  • Calculate total by javascript in gridview with paging

    - by louis
    Without paging function, i can loop through the gridview by using var sum = 0; var gridViewCtlId = '<%=timesheetView.ClientID%>'; var grid = document.getElementById(gridViewCtlId); var gridLength = grid.rows.length; so with gridLength i can loop through the gridview to sum all rows. However, when I use paging event of gridview, i use the page size to loop through all rows, but it occurs errors because the last page may not have enough rows. So would you please to help me how to get the rows in the each page of gridview?

  • Gridview with row headers

    - by Seagull
    I am using the ASP.NET3.5 gridview control in a new project. My problem is that the gridview presents data in basic tabular format, whereas I want a grid with row header / grouping behaviors. An example of this would be Outlook web interface, which can group emails by date, as well as allowing you to select individual emails to display. My problem: I can't see how this could be easily done with Gridview? I did find a product called Telerik that has a seemingly fancy Gridview, but I am hesitant to spend money on a single components that now also locks me into a third-party framework...

  • Find package name for Android apps to use Intent to launch Market app

    - by eom
    I'm creating a mobile website that will include a page from which people can download relevant apps that we recommend. I've found good instructions for creating the links to launch the Market but this assumes that you are the developer of the app in question and know the exact package name. Is there any way to get the package name, other than just contacting the developers and asking? For the iPhone, I found easy instructions for getting the URL I need from the iTunes store, so I'm looking for info like that.

  • Binding DataTable To GridView, But No Rows In GridViewRowCollection Despite GridView Population?

    - by KSwift87
    Problem: I've coded a GridView in the markup in a page. I have coded a DataTable in the code-behind that takes data from a collection of custom objects. I then bind that DataTable to the GridView. (Specific problem mentioned a couple code-snippets below.) GridView Markup: <asp:GridView ID="gvCart" runat="server" CssClass="pList" AutoGenerateColumns="false" DataKeyNames="ProductID"> <Columns> <asp:BoundField DataField="ProductID" HeaderText="ProductID" /> <asp:BoundField DataField="Name" HeaderText="ProductName" /> <asp:ImageField DataImageUrlField="Thumbnail" HeaderText="Thumbnail"></asp:ImageField> <asp:BoundField DataField="Unit Price" HeaderText="Unit Price" /> <asp:TemplateField HeaderText="Quantity"> <ItemTemplate> <asp:TextBox ID="Quantity" runat="server" Text="<%# Bind('Quantity') %>" Width="25px"></asp:TextBox> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="Total Price" HeaderText="Total Price" /> </Columns> </asp:GridView> DataTable Code-Behind: private void View(List<OrderItem> cart) { DataSet ds = new DataSet(); DataTable dt = ds.Tables.Add("Cart"); if (cart != null) { dt.Columns.Add("ProductID"); dt.Columns.Add("Name"); dt.Columns.Add("Thumbnail"); dt.Columns.Add("Unit Price"); dt.Columns.Add("Quantity"); dt.Columns.Add("Total Price"); foreach (OrderItem item in cart) { DataRow dr = dt.NewRow(); dr["ProductID"] = item.productId.ToString(); dr["Name"] = item.productName; dr["Thumbnail"] = ResolveUrl(item.productThumbnail); dr["Unit Price"] = "$" + item.productPrice.ToString(); dr["Quantity"] = item.productQuantity.ToString(); dr["Total Price"] = "$" + (item.productPrice * item.productQuantity).ToString(); dt.Rows.Add(dr); } gvCart.DataSource = dt; gvCart.DataBind(); gvCart.Width = 500; for (int counter = 0; counter < gvCart.Rows.Count; counter++) { gvCart.Rows[counter].Cells.Add(Common.createCell("<a href='cart.aspx?action=update&prodId=" + gvCart.Rows[counter].Cells[0].Text + "'>Update</a><br /><a href='cart.aspx?action='action=remove&prodId=" + gvCart.Rows[counter].Cells[0].Text + "/>Remove</a>")); } } } Error occurs below in the foreach - the GridViewRowCollection is empty! private void Update(string prodId) { List<OrderItem> cart = (List<OrderItem>)Session["cart"]; int uQty = 0; foreach (GridViewRow gvr in gvCart.Rows) { if (gvr.RowType == DataControlRowType.DataRow) { if (gvr.Cells[0].Text == prodId) { uQty = int.Parse(((TextBox)gvr.Cells[4].FindControl("Quantity")).Text); } } } Goal: I'm basically trying to find a way to update the data in my GridView (and more importantly my cart Session object) without having to do everything else I've seen online such as utilizing OnRowUpdate, etc. Could someone please tell me why gvCart.Rows is empty and/or how I could accomplish my goal without utilizing OnRowUpdate, etc.? When I execute this code, the GridView gets populated but for some reason I can't access any of its rows in the code-behind.

  • ASP.NET GridView Sort?

    - by Curtis White
    I'm performing a query with a sort in the Selecting event of the LinqDataSource. I'm then casting my query to a list and assigning it to the result. I'm using this data source in an ASP.NET gridview. I can see the list is sorted but when the ASP.NET gridview does not seem to be respecting the sort order. How can I get the gridview to respect my default sort order?

