I need to check that only one of the two can be checked. Its just that my UI does not respond correctly and I can't expect my users to get out of it that way. Bob "Bob" In a datagridview (vs2005, VB.net) I have two columns that are checkboxes. If I then ckeck the second checbox (cell_2), it gives me the error message but does not return the second checkbox I checked to its unchecked state. Any help appreciated, Bob In a datagridview (vs2005, VB.net) I have two columns that are checkboxes. Its not permissible to have the two selected to true, but they can both be false. Cancel = True End If End If End Sub Say I checked just one checkbox Cell_1 to start, the code allows the change to be made. I press the sacep key after the e,cancel and the message and I get the same problem. I need to check that only one of the two can be checked.

To copy the code in this topic as a single listing, see How to: Validate Data in the Windows Forms Data Grid View Control.The setup: VS 2005 C#The Problem: When I close a form, the current cell that is being edited in the datagridview doesn't save properly to the database (all other cells save properly). If anyone has any ideas they would be very helpful. It looked like a valid method, however, when I tried it it's still not saving. Colecovizion, I'm sorry I didn't pay enough attention to your original post.

I noticed that when I click on the checkbox to uncheck it after the e.cancel executed, that click does not change its value, I can both see in the UI that the value did not change before the cellvalidating event is called and in the cellvalidating event itself, when I set a breakpoint after the line that checks and verify the value of CBool(Datagrid1("Cell_2", e. What I realize now is the the e.cancel will prevent the cell from bieng changed or pushed to the unbderlying database but even when user changes cell back to what it should be or presses esc and cell comes bacj the error icon remains in the row selector. I,m going to make a really simple sample with a realy small Access database and post it here soon. I think common behaviour is so that the user can't leave the cell once validation fails and is forced to correct it before he can leave the cell. But there is a problem in your code, you can't use "Data Grid View[,].
