Techsatish,

From what I understand you have inherited some control and you want to make
the control not to react on double click.

It depends on the base control implementation, but you may try adding to
your constructor the following line of code:

SetStyle(ControlStyles.StandardDoubleClick, false);

The control won't fire DoubleClick event, but I really doubt it will help.

You can actually use the same event handler for both events.

In VB, assuming your single click event looks someting like this:
Private Sub MyControl_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyControl.Click

You can change it to something like:
Private Sub MyControl_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyControl.Click, MyControl.DoubleClick

In C#, I think you would need to use the Add Handler statement to add the
click event handler to the double click event). (I don't use C#, though, so
this is probably wrong in some way.)
