The SelectionBackground is not applied to selected cells when the GridCell's Background is customized- From forum 193544

[Álvaro Sánchez López]

• After I handle the cell background (Background property) the Selected style (CellSelectionBrush), that was (gray by default), is not visible anymore. So I am not able to difference when I am selecting cells or not.
  It is related with the opacity of the brush in the cell background but I do not want to reduce the opacity for the cell background. Is there any solution for that? Try to determine if the cell that is being painting is selected is not a solution for me because of the performance.

Hi Álvaro Sánchez López,

Hi  Álvaro Sánchez López,

We apologize for the inconvenience caused.

Unfortunately, we were unable to resolve the reported issue within the promised timeline. Our team is actively investigating the problem, which stems from the arrangement of borders within the GridCell's ControlTemplate. Although the Selected Background is correctly applied, it is being overridden by the GridCell's background due to the current template structure.

Based on our analysis, addressing this issue requires modifications to the ControlTemplate of the GridCell. Therefore, we need additional time to thoroughly review and implement the necessary fix and will include the fix in our NuGet release, which is scheduled for October 08, 2024.

Hi   Álvaro Sánchez López,

We would like to let you know that Essential Studio Weekly NuGet packages (v27.1.53) has been published in nuget.org with the fix for the issue “The SelectionBackground is not applied to selected cells when the GridCell's Background is customized”. Please let us know if you have any concerns in this.

Root Cause Details:

The GridCellBorder background is applied above the SelectionCellBorder background, preventing the SelectionBackground from being displayed.

Hi  Álvaro Sánchez López,

We regret to inform you that the recent changes made to address the issue where the SelectionBackground was not applied to selected cells when the GridCell's background was set have been reverted in the Service Pack release (v27.2.2). This decision was made to align with standard behavior and ensure overall stability. Consequently, the previous behavior has been restored, where the SelectionBackground is not applied to customized GridCells.

We have tested this scenario in the MS DataGrid, and it exhibited the same behavior. When the GridCell background is customized, the SelectionBackground is not applied, and only the GridCell's background is retained when a row is selected. For your reference, we have attached a video demonstrating this behavior in the MS DataGrid.

We sincerely apologize for any inconvenience this may have caused and appreciate your understanding.

Regards,

Malini Selvarasu
