如何检查控件是否为按钮？

Question

How can I check that whether mouse pointer is pointing a button or some other control? I want to perform a particular task when mouse hover/move a button.

I know I can set event on individual button. But isn't it possible to check the pointed/hover control is button?

Answer 1

The sender argument in an event method should have the information you need...

private void MyEventHandler(object sender, EventArgs args) {
   if(sender is Button) {
      //Do some stuff
   }
}

Answer 2

I'm not sure if you mean: can I do this without event handlers for MouseHover in individual controls. If so, the answer is no.

But you can attach each contol's MouseHover event to just one event handler that could look like the one in Chris's answer. For convenience you could even do that programmatically by looping through the controls in the form's load event. (assuming this is winforms)
