UI for WinForms Q1 2007SP2

• RadGridView’s performance has been improved with about 30%. This includes scrolling, resizing, grouping, and applying a theme. 
• Currently we support adding rows through API. Filter doesn't lose focus when typing 
• Implemented a tooltip system for all elements of the grid

    New properties

• GridViewDataColumn.IsGrouped 
• true if grouping on that column is applied
• false otherwise 
• GridViewDataColumn.IsSorted 
• true if sorting on that column is applied
• false otherwise
• Note: When grouping is applied, sorting is obviously applied too. 
• GridViewTemplate.ShowColumnHeaders - show/hide column headers 
• GridViewTemplate.ShowGroupedColumns
• (bool) GridViewTemplate.AutoExpandGroups - when true, after grouping all groups are automatically expanded. Otherwise all groups remain collapsed. The default is false. 
• (bool) GridViewColumn.VisibleInColumnChooser - when true the column is visible in the column chooser, otherwise it is not. The default is true.

• Fixed: Filters did not persist after rebind 
• Fixed: e.CurrentRow.DataBoundItem threw an exception if not set 
• Fixed: ColumnChooser did not keep the proper columns after data source changes 
• Fixed: Columns disappeared when AutoSizeColumnsMode=Fill and the user resized the grid to a width, larger than the available space 
• Fixed: RadGridView did not persist sorting and filtering when data source is updated 
• DataBinding doesn’t fail anymore if the data source does not contain rows 
• Fixed an issued with display objects that contain bitmaps
