hi
i wanted to build a print button in asp.net 2.0

i wrote the following code

"codebehind"

<br />
<br />
 protected void Button1_Click(object sender, EventArgs e)<br />
    {<br />
        Button1.Attributes.Add("onClick","window.print()");<br />
        Button1.Visible = false;<br />
<br />
    }

now.. the button does disappear, but the print window doesnt come up.

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.

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:
<head runat="server">
<title>Your page name here</title>
<script type="text/javascript" >
function doPrint(button)
{
button.style.visibility = "hidden";
window.print();
return false;
}
</script>
</head>

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.

Why don't you comment the first line and uncomment the commented line ? I don't think that HTML input hidden field is having innerText Property ! Confused | :confused:

My suggestion is make the HidTemp to runat server. Then you can easily get the value on server side.

I think this will work only on IE... Confused | :confused:

Hi all,

I have a web page, where user can delete a record. I need to show a confirmation message and while googling i got the following code...

<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return confirm('Are you sure you want to delete this record?');" OnClick="Button1_Click1" />

protected void Page_Load(object sender, EventArgs e)
{
Button1.Attributes.Add("onclick", "return confirm(\'Are you sure you want to delete this record?\');");
}

This works fine, but i don't know how to track the user response. When user hits No, i should be able track "false". Please tell me how to achive this..

Thanks in advance

Sebastian

{
Button1.Attributes.Add("onclick", "return confirm(\'Are you sure you want to delete this record?\');");
}

The parts bolded above essentially do the same thing. I would suggest you stick with the OnClientClick one.

Basically by saying "return confirm('...')" in the clientside click event, if the user clicks "cancel" then the server postback will not occur. Therefore all you need to do is handle the server side click as the action to take when the user wishes to delete and you can rest assure that if they do click cancel than the server side handler will not be entered.
