Custom Control Property (list)

Question

I've created this Inherited (textbox) Custom control. I'm want to provide a property "Validating Type" that has a dropdown list of possible values Such as Alpha AlphaNumeric Whole Numbers Numbers with decimal I know how to create properties with using get and set. I've already implemented several properties. But can't figure out how to provide a dropdown list to allow for choosing from a list of possible values.

Ok...answered my own question. For anyone that's interested. This is how you define (well..at least one way) for a Property in a custom control so that you see mulitple values via a dropdown list in your property browser at design time private InputTextType _inputTextType; public enum InputTextType { Alpha AlphaNumeric DigitsOnly DigitsWithDecimal Email } [Description(Type of Text to expect from user input) Category(Misc)] public InputTextType InputType { get {return _inputTextType;} set {_inputTextType = value;} }

Maybe this will make it more clear. Here's an example. In this custom control I developed I've implemented a property callled InputRequired Private Boolean _inputRequired; public Boolean InputRequired { get { return _nputRequired;} set { _inputRequired = value;} } When I drag this control onto my form and look that properties list there's a InputRequired property with a dropdown avaliable that has True and False. That's what I'm looking for but want to specify a list of values for this other property. This other property I want to create is for the purposes of validation. If I set the property to Alpha then at runtime my code knows that ONLY alpha text can be entered into this textbox. If not I can throw up a message box to the user. If the propetry is set to AlhapNumeric at runtime the code knows that alphanumeric text can be entered. And process the entered text accordingly. Follow...?

Huh?? I'm not following. I'm trying to create a property within a custom control I developed. For the other properties I've implemented I've just declared a private memeber and then have pulblic get and set methods for each private members. Works fine. After I've added the control to my toolbox and then drag the custom textbox onto a form all the properties of the textbox AND the new properties I've defined show up in the properties list. What I want to do is to create a another property for this textbox but instead of just being able to set one value for the property I want to allow for multiple choices. Hence..the dropdown list I refered to

Or ComboBox.

Wouldn't it be easier to use the DomainUpDown (or NumericUpDown) classes?
