I set a cell to a checkbox and whenever I check/uncheck a second time I get an object reference error. If I select a different cell/row then it works the second time.
Hi Mark,
I cannot reproduce here in a simple test case.
Are you setting the column type to DataGridViewCheckBoxColumn in the designer or dynamically ?
Is the cell data bound ? Any event handlers attached ?
Maybe you can share some more information or a simplified test case ?
Thanks in advance.
Best regards
Frank
