    Built-in filtering support for RadListView ASP.NET AJAX

    Beside of all the other new neat features the RadListView for ASP.NET AJAX will have with the Q1 2010 release, it will also incorporate built-in filtering capabilities.

It will be a sub-part of RadGrid's header context menu and will allow for filtering the grid's data on two conditions related with a logical AND operator: Perhaps, many of you are already eager to know how the new feature should be switched on/off. For this purpose a new property has been introduced into the RadGrid control -RadGrid.EnableHeaderContextFilterMenu/GridTableView.EnableHeaderContextFilterMenu. In addition, it is important that RadGrid.EnableHeaderContextMenu/ GridTableView.EnableHeaderContextMenu and RadGrid.AllowFilteringByColumn/GridTableView.AllowFilteringByColumn properties be...
