FindControl GridTemplateColumn

[Justin]

I have a RadGrid with a GridTemplateColumn like so:

<telerik:GridTemplateColumn HeaderText="Account" UniqueName="Account">
    <ItemTemplate>
        <div>
            <asp:DropDownList ID="ddlAccountLookup" Visible="false" runat="server">
            </asp:DropDownList>
            <asp:Label ID="grdAccountName" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "AccountName") %>' /><br />
            <asp:Label ID="grdPhone" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Phone") %>' /><br />
            <asp:Label ID="grdEmail" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Email") %>' />
        </div>
    </ItemTemplate>
    <HeaderStyle CssClass="BigNormalBold" HorizontalAlign="Left" VerticalAlign="Bottom" />
    <ItemStyle CssClass="Normal" />
</telerik:GridTemplateColumn>

I need to find the ddlAccountLookup and make it Visible on PostBack, how would I go about doing this?

Thanks!

Hello Justin,

You can try the following code snippet in ItemDataBound event to access the DropDownList.
C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
 if (e.Item is GridDataItem)
 {
   GridDataItem item = (GridDataItem)e.Item;
   DropDownList ddl=(DropDownList)item.FindControl("ddlAccountLookup");
   ddl.Visible = true;
 }
}

Thanks,
Shinu.

Thanks for the reply. I tried that and it never goes into the If statement. When I set a Breakpoint it says the if is false because Item is a GridItemHeader. Any idea?

Thanks!

                ((e.Item as GridDataItem)["CTest"].FindControl("iTextBox") as TextBox).Text = "item";
            }

            {
                ((e.Item as GridHeaderItem)["CTest"].FindControl("hTextBox") as TextBox).Text = "headeritem";
            }
            if (e.Item is GridFilteringItem)
            {
                ((e.Item as GridFilteringItem)["CTest"].FindControl("fTextBox") as TextBox).Text = "filteritem";
            }
            if (e.Item is GridFooterItem)
            {
                ((e.Item as GridFooterItem)["CTest"].FindControl("fooTextBox") as TextBox).Text = "footeritem";
            }
        }
