You can toggle filterstatus value like this

filterstatus ^= 1;

So your function looks like

function showFilterItem(objButton) {
if (filterstatus == 0) {
    $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().showFilterItem();
    objButton.value = "Hide Filter";
}
else {
    $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().hideFilterItem();
    objButton.value = "Show filter";
}
  filterstatus ^= 1;    
}
