Print? I guess you mean print on the screen?

Did you check the HttpContext.Current.Response object?

hi,
no i have not used HttpContext.current......
If i use that, will it be possible to print the contents of text box in the sameway as i entered into the text box. Can u please explain me briefly how to use that..
thanks

Hi :=)

Do you want to change the screen during typeing the text in the textbox?
You have to notice that the scripts you write (in the code-behind-page or in the page itself) are serverside executed. Which means that you have to implement some kind of redirection. The redirection has been standarized within the textbox by means of the autopostback option. This, in combination with the TextChange() event is a worse combination because after each keypress the page will be posted back.....
The LostFocus() event gives a much better performance on this but the page still have to make a roundtrip to the server in able to execute the scripts.....

What exactly are you trying to acchieve?

This code should manage your printing with asp.net. It's a piece of javascript;)

<script type="text/javascript">
<!--
function printTextBox_Text(elementId)
{
 var textboxText = document.getElementById(elementId);
 var windowUrl = 'about:blank';
 var windowName = 'Print' + new Date().getTime();
 var printWindow = window.open(windowUrl, windowName, 'left=50000,top=50000,width=0,height=0');

 printWindow.document.write(textboxText .value);
 printWindow.document.close();
 printWindow.focus();
 printWindow.print();
 printWindow.close();
}
// -->
</script>

I've worked it out to an example for you....

Place 1 textbox control on your page, make it multiline and insert the below stated code in the code-behind page.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim sPrintScript As System.Text.StringBuilder = New System.Text.StringBuilder
        sPrintScript.Append("<script type='text/javascript'>").AppendLine("")
        sPrintScript.Append("<!--").AppendLine("")
        sPrintScript.Append("function printText(elementId)").AppendLine("")
        sPrintScript.Append("{").AppendLine("")
        sPrintScript.Append("var printContent = document.getElementById(elementId);").AppendLine("")
        sPrintScript.Append("var windowUrl = 'about:blank';").AppendLine("")
        sPrintScript.Append("var windowName = 'Print' + new Date().getTime();").AppendLine("")
        sPrintScript.Append("var sTextToPrint = printContent.innerHTML;").AppendLine("")
        sPrintScript.Append("var printWindow = window.open(windowUrl, windowName, 'left=50000,top=50000,width=0,height=0');")
        sPrintScript.AppendLine("")
        sPrintScript.Append("printWindow.document.write(sTextToPrint);").AppendLine("")
        sPrintScript.Append("printWindow.document.close();").AppendLine("")
        sPrintScript.Append("printWindow.focus();").AppendLine("")
        sPrintScript.Append("printWindow.print();").AppendLine("")
        sPrintScript.Append("printWindow.close();").AppendLine("").Append("}").AppendLine("")
        sPrintScript.Append("// -->").AppendLine("")
        sPrintScript.Append("</script>")
        If Not ClientScript.IsClientScriptBlockRegistered("printText") Then _
        ClientScript.RegisterClientScriptBlock(Me.GetType(), "printText", sPrintScript.ToString)
        Button1.Attributes.Add("onclick", String.Format("return printText('{0}');", Me.TextBox1.ClientID))
    End Sub

the solution is simple, just open a new window with the content of that textbox using javascript.
