Data Grid View Cell Validating Event Args) Handles Data Grid View1. The following code example handles the Cell Validating event to ensure that only positive integers are entered by the user. Error Text = "" Dim new Integer As Integer ' Don't try to validate the 'new row' until finished ' editing since there ' is not any point in validating its initial value. string to a cell, the Cell Error Text Changed event of the Data Grid View control is raised. I can tab to the next cell and the code is not called, then tab back back to the cell (that has the validating), then tab to the next cell and this time it does call the code. There is an e.cancel property that when it is set to true is suppose to keep the focus in the cell but if the code is not invoked what good is that?This example is part of a larger example available in [How to: Validate Data in the Windows Forms Data Grid View Control](~/docs/framework/winforms/controls/ Net 2008 and trying to validate a certain cell with certain values like: In Data Grid View1 i want to check the entered data in column 1 and cell 1 if it's less than 10 or not so i used the following code Private Sub Data Grid View1_Cell Validating(By Val sender As Object, By Val e As System. I am currently using the Cell Validating event to prevent the cell from updating its value but I'm not able to exit the editing mode.The cell is then waiting for a correct value and won't let the user to simply cancel&revert his action...

The following code example illustrates the use of this property. Data Grid View Cell Validating Event Args) Handles dg Checks. Must be a numeric value to continue." End If Case "Date Cleared" If Date. I was checking the value of the Cell before it was ever sent to the Cell. All I need now is a little assistance in getting the dg. Private Sub dg Checks_Cell Validating(By Val sender As Object, By Val e As System. Cell Validating Dim Cell As Data Grid View Cell = Nothing Dim Val Date As Date = Nothing Dim Val Long As Long = 0 txt Msg.


I thing that the cell validating event validates the cell it self...
