    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  
            }      
        }

    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?
