The Row Validating event can be used the same way to prevent the user from exiting the current row.
However, the editor will be closed in this case and the value will be committed to the underlying data source.
To get pass the cell validation need to enter the valid input to the cell. Current Cell Validated event triggered when the cell has finished validating with valid data.
I want my users to enter some data into a bound Data Grid View (dgv) and when done to have the program fill in some columns (hidden key) and to populate some cells in the same row according to the data entered - like max of several cells.
Use this event to perform validation on all the values of a row.
In case of invalid data, error icon is displayed at the top right corner of Grid Cell.
Can I use Data Grid View Row Validating to update cells? What would be the correct way for me to fill in hidden key information and to calculate some cell values?
Validated events from occurring, and also prevents the user from leaving the invalid row and prevents the row from being saved to an external data source in data bound mode.
It will show an error indicator at the row header when you set this property to a non empty string.
The code snippet below demonstrates simple data validation scenario.
