[Solved] Event Bubbling from rad grid in user control

[John]

Hi.  I am looking for code sample (VB.NET) to do something in the webpage when the user selects a row in the gridcontrol in a user control.  The user control code is listed below. 

<% @ Control Language="VB" AutoEventWireup="false" CodeFile="YALReadOnlyGrid.ascx.vb" Inherits="UserControls_YALReadOnlyGrid" %>   <% @ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<telerik:RadGrid ID="RadROGrid" runat="server"
     AllowPaging="true" AllowSorting="True" GridLines="None" Skin="Sunset"
    Width="275px">
        <MasterTableView>
            <RowIndicatorColumn>
                <HeaderStyle Width="20px" />
            </RowIndicatorColumn>
            <ExpandCollapseColumn>
                <HeaderStyle Width="20px" />
            </ExpandCollapseColumn>
        </MasterTableView>


        <ClientSettings>
            <Selecting AllowRowSelect="True" />
        </ClientSettings>
</telerik:RadGrid>

In the webpage, the user control is accessed as follows

<%@ Page Title="" Language="VB" MasterPageFile="~/Common/YALMasterPage.master" AutoEventWireup="false" CodeFile="YALDropDowns.aspx.vb" Inherits="Admin_YALDropDowns" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolderHeader" Runat="Server">
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="ConPHLeftTop" Runat="Server">
    <YAL:YALROGenGrid runat="server" ID="YALDDVals" Source="DropDowns" setPageSize="50" />
</asp:Content>
<asp:Content ID="Content4" ContentPlaceHolderID="ConPHLeftBottom" Runat="Server">
</asp:Content>
<asp:Content ID="Content5" ContentPlaceHolderID="ConPHRightTop" Runat="Server">
</asp:Content>

Thanks for any help and/or sample code that you can provide

Hello John,

The following code will help you to access the parent page and control placed in the parent page, when selecting the grid item.

CS:

    protected void RadGridinUC_SelectedIndexChanged(object sender, EventArgs e)
    {
        RadGrid grid = (RadGrid)sender;
        UserControl userControl = (UserControl)grid.NamingContainer; // User control where the grid is placed
        Page pg = (Page)userControl.NamingContainer; // Parent page
        TextBox txtBox = (TextBox)pg.FindControl("TextBox1"); // TextBox is placed in parent page
        txtBox.Text = "hai";
    }

[Also set the ClientSettings -> EnablePostBackOnRowClick propertry to True for grid]

Thanks Shinu!

What does the code on the web page need to be to get to the event.

Hi Shinu!

Do you also have the code sample for a VB.NET app? 

Thanks for your help.

Hi John,

If you want to raise an event from user control to main page, then make use of event delegation technique. Here I found some useful links regarding 'implementing delegates'.
Raise event from user control to main page

And you can easily convert C# code to its VB equivalent by using following code converter.

I will try that out and let you know how that works out.  Thanks for your help
