how can i create requiredFieldValidator via code-behind?

trevoray used Ask the Experts™
hi, previous someone gave me the following answer for creating a validator for field behind. it worked, but it wasn't the validator i needed. i tried to reformat it for mine and i can't get it to work. i'll post previous answer first, and then my retooling. can anyone help me how to retool this to make it a RequiredFieldValidator? thanks!

             I believe dummy field could create problems (cause validator will try to check that dummy)

anyways, there is a better way..

put a dummy LABEL to form (i.e. under textbox) .. and try this;


Dim myCompare As CompareValidator = New CompareValidator

        With myCompare
            .ControlToValidate = "TextBox1"         '
            .ErrorMessage = "Numbers Only"
            .Display = ValidatorDisplay.Dynamic
            .Operator = ValidationCompareOperator.DataTypeCheck
            .Type = ValidationDataType.Integer
            .EnableClientScript = True
        End With



this is creating a datatypecheck validator via behind-code. you can create any validator when ever you need with this way.


My "re-tooling" to get it to work for RequiredFieldValidator, which hasn't worked yet.

Dim myRequired1 As RequiredFieldValidator = New RequiredFieldValidator
                With myRequired1
                    .ControlToValidate = "pub1"
                    .ErrorMessage = "Publication #1"
                    .Display = ValidatorDisplay.Dynamic
                    .Text = "Please provide publication."
                End With

- Used your code
- PubDummy is a label
- Left the textbox empty
- Added and pressed a button to cause a postback
