Recently I had developed a user control by inheriting the Textbox in which I have just added 1 property "isValidate" whose data type is boolean. Now the problem I am facing is, when I write "this.ActiveControl" I cannot see the "isValidate" property as the "Control" class does not posess the "isValidate" property. So, any idea how to manage this problem?

Thanks in advance

How come, if you added it? "Cannot see" — where? If you really added it (what is the access modifier?), it's there.
Anyway, how are we supposed to find your bug without adequate code sample?

That's easy. Let's assume your control class name is MyTextBox. Now you do this

C#

MyTextBox txtBox = this.ActiveControl as MyTextBox;
if (txtBox != null)
{
  //Bingo, the active control is MyTextBox
  //Accessing IsValidate property
  txtBox.IsValidate = false;
}

Of course, make sure your property is public.
