Row Validating Dim row As Data Grid View Row = _ songs Data Grid View. Row Index) Dim track Cell As Data Grid View Cell = _ row. Cancel = Not (Is Track Good(track Cell) _ And Also Is Date Good(date Cell)) End Sub Private Function Is Track Good(By Ref cell As Data Grid View Cell) As Boolean If cell. The following code example illustrates how to handle this event to clear the row Data Grid View Row. Error Text property in case it was previously set by a Cell Validating event handler. Error Text = _ "Invalid format" Return False End Try End If Return True End Function This event is analogous to the Control. Use this event to perform validation on all the values of a row.column, its value is tested for validity by checking that it is not empty. You have two options for fixing this - one is to simply use the row's error text so instead of: The other option is to change the cell padding of the cell (moving the editing control) and painting the icon in.I actually found this technique for solving the problem here and reproduced their code below (in C# and not VB. First you have your cell validating event where you add some code to change the cell padding: The post where I found this neglects to set the mouse over for the new painted icon - Here is some rough code that addresses that, I don't have time to get it really working so there are some slight fudges that thought would fix - I'll tidy that up if I get a minute later. Show Cell Tool Tips = true and introduce a boolean in Error to track if we currently have an editing error.
Error Text = _ "A Track must be a number" Return False End If Return True End Function Private Function Is Date Good(By Ref cell As Data Grid View Cell) As Boolean If cell.
The Cell Validating event handler can clear the error text when the new cell value meets the validation criteria, but when the user reverts to the old cell value by pressing ESC, the Cell Validating event does not occur.
This example is part of a larger example available in Walkthrough: Validating Data in the Windows Forms Data Grid View Control.
Cell Value Changed event occurs when the user-specified value is committed, which typically occurs when focus leaves the cell.
