Event Subscription:

this.textBox1.Validating += new System.ComponentModel.CancelEventHandler(this.myEm ptyTextBox_Validating);

Event Handler:
private void myEmptyTextBox_Validating(object sender, System.ComponentModel.CancelEventArgs e){ }

Can someone tell me what, if anything will be passed to the event handler's second parameter , e ?

Hi Mark

Go to this article in your .net documentation.

ms-help://MS.VSCC/MS.MSDNVS/cpref/html/frlrfsystemcomponentmodelcanceleventargsclasstopic .htm

If the links dont map correctly, simply look for CancelEventArgs Class help topics.

Hope this will help you.
