provides a convenient way to realize data validation before it is committed to the underlying data source.
SOLUTION To achieve data validation prior the row is committed, you can handle the Cell Validating event, which is raised by the control when the current cell changes or when it goes out of edit mode.
How can I disable the cell validating event for the rows that was added before???
thankxxxxxx There are two ways to manage unwanted execution of event handlers.
Something there is causing the cell validating event to fire. [Edit] The validating event is firing because focus is being moved from the DGV to the button.
Canceling this event prevents the user from exiting the cell until a valid value is entered or the edit process is canceled (via Esc key).
The Data Bound Item will be updated only if the cell is validated.
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??
