.NET Forum / Windows Forms / Design Time / October 2007Get the ExternaProvider Control Refrence in the UITypeEditor
Dear Sir I created a control "MyControl" that implements the IExternalProvider Class, "MyControl" should provide the property MyProperty for all other controls. I created also an UITypeEditor class that help the user to select "MyProperty1" form a DropDownList My Problem is I need to get a reference for MyControl in the EditValue method of the UITypeEditor because the DropDownList changes according to other property "MyProperty2" of "MyControl". My class code like this: public class MyControl : UserControl, System.ComponentModel.IExtenderProvider { …… public string MyProperty2 { …. } [Editor(typeof(SaudisoftMyProperty1Editor), typeof(UITypeEditor)), DefaultValue("")] public string GetMyProperty1(Control control) { …… } …… public class MyProperty1Editor : UITypeEditor { …. public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value) { …… MyControl sd =? //here I want to get MyControl String M=sd.MyPropery2 …… return value; } ……. } …… } public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value) { if(context == null || context.Instance == null || provider == null) return value; .... MyControl ctrl = context.Instance as MyControl; if(ctrl == null) return null; .... } Thanks for replay I think you didn't got what I mean, context.Instance returns the reference of the current selected control, I need a reference for MyControl (Extender Provider) the control that provided the property the user currently editing. best regards, Ahmed public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value) { if(context == null || context.Instance == null || provider == null) return value; .... MyControl ctrl = context.Instance as MyControl; if(ctrl == null) return null; .... } I found it, ExtenderProvidedPropertyAttribute EPPA = context.PropertyDescriptor.Attributes[typeof(ExtenderProvidedPropertyAttribute)] as ExtenderProvidedPropertyAttribute; MyControl sd = (MyControl)EPPA.Provider; thanks Ahmed Thanks for replay I think you didn't got what I mean, context.Instance returns the reference of the current selected control, I need a reference for MyControl (Extender Provider) the control that provided the property the user currently editing. best regards, Ahmed "Roger Stewart" <rstewart27104@gmail.com> wrote in message news:1190901166.196448.183890@r29g2000hsg.googlegroups.com... public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value) { if(context == null || context.Instance == null || provider == null) return value; ....
