Part of the selection is lost when the ItemsSource of RadGridView is assigned to a VirtualQueryableCollectionView (VQCV) and select all action is executed (with Ctrl+A for example), and then the gridview control is scrolled. 

SearchMode property cannot be set in XAML because SearchStateManager is null initially.

Currently, the ControlPanelItem expose only standard CLR properties. Make them DependencyProperties so they can be data bound.

I am using a RadGridView to display appointments. I am adding paging to the control with RadDataPager. I am setting the ItemSource property for the RadGridView to {Binding Path=PagedSource, ElementName=unscheduledWorkOrdersRadDataPager }. I am then overriding the ConvertDraggedData(object data) method and using the DataObjectHelper class in order to obtain data from the object data parameter and then setting the returned IEnumerable<IOccurence> accordingly.

The problem is that whenever I added paging to the RadGridView. The DataObjectHelper is not able to properly retrieve the dragged data from the object data parameter.

When GridView is bound to items (ICustomTypeDescriptor) which contain a property with a dot in the name, the values in the column are not shown

Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Telerik.Windows.Controls.GridView.DataCellsPresenter', AncestorLevel='1''. BindingExpression:Path=Foreground; DataItem=null; target element is 'ContentControl' (Name='PART_ContentPresenter'); target property is 'Foreground' (type 'Brush'). Such errors are shown when loading data and using some of the newer themes (VisualStudio2019, Fluent, Crystal).

When using INotifyDataErrorInfo, items are still validated even when the ValidationType property is None.

 

Please note that when the AutoGeneratedColumns property is set to true, the item's HasErrors property will be evaluated, but only once.

 

 

We can consider introducing functionality that allows users to conditionally style/format the control in a similar manner as the WinForms feature: https://docs.telerik.com/devtools/winforms/controls/gridview/cells/conditional-formatting-cells.

When exporting there are several ways of telling the exporting class which column to exclude during export (through options or by cancelling the export of the column in an event). It would be easier if there was an "IsExportable" property on GridViewDataColumn so that the export can take that into account. No options or events would then be necessary when exporting.

Using SearchPanel and getting search results highlighted is a very usefull feature. However at the moment it is only possible to change the color of the highlight-portion of HighlightTextBlock. It would be nice if I have more formatting options like:

• HighlightFontWeight
• HighlightFontStyle

etc. So if I search for "find" I get results like "find me"

Provide a way to change the ItemsSource of the control while it is exporting using SpreadStreamExport.RunExportAsync() method

When SpreadStreamExport.RunExportAsync() method is exporting large data it could take a while to export the grid. While exporting the grid, the ItemsSource changes to a new one with a different number of columns, NullReferenceException is thrown.

Currently, when you scroll the RadGridView control the "click here to add new row" button goes out of the viewport. Allow to pin the button, so it float at the top or bottom of the viewport and to be always visible.

 Expose mechanism to choose between loading all items or load only the items having containers

The user wants an API with which he can set a formula. For example, the string "=A1+B1" will be translated in Excel like a formula.

The MatchAllTerms search mode doesn't behave as epxected when the GroupRenderMode property of RadGridView is set to Flat.

To work this around, set the GroupRenderMode property of RadGridView to True.

When there isn't a vertical scrollbar visible, while performing a drag selection, empty rows appear.

GridViewSpreadStreamExport throws exception exporting the control whit nested column groups and EnableColumnGroupsVirtualization set to False.

Add mechanism to exclude columns from exporting when using GridViewSpreadStreamExport
