  • Update TargetControls collection with AJAX


    There are situations when the RadToolTipManager's TargetControls collection should be updated. This example shows a common scenario when this should be done - it contains a RadGrid which has its paging and sorting turned on. Every time a page is changed or the grid is sorted, it is updated through AJAX and the RadToolTipManager's TargetControls collection should get updated, too. In order to achieve this, both the grid and the RadToolTipManager are ajaxified by using a RadAjaxManager control.

    Note, that when the page index is changed, or a sorting has been done, the RadToolTipManager's TargetControls collection is cleared because the records on the new grid's page have the same ClientIDs as the old ones.
