ControlToValidate - CheckBoxList

Hello

I have created a CheckBoxList validator which ensure that the max and min #=
of items have been checked.
Everything works properly, but I would like to be able to select a CheckBox=
List within the ControlToValidate section in the VS.Net properties window. =
Currently, the list that is displayed will only show TextBox's, ListBoxes, =
..., but not CheckBoxList.

I assume this is inherrited from the System.Web.UI.WebControls.BaseValidato=
r class, so does anyone know how to override this feature so that it shows =
CheckBoxLists?

Thanks,

you'll have to change the UITypeEditor for that property.
I believe it's the Editor attribute applied to the propety.

you could probably inherit from the one the current UITypeEditor to do =
it.

Hey Andy

Thanks for getting back to me.=20
Would you be able to elaborate more on the type that I should be using?

Within my class, I now have the following code...

[Editor(typeof(System.Web.UI.WebControls.CheckBoxList), typeof(System.Drawi=
ng.Design.UITypeEditor))]=20
public string ControlToValidate{
    get{return this.ControlToValidate;}
    set{base.ControlToValidate =3D value;}
}

* Note, I am extending the BaseValidator class

Which throws an exception within VS.Net (Didn't think the CheckBoxList was =
correct, but thought I would try)
Do you know the proper values to place into the Editor section or where I c=
ould find/figure these out?

Thanks,

hi,
the solution is much simpler. you just have to add the
ValidationPropertyAttribute attribute to your class:

    [
    DefaultProperty("Text"),
    ValidationPropertyAttribute("Text")
    ]
    public class EnhLabelEdit : WebControl, IPostBackDataHandler
    {

    }
and yep, I agree, it was not easy to find...
John.
