Need id of calling object

[lunchbox88]

C#

I have a form with 2 textboxes. I want to add a button by each text box to count the characters. I can do this the really easy way by creating 2 buttons, and coding an OnClick for each button. I'd rather check to see which button is clicked, and count the characters in the appropriate textbox.

How can I get the ID of the button that was clicked?

Thanks!

Hi,
When u click on Button,U will get Button click event.That button click event has first parameter as Sender of type Object.Sender specifies the source of the object whic raises this click event.
Hope this helps to You

I know I can use that object, but I'm not sure how to get the name of the object.

I know that GetType will return System.Web.UI.WebControls.Button, but I'm not sure how to get the name/ID of the button.

Thanks

Simply create an event that handles both of the Button's Click event and then use the sender object to get a reference to the Button and it's ID/Name.

Ok, that's what I said I wanted to do, but I'm not sure HOW to do it. How do I get the button ID/Name?

If you re-read the above, it should be fairly self-explanatory e.g.

    Private Sub Button1_Click(ByVal sender As System.Object, _
      ByVal e As System.EventArgs) Handles Button1.Click, Button2.Click
       Dim btn as New Button
       btn = Ctype(sender, Button)
       ' Do whatever you want with the Button here...
    End Sub
