Hi,

Try accessing the Detailtemplate as shown below.
aspx:
<telerik:RadTreeList runat="server" ID="RadTreeList1" DataSourceID="SqlDataSource1" AutoGenerateColumns="false" onitemcommand="RadTreeList1_ItemCommand">
   <DetailTemplate>
      <asp:Button ID="Button1" CommandName="Select" runat="server" Text="select" />
      <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
   </DetailTemplate>
    <Columns>
     . . .
    </Columns>
</telerik:RadTreeList>
C#:
protected void RadTreeList1_ItemCommand(object sender, Telerik.Web.UI.TreeListCommandEventArgs e)
{
   if (e.CommandName == "Select")
   {
     TreeListDetailTemplateItem item = (TreeListDetailTemplateItem)e.Item;
     TextBox txt = (TextBox)item.FindControl("TextBox1");
   }
}

Thanks,
Shinu.

Hi Shinu,

I already tried what you suggested. Giving me the below mentioned error for casting, since my
<asp:Button ID="Button1" CommandName="Select" runat="server" Text="select" />
is in TreeListTemplateColumn.

Thanks

Hi Gopi,

If your RadButton is placed in a TreeListItem, you should use the FindControl method from that item, because it could not be found from the ContentPlaceHolder.

If you need any further assistance with this, please elaborate on your exact scenario, so we can give an example, relevant to it.

ContentPlaceHolder contentPage = this.Page.Master.FindControl("ContentPlaceHolder1") as ContentPlaceHolder;
RadButton R = sender as RadButton;
RadButton radbutton1 = R.Parent.FindControl("RadButton1") as RadButton;


}

Hello Gopi,

As I have explained in my previous posts, in order to get reference to a control placed within a a RadTreeList item, you should call the FindControl method from that item.

Once again, if you continue to have problems with this, please provide more details on your exact scenario and the requirement that you have.
