Hello Guys,

I am using from the demos the code to validate a control within the grid and it works well.  I had to add a few additional lines to validate more than one control, and I wonder whether you would review it and tell me whether there is a better way to do it, or if this is optimum.

Thanks a lot, here is the code that works but may need improving.  You can see that I have taken the demo code and then added editor2, cell2, validator2 etc

            if (e.Item is GridEditableItem && e.Item.IsInEditMode) 
                GridEditableItem item = e.Item as GridEditableItem; 
                GridTextBoxColumnEditor editor = (GridTextBoxColumnEditor)item.EditManager.GetColumnEditor("PersonId"); 
                TableCell cell = (TableCell)editor.TextBoxControl.Parent; 
                RequiredFieldValidator validator = new RequiredFieldValidator(); 
                editor.TextBoxControl.ID = "ID_for_validation"
                validator.ControlToValidate = editor.TextBoxControl.ID; 
                validator.ErrorMessage = "You must enter a PersonId"
                GridTextBoxColumnEditor editor2 = (GridTextBoxColumnEditor)item.EditManager.GetColumnEditor("ContactWhere"); 
                TableCell cell2 = (TableCell)editor2.TextBoxControl.Parent; 
                RequiredFieldValidator validator2 = new RequiredFieldValidator(); 
                editor2.TextBoxControl.ID = "ID_for_validation2"
                validator2.ControlToValidate = editor2.TextBoxControl.ID; 
                validator2.ErrorMessage = "You must enter a H, C or M"

Thanks in advance for any comments you wish to make,

Hi Mark,

Your approach is completely valid and correct. The only thing you might consider is using the editor.ContainerControl property to access the table cell and add the validator control: editor.ContainerControl.Controls.Add(validator). However, it is equivalent to the code you have implemented with the only difference of saving you a few casts.

Hope this information helps.
