    Q1 release of RadControls for ASP.NET AJAX will require .NET 3.5 Service Pack 1

    February 12, 2010 Share
    Starting with the Q1 2010 release we’ll be building against .NET 3.5 SP1. This is a new requirement and older releases are still compatible with .NET 3.5 RTM. There is no change in the requirements for the .NET 2.0 builds. Generally speaking, there is no reason why you shouldn’t install .NET 3.5 SP1 on your servers and workstations since this is the current official version of the framework. The reason for this requirement is that we’ll start shipping official .NET 4.0 builds of RadControls for ASP.NET AJAX when VS 2010/.NET 4 RTM comes out. The service pack is a prerequisite for using the 4.0...

The content inside your HTML container marked by this CSS...

    Hi everyone, As of Q1 2010 RadGrid will be equipped with a new filtering menu – a powerful and flexible feature the interest in which was sparked by RadGrid’s MVC counterpart offered by Telerik. 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...
