In Office2016 when we increase the DPI of the Windows a left border in the header of column disappears. As a workaround you can set the Width property of all columns.

 Group rows which are not present in the view are not visualized when the window is maximized.

A possible solution here is to set the GroupRenderMode property to Flat.

When there are items with longer text than the FilteringControl's default width, the FilteringControl resizes when scrolling to these items. This behavior is observed with all themes, different from Windows 8 and Windows 8 Touch.

This happens only if there are many columns outside of the viewport (a scrollviewer is shown), with their TabStopMode property set to Skip.

In this case, the navigation needs some time in order to get to the next row and select the first available cell.

A possible workaround for this would be to implement a custom Keyboard Command Provider, and to replace the MoveNext command with a custom one, that moves the current cell, by setting the CurrentCellInfo property of RadGridView.

Add property to control whether the filtering dropdowns stay open.

When adding a new row (before committing it) and we switch between the cells the RowValidating event is called every time.

If you have the following model, the columns that show the Test and Date properties (in the derived class) cannot be sorted or filtered. Also, no header text is displayed.

 

To work this around, set the IsCustomSorting property of the corresponding columns and implement a custom sorting in the Sorting event of RadGridView.

 

Bind a grid to a DataView

Start editing and change the values of a few cells.

Press Escape twice to cancel the edit of the entire row.

Expected: the values return to the old values

Actual: the values remain the last entered ones

The fix for this issue is available with LIB (version 2018.3.1126) published on Monday, November 26.

 

Currently the string is localized as "Filtre" and it should be localized as "Filtrer".

When we make frozen column width bigger than the window will hide other columns. Scrolling is applied only to not frozen columns. So we can't scroll to see other columns.

A possible workaround is to set MaxWidth property of the column.

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.

Sample:
<telerik:RadGridView ShowSearchPanel="true" ShowSearchPanelCloseButton="false"
or
<telerik:RadGridView ShowSearchPanel="true" ShowSearchPanelCloseButton="Hidden"

When the new value is selected from the GridViewMultiColumnComboBoxColumn, the event arguments in the CellEditEnded event does not contain the new value. 

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.

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.
