How to Merge Empty Cells in DataGridView in Wisej

Hello everyone,

I am working on a Wisej project where I have a DataGridView with a column displaying dates. Some cells in this column are empty, and I would like to visually “merge” these empty cells with the cells above that contain data.

The idea is to make the empty cells appear as part of the previous row that has data. Essentially, I want to make these empty cells’ borders invisible or somehow combine them with the previous row’s cell, but I cannot find a way to implement this.

I’ve tried using the CellPaint event, but it doesn’t seem to achieve the desired effect in Wisej. I understand that Wisej doesn’t support the CellPainting event like in WinForms, and I’m looking for guidance on how to implement this behavior in Wisej.

Could anyone please provide a solution or workaround to merge cells visually based on this requirement? Is there any recommended approach to achieve this in Wisej’s DataGridView?

I Use Wisej 3.5 and VB.net

Thank you in advance for your assistance!
