How difficult can it be?

I'm trying to do something that I feel should be very simple but can't find a simple answer!

I have an ASP.net page that has a text box and a button. The user is to put some text in the box and click the button (told you it was simple

)

What I then want is for a NEW browser window to open and show a URL that is partially dependent on the contents of the text box. I know about response.redirect but that opens in the same window.

Is there not some simple .net code that can do this? Do I need to delve into Javascript?

thanks

steve

The key is the "target" attribute of the form element on that page. Set target="_blank" and post backs will open up in a new window; from there, you can redirect to wherever you need.

For example:


<form id="Form1" method="post" runat="server" target="_blank">
    <asp:TextBox id="TextBox1" runat="server/>
    <asp:Button id="Button1" runat="server" Text="Search Google"/>
</form>

and in the code-behind:


    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Response.Redirect("http://www.google.com/search?q=" & Server.UrlEncode(TextBox1.Text))
    End Sub

You need to use javascript to do that. You need to use the window.open function.


if(document.getElementById)
   window.onload = OnLoad;

function OnLoad()
{
   if(document.getElementById("<The ID of your button>") != null)
       document.getElementById("<The ID of your button>").click = openNewWindow;
}

function openNewWindow()
{
   window.open("http://someplace/somepage.aspx?TextBox=" + document.getElementById("<The ID of your textbox>").value);
   return false;
}

End Sub

Thats a good solution, it will work even when javascript is disabled in the browser.

Also it allows the SERVER to process the textbox and decide which URL to open in the new window, as opposed to having the client do it.
