how to pop-up a new window from direct event handler

[captainst]

I think that it is another client-side vs server side issue, but I could't work out.

Almost all the EXT.net examples with direct event create the new window (or panel/viewport) in ASP.net Page_Load() function, some use the client-side event to display the window.

I tried to do things like this in a direct event handler (Button_Click is a direct event handler to a button click):

<script runat="server">
    protected void Button_Click(object sender, DirectEventArgs e)
    {
        Window win = new Window();
        win.Show(); 
    }
</script>

I noticed also that the examples put always a "placeholder" at the end, which is an asp.net server control. But even if I put that, nothing happens.

I have two questions:

1. Is it possible to launch a custom window from direct event handler?
2. If on this custom window, there are other custom components or buttons, in which way I can write the direct event handler for those buttons, or manipulate those components ?

Many thanks again!

I figured out that I should also call .Update() in order to show the newed window as follows.

But another problem raised: after the .Update(), I can't change the property of this window, even if I call "Update" again:

<script runat="server">
    protected void Button_Click(object sender, DirectEventArgs e)
    {
        Window win = new Window();
        win.Title = "title1";
        win.Show(); 
        win.Update();
        win.Title = "title2";
        win.Update(); // this does not change the title of the window.
    }
</script>

The following sample should help, see

https://examples1.ext.net/#/XRender/Basic/New_Window/

You just call .Render() once you're finished configuring the component.

Hope this helps.

Cool! Many thanks again Geoffrey! I did not notice that example at the bottom.

It is a bit difficult to grasp the things without a step-by-step guidance. It would be a great boost for beginners along with the rising popularity of ASP.net.
