Cellvalidating datagridview in c net


To perform any custom validation on the cell or row being edited, you can use the Cell Validating and Row Validation events, respectively.

If you want to validate the data cell by cell, the former event is useful where you want to validate the data for the entire row at once then the later event is handy.

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.

The Data Grid View control of Windows Forms is a versatile control that can help you create professional-looking data entry forms.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 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.

How can I disable the cell validating event for the rows that was added before???
