Notification regarding navigating through gridview pages

How can I display an alert when a user attempts to page through a gridview? I have implemented a script for this purpose, but the alert appears even if any other buttons on the page are clicked. Ideally, I would like the alert to only show when paging is clicked.

<script type="text/javascript">
    function closeEditorWarning() {
        return 'It seems like you are in the middle of editing something -- if you navigate away, your changes may be lost.'
    }

    window.onbeforeunload = closeEditorWarning
</script>

Any suggestions on how to achieve this specific behavior will be greatly appreciated.

Add a javascript alert to the gridview_pageindexchanging() event like this:

To use Script Manager, follow these steps:

If you have double script tags, include them yourself:

protected void grid_pageindexchanging(object sender, GridViewPageEventArgs e) {
   string script = "<script type=\"text/javascript\">alert('abc');</script>";
   ClientScript.RegisterClientScriptBlock(this.GetType(), "Alert", script);
}

Alternatively, let the method handle it:

protected void grid_pageindexchanging(object sender, GridViewPageEventArgs e) {
   string script = "alert('abc');";
   ClientScript.RegisterClientScriptBlock(this.GetType(), "Alert", script, true);
}

I hope this information is useful.

Update:

Consider adding the following:

using  System.Web.Script.Serialization

Update 2:

Give this a try now:

string script = "alert('its working now!')";
            ScriptManager.RegisterStartupScript(Page, Page.GetType(), "its working",script,true);

For those considering jQuery, one approach is to assign a CSS class to the pager and link your script with the click event for that particular class.

This code snippet, while not verified, could be heading in the correct path:

$('.myClass').click(function () { closeEditorWarning; });
