Question

Hello i added the following button inside of a grid:

<EmptyDataTemplate>
        <asp:Button ID="Button1" runat="server" CssClass="fancy-button" 
            onclick="Button1_Click" Text="Adauga un spatiu" />

    </EmptyDataTemplate>

The code behind for this:

 protected void Button1_Click(object sender, EventArgs e)
    {

        adsDetails.ChangeMode(DetailsViewMode.Insert);
    }

The button doesn’t fire when i click on it and i tried to add :

 <asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />

I receive : “A control with ID ‘Button1’ could not be found for the trigger in UpdatePanel ‘AddressGridViewUpdatePanel’. “

Any idea how i could fix this?
Thank you.

AsyncPostBackTrigger needs the specified control in the same naming container (see remarks in MSDN) as the parent UpdatePanel.

I suggest you to use ScriptManager.RegisterAsyncPostBackControl to register your button as async trigger instead.
