Hi,

Unfortunately there is no such built-in feature in UltraWebTab. However, tab exposes various ClientSideEvents and allows to customize appearance of tab-label. Example below shows how to add image after text and how to close tab when that image is clicked by user.

<script type="text/javascript">
function UltraWebTab1_Click(oWebTab, oTab, oEvent)
{
 var src = oEvent.event.srcElement;
 if(!src)
    src = oEvent.event.target;
 //if(!src){alert("no src");return;}
 if(src.nodeName != 'IMG' || src.src.indexOf("close.gif") < 0)
    return;
 // Note: a simple call like oTab.setVisible(false) can not be used, because
 // a browser may lock element related to event and request to change visibility will fail.
 // So, request to hide tab should be moved in another "thread":
 var command = "igtab_getTabById('" + oWebTab.ID + "').Tabs[" + oTab.index + "].setVisible(false)";
 window.setTimeout(command, 0);
}
</script>

<igtab:UltraWebTab ID="UltraWebTab1" runat="server" Height="150px" Width="267px">
 <ClientSideEvents Click="UltraWebTab1_Click" />
 <Tabs>
   <igtab:Tab Text="New Tab<img src='./images/close.gif' />"></igtab:Tab>
   <igtab:Tab Text="New Tab<img src='./images/close.gif' />"></igtab:Tab>
   <igtab:Tab Text="New Tab<img src='./images/close.gif' />"></igtab:Tab>
  </Tabs>
</igtab:UltraWebTab>
