Expose a collection which holds the region of the currently selected cells.

The unconfirmed inputs of filter row editors are being destroyed together with the editor itself in column-visualized GridViews. There's an easy solution for it (store what was in there and restore upon recreation) and we're waiting for an official fix for this "expected behaviour" since three+ years.

When the RadGridView is bound to a collection of DynamicObject and runtime we add a new property to the objects, this new property will not be respected. The columns will not be refresh.

Our requirement is to navigate through RadGridView table header using keyboard tab navigation.

The header may or may not include checkbox/filter button.

However on mouse focus on table headers , it get highlighted. This feature is currently not possible with tab navigation.

Same as the one available in Excel. Please check the attached screenshot.

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

The GridViewSelectColumn is a very nice and useful feature, especially the possibility to select all items with just one click on the header. It would be great if there was the same functionality for the group header. So clicking on a checkbox in group header will select all items in this group (only). I know there are some examples (many years old) of how to do this, but it would be much better if it worked out-of-the-box.

You are able to resize columns using the columns gripper. The corresponding group will be automatically resized. We can provide a way to resize the column groups. The columns inside the group will be automatically resized with the group.

Add a separator element under the last pinned row, similar to the frozen columns splitter. The visual could be e horizontal line shown at the bottom border of the row.

The row arrangement is implemented correctly, but because of rounding errors, gaps and rows overlapping may appear during the WPF render phrase. This happens if the boundaries of the row containers use too high precision for its values (top, left, bottom, right). Consider improving this by rounding the boundary values before calling the Arrange() method of the row's container.

For example, we can create the SUM() function for the cells in the ViewPort.

At this moment, the Search As You Type functionality can be customized. We can expose several methods so that the user can override the default search behavior and implement their own.

Provide an option to group a column which is based on an enum by the enum value, but display the DescriptionAttribute or DisplayNameAttribute if existing.
So many times you have sort/group a column by its value like 1,2,3 but display the Description like "Delivery", "Ready", "Pickup". Of course I could add a column to my class which presents the DescriptionAttribute, but then grouping/sorting is wrong: "Delivery", "Pickup", "Ready". It would by much easier if there is an option like "UseDescription". There is something similar with Teleriks "EnumDataSource" which IS using the Description or DisplayName so it should not be that hard to implement the same logic for RadGridView.

It's so strange that Telerik's components don't support such basic mechanics of WPF...

Add support for binding to properties of type GUID.
