clicking twice for dialog box [RESOLVED]

I'm using this code on the click event to open a print dialog box..
The problem I'm having is, you have to click the button twice before the dialog box will show....Any suggestions?

Private Sub btnPrint_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrint.Click
btnPrint.Attributes.Add("onclick", "javaScript:window.print()")
End Sub

you have to do it twice cuz you that attribute isn't added until you click it one. After you click it once then it's added, now you have to click it again then it works. Add the attribute in the Page_Load:

VB Code:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    PrintDialog.Attributes.Add("onClick", "window.print()")
End Sub

Question though, why use a server side control for this, why not just use a regular ol' button? just curious

thanks pvb, that worked.

If I used an HTML button, would that be quicker becasue I wouldn't have to postback?

not sure if it would be noticably faster but it would save you an unneccessary postback.
