how can I talk to the live form at design time? For example, here is the property I am modifying on an inherited TextBox: I need to pass the name of the form at design time so the custom UITypeEditor has the name to get the correct data to return to the UITypeEditor in the property. <CategoryAttribute("Design"), _ DefaultValueAttribute(GetType(String), ""), _ DescriptionAttribute("Name of the data field."), _ Editor(GetType(MergeFieldNameBuilder), GetType(System.Drawing.Design.UITypeEditor))> _ Public Property DataField() As String Get Return _DataField End Get Set(ByVal value As String) _DataField = value End Set End Property Show quoteHide quote "Jack Jackson" <jjackson-***@cinnovations.net> wrote in message news:qv0p25tm7q3nvbg9t6q1kqqlak6a5f22bk@4ax.com... > On Sun, 7 Jun 2009 17:37:59 -0700, "Derek Hart" <derekmh***@yahoo.com> > wrote: > >>Build a usercontrol that I want developers to use in Visual Studio.

I think I have found something that puts me on the right track. This will
give me the name of the form inside the property: Return Site.Container.Components(0).Site.Name I can even get to the properties with correct casting. Return CType(Site.Container.Components(0), System.Windows.Forms.Form).Text Any comments on if this is the best way to get to properties at design time?

I still don't see why you don't just use (in some method in your UserControl) Me.FindForm() or use Me.Parent to back up through the parents of your UserControl until you get to the form. Even in the IDE, each control is added to its parent's Controls collection, so starting with any control you can look through the tree of all controls.

I have a class that just inherits a control. Just for testing, I placed the CType down below. This class is not part of a usercontrol directly. It is just a textbox that is used inside the IDE toolbox. In the "Get" part of the property I tried looking at the parent, but I don't really have access to this.

If you want the Get of the DataField property to return the form's Text property, I would try: Get Dim frm As System.Windows.Forms.Form = Me.FindForm() Return If(frm Is Nothing, '', frm.Text) End Get Show quoteHide quote On Tue, 9 Jun 2009 18:52:05 -0700, "Derek Hart" <derekmh***@yahoo.com> wrote: >Jack, > >I have a class that just inherits a control.
