Sharepoint SPGridView control is expanded by default

The Sharepoint SPGridView control seems to be rendered as expanded sometimes, although it should be collapsed.

Here is a javascript function to fix this issue:

function spGridViewFixExpandedGroups(gridviewId) {
    var gridview = $("[id$='" + gridviewId + "']");
    var links = gridview.find("tr[isexp='true'] a[title='Expand/Collapse']");
    links.click();
}

Simply call the script upon page load. Note: The script requires the jQuery library to be included.
