Trigger cellvalidating event

The validation events are meant to support the data validation of the user input.

They occur when the new content entered by the user is about to be committed.

They do not occur when the Rad Grid View loads data.

The Cell Validating event occurs always before the Cell Validated event when the edited cell is about to lose its focus.

When you click a Check Box in a Data Grid View Check Box Column, the check marker will update immediately, but Cell Value Changed event on the Data Grid View will not fire until the user happens to click elsewhere and the cell has lost focus. Well, the Data Grid View thinks it’s a little preemptive to go declaring that the cell value has changed while you are still selected on it.

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.

To commit the change when the cell is clicked, you must handle the Data Grid View Commit Edit method and pass in the Commit value.

Rows in the control are not automatically sorted when a cell value is changed.
