Controlling the controls a validator validates


I want to control which controls appear for a validator when they go to controltovalidate dropdown in property grid.  Is the solution to create a designer for the control?  How do you regulate that?  I can't override the ControlToValidate property...

Boy Brian, you have been rewriting validation for a while now. You already know that I already did all of this, so let me give you a hint here.

While you cannot override ControlToValidate, you can create a ControlDesigner class that defines the PreFilterProperties() method. That method is allowed to insert or replace any attribute attached to the property, such as the EditorAttribute. I'm sure there are numerous examples on the web of using this property.

I was thinking that might be the solution, but wasn't sure if there was an easier way.  Thank you for the help.

Creating a User Control validator that validates a control on the page, rather than inside the control.
I'm trying to create a custom user control that is nothing more than a RangeValidator that validates other controls that lie on the page rather than inside the control itself... is this possible, is there a way to "bubble" it up. Thanks, G My answer to your other question regarding the CompareValidator applies here. If the custom control is in the same naming container AND does not implement INamingContainer, you can create a property that lets the user assign the control to validate. Internally assign the Validator.ControlToValidate property to the value of that property.-...
