Using CellEditEnding for Validation
You'll want to do some kind of real validation instead of just making sure the box doesn't contain a period, but it's easy to cancel invalid input from being entered into the datagrid:
private void myGrid_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
{
var dataEntered = ((TextBox)e.EditingElement).Text;
if (!ValidData(dataEntered))
{
e.Cancel = true;
MessageBox.Show("Invalid data entered. Cancelling.");
return;
}
MessageBox.Show("Valid Data Entered.");
}
private bool ValidData(string dataEntered)
{
if (dataEntered.Contains('.'))
{
return false;
}
return true;
}
