Say you need capture an event for a control in a User Control and you are not permitted to change the control itself.

You can hook into control events, even for private controls with this code:

//In a Windows Form

//Get the private control cboSomePrivateControl from the user control's Control collection
ComboBox cbo = (customUserControl.Controls["cboSomePrivateControl"] as ComboBox);
 
//Hook  control change and assign a method
cbo.SelectedIndexChange += new EventHandler(cbo_SelectionChange);
 
...
 
//create the method to handle the change.
void cbo_SelectionChange(object sender, EventArgs e)
{
 
}
