Question

This is some old code that I am not too familiar with :

 RequiredFieldValidator vldRequired = new RequiredFieldValidator();
                    vldRequired.Display = ValidatorDisplay.Dynamic;
                    vldRequired.Text = "*";
                    vldRequired.ControlToValidate = "txtSetting";
                    vldRequired.ID = "vldRequired";
                    vldRequired.Enabled = true;
                    vldRequired.ErrorMessage = SettingTitle + " is required";
                    returnCell.Controls.Add(vldRequired);

Where, IF you tab passed a required field the * will show up next to it. THE ErrorMessage only shows up when a Submit is clicked (that is all fine).

However, once you fill in the required field and tab out of the input, the “*” goes away but the ErrorMessage stays — I cannot figure out how to make that ErrorMessage go away when the * does.

Help?

Ok, I just ran into a similar issue on one of my projects. It’s been a while since I’ve used the requiredFieldValidator. Try removing your Text Property as it interferes with the Error Message. Also ensure that you don’t have a Validation Summary on the page as that may cause fixed messages to linger in front of the user even though they have corrected the the problem on the client side.

RequiredFieldValidator vldRequired = new RequiredFieldValidator();
                    vldRequired.Display = ValidatorDisplay.Dynamic;
                    //vldRequired.Text = "*";
                    vldRequired.ControlToValidate = "txtSetting";
                    vldRequired.ID = "vldRequired";
                    vldRequired.Enabled = true;
                    vldRequired.ErrorMessage = SettingTitle + " is required";
                    returnCell.Controls.Add(vldRequired);