  • Ghost activity in android

    - by Ari
    My application works as follow: On start I have some AppStartActivity which does something, finishes itself and starts MainActivity if user is logged in or LoginActivity otherwise. LoginActivity finishes itself and starts MainActivity when user log in successfully. On MainActivity I have SomeActivity from which user can logout. Activity stack for this situation is MainActivity > SomeActivity. It is correct, back button works well. When user click LogOut button there is a problem. I need to show LoginActivity but I don't want to have MainActivity and SomeActivity on activity stack anymore. I could resolve this problem if I wouldn't finish AppStartActivity. I could go back then with flag FLAG_ACTIVITY_CLEAR_TOP and it would work well. But here is a problem with back button. I don't want user to come back to this activity with back button. I want it to exit app instead. UPDATED: Flags FLAG_ACTIVITY_NEW_TASK and FLAG_ACTIVITY_CLEAR_TASK would be best, but I need it working in API level 9.

    Hi, I would like to get some links for getting started with design patterns.My requirement is , (at Initial stage) How to go about developing a particular pattern , say customized ListView which can be shared across applications . e.g. Applications will call something like drawCustomizedListView(params...) and my code will draw the listview according to the parameters supplied. This is particularly useful when across the applications I have to draw customized views. My intention is, I should not repeat the same code everywhere for doing similar task. Any references for the above requirement ?

  • Android - Correspondence between ImageView coordinates and Bitmap Pixels

    - by Matteo
    In my application I want the user to be able to select some content of an Image contained inside an ImageView. To select the content I subclassed the ImageView class making it implement the OnTouchListener so to draw over it a rectangle with borders decided by the user. Here is an example of the result of the drawing (to have an idea you can think of it as when you click with the mouse on your desktop and drag the mouse): Now I need to determine which pixels of the Bitmap image correspond to the selected part. It's kind of easy to determine which are the points of the ImageView belonging to the rectangle, but I don't know how to get the correspondent pixels, since the ImageView has a different aspect ratio than the original image. I followed the approach described especially here, but also here, but am not fully satisfied because in my opinion the correspondence made is 1 on 1 between pixels and points on the ImageView and does not give me all the correspondent pixels on the original image to the selected area. Calling hoveredRect the rectangle on the ImageView the points inside of it are: class Point { float x, y; @Override public String toString() { return x + ", " + y; } } Vector<Point> pointsInRect = new Vector<Point>(); for( int x = hoveredRect.left; x <= hoveredRect.right; x++ ){ for( int y = hoveredRect.top; y <= hoveredRect.bottom; y++ ){ Point pointInRect = new Point(); pointInRect.x = x; pointInRect.y = y; pointsInRect.add(pointInRect); } } How can I obtain a Vector<Pixels> pixelsInImage containing the correspondent pixels?

  • Overwrite values when using gridview Edit?

    - by sah302
    I am using a GridView which is bound to a LinqDataSource and using the automatic edit and delete buttons. However, I don't want the user to edit two of the columns manually, but done automatically. Specifically username who last updated the entry, and the date it was updated. The gridview only contains 3 columns: Name, Date modified, last updated by. Right now when the user clicks the edit button they can only edit the name column (other two set to read-only). Upon clicking the update button, I want the other 2 fields to update as well based on some extra code. I thought this was done in the code behind within the event rowUpdating, but it doesn't seem to work. My gridview: <asp:GridView ID="gvNewsSources" runat="server" AutoGenerateColumns="False" DataSourceID="ldsNewsSource" AutoGenerateDeleteButton="True" AutoGenerateEditButton="True" CellPadding="4" ForeColor="#333333" GridLines="None" DataKeyNames="Id"> <RowStyle BackColor="#F7F6F3" ForeColor="#333333" /> <Columns> <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" /> <asp:BoundField DataField="LastUpdatedBy" HeaderText="Last Updated By" SortExpression="LastUpdatedBy" ReadOnly="True" /> <asp:BoundField DataField="DatedModified" HeaderText="Dated Modified" SortExpression="DatedModified" ReadOnly="True" /> </Columns> <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" /> <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" /> <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> <EditRowStyle BackColor="#999999" /> <AlternatingRowStyle BackColor="White" ForeColor="#284775" /> </asp:GridView> My code behind: Partial Class _Default Inherits System.Web.UI.Page Protected Sub gvNewsSources_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles gvNewsSources.RowUpdating e.NewValues("LastUpdatedBy") = GetUser.GetUserName e.NewValues("DateModified") = Date.Now() lblOutput.Text = e.NewValues("DateModified").ToString() End Sub End Class Yet when I run through this, I get no errors, but the values aren't being updated in the database or in the gridview. I ran through debug mode and the new values dictionary starts at 1 and ends up being 3 by the end of the rowUpdating event and the value is being set (tested by output the newValue of Datemodified), but it isn't saving. What am I doing wrong?

  • Android EditText within a ListView

    - by metalideath
    I have created a custom Array Adapter to bind a custom row that contains some static text and an editable EditText. I am trying to register to be notified when the user changes the text within the edit text and when notified to determine which ArrayList row the modified EditText corresponds to. In the past with other types of views such as a Spinner I could simply put a reference to the parent view and the row number into the tag for the Spinner view. And then when I was notified that the value changed I read the tag to determine how to correlate it back to the master ArrayList. The problem with registering to be notifed with an EditText change is that you do not get back a view but instead get a TextWatcher and I have no way to correlate back to the parent view or ArrayList row. What is the technique that you need to use in this circumstance?
