Question

How to open accordion pane with fade transition effect when I click a button? I tried to code it in server side, it is working but there is no fadetransition.

here is my code…

protected void Button1_Click(object sender, EventArgs e)
{
        Accordions.FadeTransitions = true;
        Accordions.SelectedIndex = 1;    
}

You need to switch selected pane on client.

<asp:Button runat="server" Text="Click Me" OnClientClick="switchPane(1); return false;" />

<script type="text/javascript">
     function switchPane(index) {
          $find("<%= Accordions.ClientID %>_AccordionExtender").set_SelectedIndex(index);
     }
</script>

This approach disables server-side client event.
