Property Grid Custom Editor

Question

I have a custom form Names "Form1" that I want to open through propertygrid control.

Code here

[CategoryAttribute("Extended Properties"),
        EditorAttribute(typeof(System.Windows.Forms.Form1), typeof(System.Drawing.Design.UITypeEditor))]
        [TypeConverter(typeof(ExpandableObjectConverter))]
        public string Path { get; set; }

Answer 1

You need to define a class that inherits from UITypeEditor who's job will be to display Form1. This type is what goes into the EditorAttribute (not Form1). The sample here is more or less what you need to implement. Basically, you override GetEditorStyle to return UITypeEditorEditStyle.Modal and override EditValue to call IWindowsFormsEditorService.ShowDialog on an instance of your form.
