After “Export to Excel” button click other click/postback events disabled on SharePoint custom webpart

Solution I used is added following script on the custom web part

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

//sharepoint postback to work after clicking on export to excel button

if (typeof (_spBodyOnLoadFunctionNames) != 'undefined' &&
                                           _spBodyOnLoadFunctionNames != null)
{
_spBodyOnLoadFunctionNames.push("supressSubmitWraper");

}

function supressSubmitWraper() {

_spSuppressFormOnSubmitWrapper = true;

}

</script>
