Windows.Forms Binding errors with .Net 2.0 (Part 2)

03 January 2008 22:05 by Riaan Lehmkuhl
Hi, this is number two of my Binding error series.

I've got a BindingSource setup with the Sort property set to a valid column name and all works well, (dejavu) but the problem is when the form closes, and starts Disposing controls, I get this message:
"Sort string contains a property that is not in the IBindingList."

The solution is almost the same as in Part 1, but this time we want to clear the Sort property of all BindingSources on the form...
/// <summary> /// Clean up any resources being used. /// </summary> /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param> protected override void Dispose(bool disposing) {    try {       if (disposing && (null != components)) {          foreach (System.ComponentModel.IComponent comp in components.Components) {             if (comp is System.Windows.Forms.BindingSource)                (comp as System.Windows.Forms.BindingSource).Sort = null;          }          components.Dispose();       }    } finally {       base.Dispose(disposing);    } }

Notice the bit where we loop through the components to be disposed of. Now Isn't this fun!
