print button.

[Kunal P]

hi i wanted to build a print button in asp.net 2.0 i wrote the following code "codebehind" protected void Button1_Click(object sender, EventArgs e) { Button1.Attributes.Add("onClick","window.print()"); Button1.Visible = false; } now.. the button does disappear, but the print window doesnt come up. please help.. and i dont want a html input button.

For this code to work you need to add the attributes before the button is clicked. So on the page load event do if (!IsPostback) { Button1.Attributes.Add("onClick","window.print()"); } Then it should work like you want it to. Hope that helps. Ben

the thing worked, but theer`s a little problem. i want the button to go invisible, so that when the printing is done, the button does not show up. right now as i click the button, the print window comes, and then the button goes invisible.

You might want to get rid of the codebehind and do something like this: Change this line: Button1.Attributes.Add("onClick","window.print()"); to: Button1.Attributes.Add("onClick","document.getElementById("+Button1.ClientId+").style.visibility = 'hidden';window.print();"); I think that should work for you.

did get rid of the codebehind, removed the defintion for "Button1_Click". and placed the following code in the page_load event if (!IsPostBack) { Button1.Attributes.Add("onClick", "document.getElementById(" + Button1.ClientID + ").style.visibility = 'hidden';window.print();"); } but nothing seems to happen at all. nor does the button disappear, and neither does the print window come up

Ok I did a little playing. It looks like you will need to create a javascript funciton. In the header section of your html page you need this function: Your page name here function doPrint(button) { button.style.visibility = "hidden"; window.print(); return false; } Then in the page load event do this: Button1.Attributes.Add("onClick", "return doPrint(" + Button1.ClientID + ");"); That will work. NOTE as soon as your page posts back to the server the print button will show up again. Hope that helps. Ben
