Fire button event in RadGrid

[Simon]

Hey!

I have a GridTemplateColumn where I define a TextBox and a Button in the EditItemTemplate property. How is it possible to fire the onClick event of the button.

I have tried the following:

<asp:ImageButton ID="Button" runat="server" ImageUrl="~/Resources/key.png" OnClick="Button_Click" />

... but this doesn't work I always get the following compilation error "...does not contain a definition for 'Button_Click' and no extension method ... (are you missing a using directive or an assembly reference?)".

I don't know what I made wrong - can anybody help me?

Hello Simon,

Have you added the Button_Click event on server code?

C#:

protected void Button_Click(object sender, EventArgs e)

{

// Your code

}

Another option is setting the CommandName for button and check for the CommandName in ItemCommand event.

ASPX:

<telerik:GridTemplateColumn>
    <EditItemTemplate>
        <asp:ImageButton ID="ImageButton1" runat="server" CommandName="custom" />
    </EditItemTemplate>
</telerik:GridTemplateColumn>

C#:

    protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "custom")
        {
            // Your code
        }
    }

-Shinu.

Hello Shinu!

Thank you very much for your help.

Now I have found what I made wrong. I have added the Butten_Click event on server code but I choosed the wrong access modifier for the methode - I haven't seen that, this was my mistake. Therefore I always get the error on compilation time.

Now everything works. Thank you!

Hi Kokila,

I prepared a small sample where I get the selected items on the server. Please check out the attached sample and let me know how it differs form your real setup?
