\nSolution: the most effective solution: add “_spFormOnSubmitCalled=false;_spSuppressFormOnSubmitWrapper=true;” to OnClientClick of the button<\/p>\n
\n<\/div>\n
\n<asp:LinkButton ID=”lbExport”
\nrunat=”server” Text=”Export”
\nOnClick=”lbExport_Click”
\nOnClientClick=”_spFormOnSubmitCalled=false;_spSuppressFormOnSubmitWrapper=true;”\/><\/div>\n

Solution:<\/p>\n

Add this code to the .ascx file<\/p>\n

<script type=”text\/javascript”>
\n    function setFormSubmitToFalse() {
\n        setTimeout(function () { _spFormOnSubmitCalled = false; }, 3000);
\n        return true;
\n    }
\n<\/script><\/p>\n

Then, for the download button, add the code to call this function after user clicks it<\/p>\n

OnClientClick=”setFormSubmitToFalse”<\/p>\n

Another way is to refresh the page on client after certain time<\/p>\n

\n
onclientclick=\"timedRefresh(2000)\"\n\nthen in your html..\n\n    <script type=\"text\/JavaScript\">\n    <!--\n    function timedRefresh(timeoutPeriod) {\n        setTimeout(\"location.reload(true);\",timeoutPeriod);\n    }\n    \/\/   --><\/pre>\n
