C# ASP.NET redirect to new browser window

From server side code I need to come up with some way to open a new window navigating to a different url. I have server side code that has to run first to get the url. I tried Response.Write(<script>window.open('http://testpage.aspx');</script>) and it works opening the new browser window, but the orignal page gets displayed wierd. The page is a web content form with a master page and it loses have of it's styles and content.

Is there a way to call a javascript function passing a url and have it open to a new window?

Hi,
you can use,

Page.RegisterStartupScript("myscript","<script>window.open('http://testpage.aspx');</script>");

in your code file.

Thanks,

Inject JS code like shown here:

I've tried the following two methods and it doesn't work. The Window never opens. What do I need to do to get the javascript to execute?
Also, this is coming from a web content form within a master page if that matters?
The code shown below is in the onclick event of the linkbutton.

// 1st attempt  

     StringBuilder sb = new StringBuilder();
            sb.Append("<script language='javascript'>");
            sb.Append("window.opwn('");
            sb.Append(NavigationManagement.System.ImagingViewer(imageId));
            sb.Append("');<");
            sb.Append("/script>");

            Type t = this.GetType();
            ClientScript.RegisterClientScriptBlock(t, "PopupScript", sb.ToString());

// 2nd attempt

            Page.RegisterStartupScript("myscript", "<script>window.open('" + NavigationManagement.System.ImagingViewer(imageId) + "');</script>");

Open in new window

In first attempt did you try:
ClientScript.RegisterStartUpScript(t,"PopupScript", popupScript);

Also are there any popup blockers or make sure your browser has javascript enabled.

You might want to download and add a JavaScript reference to the jQuery library (http://www.jquery.com) in your master page. Then adjust your script to be something like this:

string myScript = "<script type='text/javascript'>
$(document).ready(function()
{
window.open('" + NavigationManagement.System.ImagingViewer(imageId) + "');
});
</script>";

And then register it using RegisterStartupScript. This will ensure that the whole page/DOM is loaded before it executes your code. I had a developer with a similar problem yesterday and this fixed it.

I saw that I had a typo. I spelled open wrong. It works now using the RegisterClientScriptBlock approach, but it doesn't work inside an update panel. This logic is in a user control and this user contol is almost always within an update panel. I need it to work within an update panel.
Is this possible?

I changed my code as shown below, but it still doesn't work if the control is within an update panel.
The update panel has UpdateMode="Always".
And we aware of the popup blocker issue. This application is an internal application and the user's want it in another window, so we're trying to do that.

          StringBuilder sb = new StringBuilder();
                    sb.Append("<script language='javascript'>");
                    sb.Append("window.open('");
                    sb.Append(NavigationManagement.System.ImagingViewer(imageId));
                    sb.Append("');<");
                    sb.Append("/script>");                   

                    Type t = this.GetType();
                    //this.Page.ClientScript.RegisterClientScriptBlock(t, "PopupScript", sb.ToString());
                    this.Page.RegisterStartupScript("PopupScript", sb.ToString());

Open in new window

Your right. When I use the scriptmanager it works great. Thank you.
