FindControl in Grid/MasterTableview/DetailTables/...

[Tim]

Having a bit of trouble just finding a control in this.
I have cleared out most code for an easier read and left the main tags in place.
Need to find the SqlDataSource and I have tried everything with no luck....

 

 

    <telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="odsFill" GridLines="None"
    AllowPaging="True" Width="950px" DataKeyNames="xxx">
    <MasterTableView DataSourceID="odsFill" AutoGenerateColumns="False" DataKeyNames="xxx"
        AllowPaging="true">
        <RowIndicatorColumn HeaderStyle-Width="20px" />
        <ExpandCollapseColumn HeaderStyle-Width="20px" />
        <Columns>

        </Columns>

Hello Tim,

The following code snippet shows how to access the control  from an an external button click event.

C#:

protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
                GridTableView tableView = (GridTableView)item.ChildItem.NestedTableViews[0];
                foreach (GridNestedViewItem childitem in tableView.GetItems(GridItemType.NestedView))
                {
                     RadPageView pageView = (RadPageView)childitem.FindControl("PageView3");
                    SqlDataSource source = (SqlDataSource)pageView.FindControl("SqlDataSource1");
                }
        }
    }

Thanks,
Princy.

Thanks for the info. I am able to access it now but ran into another problem.
I am trying to set the connection string for the sqldatasource.
I am encrypting it in the web.config. (I inherited this app)

Now, if I set it in the page Init, no data comes back like it should.
If I set it in the page load and on each post back, the error comes up that the conn string has not been initialized.

Suggestions on this?

Thanks in advance...

Hi Tim,

Try to decrypt the connection string on Page_PreInit event.

Best wishes,
