RadWindow from server

[Naupad]

I have this function on my aspx page.
function openWindow() {
          
            //get a reference to the window
            var oWnd = $find("<%= RadWindow2.ClientID %>");
            //set its NavigateUrl
            oWnd.setUrl("http://xyz.com/abc.zip");
            //add the name of the function to be executed when RadWindow is closed
            
            //show the window
            oWnd.show();
        }
I want to call this function in Button click event through RegisterStartupScript. It gets called but window doesn't open. Also I want to open a url which has a zip file for download. So as soon as user is prompted about Save dialog box, I want to close radwindow.

HELP!!!!!

Hello,

Try the following code to open RadWindow through RegisterStartupScript.
C#:

protected void Button1_Click(object sender, EventArgs e)
  {
    string openWindowScript = "<script language='javascript'>function f(){openWindow(); Sys.Application.remove_load(f) ;}; Sys.Application.add_load(f)  ;</script>";
    Page.ClientScript.RegisterStartupScript(this.GetType(), "radalert", openWindowScript);
  }

Thanks,
Princy.

Hi guys,

 I suggest to improve the sample code Princy provided in the following manner:

1) Use ScriptManager instead of ClientScript - this will handle more scenarios, e.g when an AJAX request was made.

2) Since your js function already has a name, it is not needed to wrap it the additional named f function.

With the above your code will look like the following:

js in aspx:

function openWindow() {
           Sys.Application.remove_load(openWindow);
             //get a reference to the window
             var oWnd = $find("<%= RadWindow2.ClientID %>");
             //set its NavigateUrl
             oWnd.setUrl("http://xyz.com/abc.zip");
             //add the name of the function to be executed when RadWindow is closed

             //show the window
             oWnd.show();
         }

code-behind:

protected void Button1_Click(object sender, EventArgs e)

  {


 ScriptManager.RegisterStartupScript(this, this.GetType(), "key", "Sys.Application.add_load(openWindow)" , true);

  }
