Hi,

If you ask how to run script on button click, then WebImageButton supports 2 options.

1. Set explicit script statements
2. Set name of function which will be called on click

You also probably will want to disable default autopostback.

Below examples for 2 cases:

<script type="text/javascript">
function WebImageButton2_Click(oButton, oEvent)
{
  alert('WebImageButton2_Click');
}
</script>

<igtxt:WebImageButton ID="WebImageButton2" runat="server" AutoSubmit="False">
  <ClientSideEvents Click="WebImageButton2_Click" />
</igtxt:WebImageButton>

<igtxt:WebImageButton ID="WebImageButton1" runat="server">
  <ClientSideEvents Click="alert('click')" />
</igtxt:WebImageButton>
