Hello,
I'm using a datagridview in my ASP.NET project.It has 5 colums which one of them has line number from 1 to 10 and others have checkboxes.If A user selects a checkbox from any column and later changes his idea and select new one without unchecking previous selection before pressing save button ; first selection must be empty or a message warns user which says “ there is already selected one ”.

How will I do this ?

Thanks in advance

If you want to have only one selection then use radio buttons instead of checkboxes

Solution 1

You can use grid cell validating event to check that 'already a checkbox is selected'.

Solution 2

Using radio button is better if you just want user to select single row.
