问题 I have a custom control on a form. Basically my Visual Studio has been fubared for the past 5 hours because my properties are loading at initialization. The code: this.customControl.customProp = ((System.Collections.Generic.List<customType>)(resources.GetObject("customControl.customProp"))); What I would like to know is where this code is actually being executed at or is it storing these pieces of data somewhere?
