if (place != null) place.Controls.Add(next); var lbl4 = new Label(); lbl4.Text = " "; if (place != null) place.Controls.Add(lbl4); var last = new LinkButton(); last.CommandName = "Page"; last.CommandArgument = "Last"; last.Text = "Last"; last.ToolTip = "Last Page"; if (place != null) place.Controls.Add(last); var lbl5 = new Label(); lbl5.Text = " "; if (place != null) place.Controls.Add(lbl5); } The paging works if I don't use custom paging, but I really need to use the custom paging. I can't figure out why the PageIndexChanging event isn't fired when I'm using the custom paging. Thanks, Jeff

  • Databind gridview with LINQ

    - by Anders Svensson
    I have two database tables, one for Users of a web site, containing the fields "UserID", "Name" and the foreign key "PageID". And the other with the fields "PageID" (here the primary key), and "Url". I want to be able to show the data in a gridview with data from both tables, and I'd like to do it with databinding in the aspx page. I'm not sure how to do this, though, and I can't find any good examples of this particular situation. Here's what I have so far: <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="LinqBinding._Default" %> <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> </asp:Content> <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <h2> Testing LINQ </h2> <asp:GridView ID="GridView1" runat="server" DataSourceID="LinqDataSourceUsers" AutoGenerateColumns="false"> <Columns> <asp:CommandField ShowSelectButton="True" /> <asp:BoundField DataField="UserID" HeaderText="UserID" /> <asp:BoundField DataField="Name" HeaderText="Name" /> <asp:BoundField DataField="PageID" HeaderText="PageID" /> <asp:TemplateField HeaderText="Pages"> <ItemTemplate <asp:DropDownList ID="DropDownList1" DataSourceID="LinqDataSourcePages" SelectedValue='<%#Bind("PageID") %>' DataTextField="Url" DataValueField="PageID" runat="server"> </asp:DropDownList> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> <asp:LinqDataSource ID="LinqDataSourcePages" runat="server" ContextTypeName="LinqBinding.UserDataContext" EntityTypeName="" TableName="Pages"> </asp:LinqDataSource> <asp:LinqDataSource ID="LinqDataSourceUsers" runat="server" ContextTypeName="LinqBinding.UserDataContext" EntityTypeName="" TableName="Users"> </asp:LinqDataSource> </asp:Content> But this only works in so far as it gets the user table into the gridview (that's not a problem), and I get the page data into the dropdown, but here's the problem: I of course get ALL the page data in there, not just the pages for each user on each row. So how do I put some sort of "where" constraint on dropdown for each row to only show the pages for the user in that row? (Also, to be honest I'm not sure I'm getting the foreign key relationship right, because I'm not too used to working with relationships). EDIT: I think I have set up the relationship incorrectly. I keep getting the message that "Pages" doesn't exist as a property on the User object. And I guess it can't since the relationship right now is one way. So I tried to create a many-to-many relationship. Again, my database knowledge is a bit limited, but I added a so called "junction table" with the fields UserID and PageID, same as the other tables' primary keys. I wasn't able to make both of these primary keys in the junction table though (which it looked like some people had in examples I've seen...but since it wasn't possible I guessed they shouldn't be). Anyway, I created a relationship from each table and created new LINQ classes from that. But then what do I do? I set the junction table as the Linq data source, since I guessed I had to do this to access both tables, but that doesn't work. Then it complains there is no Name property on that object. So how do I access the related tables? Here's what I have now with the many-to-many relationship: <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ManyToMany._Default" %> <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> </asp:Content> <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <h2> Many to many LINQ </h2> <asp:GridView ID="GridView1" runat="server" DataSourceID="LinqDataSource1" AutoGenerateColumns="false"> <Columns> <asp:CommandField ShowSelectButton="True" /> <asp:BoundField DataField="UserID" HeaderText="UserID" /> <asp:BoundField DataField="Name" HeaderText="Name" /> <asp:BoundField DataField="PageID" HeaderText="PageID" /> <asp:TemplateField HeaderText="Pages"> <ItemTemplate> <asp:DropDownList ID="DropDownList1" DataSource='<%#Eval("Pages") %>' SelectedValue='<%#Bind("PageID") %>' DataTextField="Url" DataValueField="PageID" runat="server"> </asp:DropDownList> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> <asp:LinqDataSource ID="LinqDataSource1" runat="server" ContextTypeName="ManyToMany.UserPageDataContext" EntityTypeName="" TableName="UserPages"> </asp:LinqDataSource> </asp:Content>

If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error. So the pager does not work correctly. I think it's because of the Image's Id that has to be generated dinamically but i don't know how to do it. Can someone help me?

  • insert DropDownList and TextField in Gridview

    - by userk
    HI,I need to create a GridView which DataSource is an object. Depending on the object I may need some columns with DropDownLists or TextFields (but not all rows) As I don't know the number or columns, they have to be dynamic. I found this solution: TemplateField t = new TemplateField(); t.HeaderTemplate = new GridViewTemplate("header", "title"); t.ItemTemplate = new GridViewTemplate("combobox", "val"); GridView1.Columns.Add(t); GridView1.DataSource = ds; GridView1.DataBind(); Where GridViewTemplate extends ITemplate. This didn't work for me, it fills all rows of a column and I had no way to control witch DropDownList and TextFields need to be created (object info). All the DropDownLists need to have an ID also only known by the object. There are some way I can do this?
