How to make the button_Click event opens the page in a pop-up window in ASP.NET?

Question

The question is simple but I can't find a simple answer to it! .. btw I'll need to pass a QueryString to the page to be open.

Any ideas ?

Answer 1

You can actually link a javascript code into .NET with C#, below is an example, you could replace with your info, and push the parameters.

   Response.Write("<script type='text/javascript'>window.open('Page.aspx?ID=" + YourTextField.Text.ToString() + "','_blank');</script>");

You can append on the end of it ?Field=your value passing&nextField=another value.

Answer 2

Is the answer to do this in javascript. As you make the underlying page in asp.net, provide it with the javascript to catch the buttons onclick event and call window.open(URL)

Answer 3

It depends on what you're trying to do but the simplest is to use the OnClientClick property of the Button. Take a look at http://msdn.microsoft.com/en-us/library/7ytf5t7k.aspx, in particular the details bout this property a little bit down.

Basically you'd do something like

<asp:Button ID="Button1" Runat="server" 
        OnClientClick="ShowPopup();" 
        Text="Test Client Click" />

With the JS to do your popup

<script type="text/javascript">
    function ShowPopup() {
        window.open('ThankYou.aspx');
    }
</script>

You can also do both an OnClientClick and an OnClick if you need as well.

<asp:Button ID="Button1" Runat="server" 
      OnClick="Button1_Click" 
        OnClientClick="ShowPopup();" 
        Text="Test Client Click" />

Code behind

    protected void Button1_Click(Object sender, EventArgs e)
    {
        Label1.Text = "Server click handler called.";
    }
