Pass Variable At Design Time

[Derek Hart]

I have a custom control with a property defined as follows. The UITypeEditor
is a Windows Form called MergeFieldNameBuilder. How do I pass a variable to
this form from this property? Cannot figure out how to set a global variable
from here, or some other way to pass it in.

<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

The type editor can access any public method property in your class to edit
by accessing/typecasting the value parameter of the type editor EditValue
method e.g.

public class StringListTypeEditor : UITypeEditor
{
// Methods
public override object EditValue(ITypeDescriptorContext context,
IServiceProvider provider, object value)
{
object dResult = null;
if (((context != null) && (context.Instance != null)) && (provider !=
null))
{
IWindowsFormsEditorService edSvc =
provider.GetService(typeof(IWindowsFormsEditorService)) as
IWindowsFormsEditorService;
if (edSvc == null)
{
return dResult;
}
StringListEditor dEdit = new StringListEditor();
CaptionsList dVal = (CaptionsList) value; //<=== your object giving all
methods and properties
......

You can keep the variable you want to pass as a member of the class defining
the DataField property. One of your MergeFieldNameBuilder overriden methods
will get pased an instance of the class, from which you can access the
variable.
