Use cellvalidating event datagridview

Hi there, I have a question regarding datagridview, I add data to the datagridview in an interface and all the validation for the datagridview cell is in the datagridview cell validating event for the datagridview.I display the data of the is datagridview in another interface and make the cells read-only. But the thing is when I click on a row that data was added previously and press the Add new row the cell validating event is triggered.In a lot of books and articles that I've read on this control, it seems to suggest that the appropriate event to handle for this is the Cell Validating one. However, this event triggers a bit too often for my tastes and I'm not sure it is required.For example, this event triggers everytimes the users switches to another row.How can I disable the cell validating event for the rows that was added before???

I can't consistently reproduce this error; when I enter the debugger typically if I try and break at the cell validating step I find that it's not being called during the clear, as I expect. To String())) break; //more cases for each column The problem turned out to be that I was sometimes clearing the data Grid View with a cell in the identifier column selected and thus in focus. The first column is an identifier, which must be a unique 1 or 2 digit number.I use cell validating to ensure that the identifier satisfies these criteria.However sometimes it does break there during the clear and that of course causes problems. By turning multi-select off and changing the focus to a different cell before calling clear() I was able to fix the problem.Does anyone have any ideas as to what might be causing this problem? Header Text; switch (header Text) { case "Number": if (!

2) Detach the event hander before the unwanted event triggers and re-attach after. so when i click the add button the cell validating event triggers i have posted the cell validating event do you know how to solve this thanxxx code!!!
