Cellvalidating at datagridview

What's the best place to implement validation logic code and conditional formatting code for a Data Grid View?

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.

There are two ways to manage unwanted execution of event handlers. Data Grid View Cell Validating Event Args' does not contain a constructor that takes '1' arguments" what is the solution for this???????

1) Add a conditional statement in the event handler code to only execute when required. Cell Validating -= new Data Grid View Cell Validating Event Args(dgv Sub Contractor_Cell Validating); it says that "Error 7 'System. hey what do ouy mena by the below private void data Grid View1_Cell Validating(object sender, Data Grid View Cell Validating Event Args e) if (adding Row) - is to call the button event for adding a new row is it every time the cell validating event triggers and a value is entered in the datagridview cell right??

What I really want is some flavour of End Edit() that behaves just like pressing enter on the last row of a grid with adding disabled. my version is a slight different from yours, because when i move to the other cell, and my code returns e.cancel=false in the cell validating event, an error will be generated, says that: "operation did not succeed, because the program cannot commit or quit a cell value change". this is my code: Protected Overrides Function Process Dialog Key(By Val key Data As System.

Cells(1) frm Ok_Click(Me, New Event Args) Catch ex As Exception End Try Return True End If End If Return My Base.

I have two Data Grid View Textbox Column in my Form.

I want to compare one textbox with another textbox value.

1) Add a conditional statement in the event handler code to only execute when required.

2) Detach the event hander before the unwanted event triggers and re-attach after.

Currently, I'm just manually calling my validation logic before I call End Edit, but it seems like I'm missing something.
