It might be problem due to update panel,

You have put the AjaxFileUpload inside the update panel, so update panel controls not update all controls when ever your label fill with text in AjaxFileUpload1_UploadComplete event.

So please try after remove update panel or set the property UpdateMode="Conditional" of update panel.

Hope this will helpful to solve out your problem.

The latest version of the ajax file upload comes with an update progress.So if you use it, you don't have to put a label to display the failure/success text. For more information and demo see this page : http://stephenwalther.com/archive/2012/05/01/ajax-control-toolkit-may-2012-release.aspx

function ReBindMaterialsGrid() {
    if (rebindTimer == null) {
        SetRebindTimeout();
    } else {
        clearTimeout(rebindTimer);
        SetRebindTimeout();
    }
}
function SetRebindTimeout() {
    rebindTimer = setTimeout(
        'var btn = document.getElementById("MainContent_AdminTabs_TabContainerMain_TabPanelMaterials_Materials_btnReBindGrid");' +
        'btn.click();', 8888);
}
