Find control inside InsertItemTemplate

[Rem]

Hi,

I have to find the control inside InsertItemTemplate during itemdatabound.

[Shinu]

Hi Rem,

Please have a look into the following code snippet to access a TextBox in InsertItemTemplate:

ASPX:

<telerik:GridTemplateColumn HeaderText="Column1">
    <InsertItemTemplate>
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    </InsertItemTemplate>
</telerik:GridTemplateColumn>

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditFormInsertItem && e.Item.OwnerTableView.IsItemInserted)
    {
      GridEditFormInsertItem edit = (GridEditFormInsertItem)e.Item;
      TextBox txt = (TextBox)edit.FindControl("TextBox1"); // Access the Textbox Control
    }
}

Thanks,
Shinu

Hi,

I tried it, but unable to satisfy the condition GridEditFormInsertItem. My code is;

</Columns>
                    </MasterTableView>
                </telerik:RadGrid>

I want to assign clientevent to the combobox from codebehind.

Hi Rem,

I have notice that you are using Batch edit mode, which is handling the editing entirely on client-side and the approach that Shinu provided could not be used with Batch editing. Please note that key element of the batch editing mode is that it uses only one editor for a single column. Detail information could be found at the following help article:

• Batch Editing

In the help article you will also find information on how to get reference to BatchColumnEditor for each column.

Hope that helps.
