  • WPF textbox derived control override drag&drop OnPreviewDrop (C sharp)

    - by Petr Klus
    Hi, I have been working on my custom control derived from the TextBox and I have encountered a problem I can not solve right now. Brief description of the problem: my textbox contains plain text which contains tags which I want to keep consistent - so far I have overriden text selection so they can be selected only as a whole tag etc. Right now I have moved to processing of drag&drop. If any text is dropped on the textfield and it is dropped on the tag, I want the insertion to be moved before or after the tag. The actual problem is with setting of the e.Handled=true. If I set it to true, it almost works - the text is inserted via my routine, but it is not removed from the source. If I set it to false, after executing my method the original textbox's insertion method is run. Is there any way to alter event routing? Or am I approaching this wrong from the start? Code of my method: protected override void OnPreviewDragEnter(DragEventArgs e) { base.OnPreviewDragEnter(e); e.Handled = true; // let us draw our very own caret... } protected override void OnPreviewDrop(DragEventArgs e) { base.OnPreviewDrop(e); fieldsReady = false; int selStart = this.SelectionStart; int selLength = this.SelectionLength; string droppedData = (string)e.Data.GetData(DataFormats.StringFormat); // where to insert Point whereDropped = e.GetPosition(this); int droppedIndex = GetCharacterIndexFromPoint(whereDropped, true); if (droppedIndex == this.Text.Length - 1) { double c = GetRectFromCharacterIndex(droppedIndex).X; if (whereDropped.X > c) droppedIndex++; } // only if the source was us, do this: if (this.SelectionLength > 0) // this means that we are dragging from our textbox! { // was there any selection? if so, remove it! this.Text = this.Text.Substring(0, selStart) + this.Text.Substring(selStart + selLength); e.Handled = true; // 2DO!! alter the indices depending on the removed selection // insertion this.Text = this.Text.Substring(0, droppedIndex) + droppedData + this.Text.Substring(droppedIndex); } }

  • User control events not getting to their handlers

    - by PhrkOnLsh
    I am trying to create a user control to wrap around the Membership API (A set of custom Gridviews to display the data better) and, while the code and the controls worked fine in the page, when I moved them to an .ascx, the events stopped firing to it. <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CustomMembership.ascx.cs" Inherits="CCGlink.CustomMembership" %> <asp:Panel ID="mainPnl" runat="server"> <asp:Label id="lblError" ForeColor="Red" Font-Bold="true" runat="server" /> <asp:GridView id="grdUsers" HeaderStyle-cssclass="<%# _headercss %>" RowStyle-cssclass="<%# _rowcss %>" AlternatingRowStyle-cssclass="<%# _alternatingcss %>" OnRowUpdating="grdUsers_RowUpdating" OnRowDeleting="grdUsers_RowDeleting" OnRowCancelingEdit="grdUsers_cancelEdit" autogeneratecolumns="false" allowsorting="true" AllowPaging="true" EmptyDataText="No users..." pagesize="<%# PageSizeForBoth %>" runat="server"> <!-- ...columns... --> </asp:GridView> <asp:Button id="btnAllDetails" onclick="btnAllDetails_clicked" text="Full Info" runat="server" /> <asp:GridView DataKeyNames="UserName" HeaderStyle-cssclass="<%# _headercss %>" RowStyle-cssclass="<%# _rowcss %>" AlternatingRowStyle-cssclass="<%# _alternatingcss %>" id="grdAllDetails" visible="false" allowsorting="true" EmptyDataText="No users in DB." pagesize="<%# PageSizeForBoth %>" runat="server" /> <asp:Button id="btnDoneAllDetails" onclick="btnAllDetails_clicked" text="Done." Visible="false" runat="server" /> </asp:Panel> However, none of the events in the first two controls (the gridview grdUsers and the button btnAllDetails) simply do NOT occur, I have verified this in the debugger. If they occured just fine in the aspx page, why do they die on moving to the ascx? My code in the aspx now is: <div class="admin-right"> <asp:ScriptManager ID="sm1" runat="server" /> <h1>User Management</h1> <div class="admin-right-users"> <asp:UpdatePanel ID="up1" runat="server"> <ContentTemplate> <cm1:CustomMembership id="showUsers" PageSizeForBoth="9" AlternatingRowStylecssclass="alternating" RowStylecssclass="row" DataSource="srcUsers" HeaderStylecssclass="header" runat="server" /> </ContentTemplate> </asp:UpdatePanel> </div> Thanks.

    - by Dave Colwell
    Hi all, simple question regarding property value inheritance in UserControls. If i create a UserControl, it has some standard properties like Background, BorderBrush and BorderThickness. Within that UserControl i have a border. I want to know, if i dont specify any set value or binding for the property BorderBrush of that border, will it automatically inherit the value of BorderBrush from the parent control? Thanks!

  • Silverlight MVVM add record from user control

    - by strattonn
    I have a User Control for searching container numbers. If the user enters a container number that's new to the system then I want to tell the VM "I have a new record to add". The MVVM method avoids using Events to communicate with the VM as they create code-behind. Should I create a Dependency Property to trigger the VM but I don't think I've seen other controls with a "NewRecord" property? Any thoughts?
