I upgraded infragistics version from 11.1 to 11.2
and WEbexplorerbar is causing problem .
Details -
We have a webexplorerbar and attached a clietside click event with explorerbar (no autopostback flag for ItemSelect and ItemClick is attached)
In the Javascript the Itemclick event is handled and after checking some of othersattings we force server side click thru another Asp.button click placed on the form.
<asp:Button ID="btnExplorer" Style="display: none;" runat="server" Text="Explorer Events" OnClick="OnExplorerEvents" />

<script type="text/javascript" language="javascript">

function OnSplitterBarPositionChanged(sender, e) {

var c = document.getElementById(btnExplorerClientId);

c.click();

}

</script>

This code causes the postback but does not fire the click event attached with the button.
