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.
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.
I've tried a few things and have searched for answers without luck so far.
In general, it is better to use the Cell Parsing event whenever you need to convert/change the value in a cell.
I would like to manipulate a cell in my Data Grid View when it is validating so that if the user enters a value that is not valid for the database, but is easily converted to valid data, the program will change the value to an appropriate one.
I am able to validate my value properly but when I try to change it to something valid I get a Data Error. You should never attempt to change the cell value in the handler for this event, because unless you cancel the event (in which case the user is stuck in edit mode), the cell value is set to the value from the editing control immediately after the event finishes.
Since you have not added your new row yet it should validate OK.
Or if not, then it is because the user has entered an invalid value in the current cell. 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.
Steps: Private Sub Data Grid View1_Cell Validating(By Val sender As System.
Is In Edit Mode Then Dim c As Control = Data Grid View1.
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!!!
