Solution: the most effective solution: add “_spFormOnSubmitCalled=false;_spSuppressFormOnSubmitWrapper=true;” to OnClientClick of the button
<asp:LinkButton ID=”lbExport”
runat=”server” Text=”Export”
OnClick=”lbExport_Click”
OnClientClick=”_spFormOnSubmitCalled=false;_spSuppressFormOnSubmitWrapper=true;”/>
runat=”server” Text=”Export”
OnClick=”lbExport_Click”
OnClientClick=”_spFormOnSubmitCalled=false;_spSuppressFormOnSubmitWrapper=true;”/>
Solution:
Add this code to the .ascx file
<script type=”text/javascript”>
function setFormSubmitToFalse() {
setTimeout(function () { _spFormOnSubmitCalled = false; }, 3000);
return true;
}
</script>
Then, for the download button, add the code to call this function after user clicks it
OnClientClick=”setFormSubmitToFalse”
Another way is to refresh the page on client after certain time
onclientclick="timedRefresh(2000)"
then in your html..
<script type="text/JavaScript">
<!--
function timedRefresh(timeoutPeriod) {
setTimeout("location.reload(true);",timeoutPeriod);
}
// -->
