Release LIB 2019.2.826 (08/26/2019)
My requirement is to give certain rows in the GridView a background color that is read from the database (so it's not a fixed list of colors). I use the RowStyle with a binding to the Background property. When the bound property is null, I fall back on the Transparent color.

This transparent background in combination with a GridViewComboBoxColumn sometimes causes rows to "stick" to the top or bottom of the grid. To simulate this, a ComboBox in the grid must be opened, then you need to scroll up or down until the field is outside the viewport. In some cases, the row sticks to the top or the bottom. After inspecting the Visual Tree, it appears that the row is still part of the Visual Tree, even though it is outside the viewport. I have attached a video and a sample project where you can see and test this behavior.

When invalid rows that were loaded but not in viewport get valid, the invalid state (row validation indicator) is still visible.

I have been working wit the RadGridView for about 6 years now and it works great!

The only thing that still bugs me after all these years is the GridViewComboBoxColumn. The sorting and "Search as you type" features are not working for us. The fact that it uses the DataMemberBinding is something we do not get.

The fact that it is not ordered or searched into the shown value instead of the DataMemberPath is beyond me.

I mean, why would I, as a user, want to search into or sort a value that is not visible to me?


Adding a feature like a string property on the GridViewComboBoxColumn that is used for displaying, searching, filtering and sorting would be awesome!

The filter's distinct values work well, but the field filters show the enum value and that's not good.


I have attached a sample project to demonstrate the problems with sorting, filtering and searching.

There are also print screens attached to clarify each feature mentioned

Release LIB 2019.2.805 (08/05/2019)
The GridViewMultiColumnComboBoxColumn of RadGridView allows you to enter the edit mode of the corresponding cells even when the IsReadOnly or IsReadOnlyBinding properties of the column are set to True. 

This is also reproducible when RadGridView.IsReadOnly property is set to True

This is reproducible only when the SelectionMode is set to Multiple.

Currently, a CollectionChanged notification of the bound collection needs to be raised for the Filtering/Sorting/Grouping to be updated.

Loading items in RadGridView takes too much time due to operations executed on the UI.

If the DataMemberBinding of a GridViewMultiColumnComboBoxColumn points to a nested property, the value of that property is displayed in view mode and the DisplayMemberPath is not respected.

As of R1 2018 RadGridView supports pinning columns both on its left and right side. The new properties that control the right-side behavior are: RightFrozenColumnCount and RightFrozenColumnsSplitterVisibility.

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.

When loading the columns from a file the columns are read in the order they are found in the Columns collection of RadGridView upon saving them.
Setting the DisplayIndex triggers the internal grid logic that ensures the DisplayIndex of each column is correct. 
The combination of the above two operations can cause the grid to invalidate the DisplayIndex of columns while deserializing them and thus setting invalid values.
To ensure correct behaviour when deserializing sort the columns by their display order property before returning them in ProvideValue()

Release R2 2019 SP1
This is reproduced when the RadGridView is bound to a ListCollectionView and it is grouped. In such a case, when an item is edited, it is brought to the bottom of the group.

Release R2 2019 SP1
When navigating through the cells with the left/right arrow keys, when the last column is reached normally the focus stays on that cell. However, when there are invisible columns on the left/right of the last visible one, the focus moves away from the grid.

As a workaround you can handle the PreviewKeyDown event of the RadGridView when the CurrentColumn is the last visible one.

When the ItemsSource of the RadGridView is reset, disctinct values remain checked in the Filtering Popup. 

For a workaround, check the attached project.
