Providing subclasses of DatagridViewRowHeaderCell and DataGridViewTopLeftHeaderCell

[dtoffe]

Hi,

I want to use a DataGridView providing my own implementation of DataGridViewRowHeaderCell and DataGridViewTopLeftHeaderCell, so that I can put CheckBoxes in them.

I add the new classes in the form loading, and the checkboxes work fine, but if i sort the DataGridView, the DataGridView seems to be repainted and my cells are replaced by standard header cells.

So I add my implementations again in the OnPrePaint event of the DataGridView and now my implementation are shows even when I sort the DataGridView, but it flickers as if it were continually repainting everything.

What is the proper way of providing my own implementations of DatagridViewRowHeaderCell and DataGridViewTopLeftHeaderCell ??

Thanks,

Daniel
