Right now, if you programmatically increase the RadGridView's font size, the columns get bigger to accommodate. So far, so good. But if you then make the font size smaller, the columns stay the same large-font width. 

Further, double-clicking the gridsplitter that separates the columns after the above procedure doesn't resize the column like it would if you'd manually resized the column and then double-clicking the gridsplitter - instead, nothing happens.

Finally, it would be nice to have a programmatic interface to autosize the columns, something like

MyGrid.Columns(0).AutoSize()

Thanks!

I have a custom column based on GridViewBoundColumnBase. In it I override GetCellContent. If I bind the column to a nested property (MyProperty.SubProperty), what I return in GetCellContent is not shown, instead the nested property's "raw" value is shown.

Attached is a project illustrating the issue.

InvalidOperationException, when sorting or filtering GridView and an observable immutable collection is used in a multithread application.

Currently the new item's properties are validated before editing their values, which is not intuitive, especially for Required, MinLength etc. The correct behavior would suggest that validation should be applied only to "confirmed" property values.

GridViewColumn's IsVisible Binding breaks when you create an instance of a usercontrol.

A workaround for the issue is to use RadObservableCollection as a source collection. Before the items are added to it, call the its SuspendNotifications method. Respectively, after that call the ResumeNotifications one. 

Another approach would be to populate the items through the AddRange method of the collection.
