PopUp with RadWindows

[archimede]

I want to create a popup on my web page. I want to use the RadWindow to accomplish this.

I'd like to invoke the control by server code instead of with window.radopen. Is it possible?

I want also to pass parameters to and from popup. How can I do this?

Has someone a simple example of this?

Thank you.

Hi,

It is possible to open RadWindow from code behind, but make sure that VisibleOnPageLoad property of window is set to True. Here is teh example.

C#:

    protected void Button1_Click(object sender, EventArgs e)
    {
        RadWindow window1 = new RadWindow();
        window1.VisibleOnPageLoad = true;
        this.form1.Controls.Add(window1);
    }

You can use the window URL to pass parameters that are read on the server-side to configure the controls inside the window. Checkout the following link to know more about this.

It works, thank you!

Only one thing on parameter-passing. I have this situation:

    - A main page with a formview or some controls 
    - Next to some controls (dropdownlist) I use a button that allow to insert some list new values (with a radwindow "popup")
    - When user insert the value and closes the popup I want the newly inserted value selected in main-form dropdownlist
    - I want also the data inserted by user before opening the popup, remain stored also after the popup closing. If I have 5 dropdownlist controls  and the user selects the values of each of the first 4 and then clicks on the 5th's button to insert a value, when the popup closes, the first 4 selected values must reamain unchanged, and the newly 5th value inserted by popup must be selected
    - If possible I'd like not to use Javascript because my web application has to work without it (Stanca accessiblity law)

I suppose to use the viewstate on main page to store controls data, maybe I can use also URL to pass parameters to/from popup. In this way I have to recall main page load to do reload parameters.

Are there different way to accomplish this without javascript?

Hi archimede,

If you don't want to use JavaScript, you could also try using session, or as an alternative - to use RadWindow as a controls container. In such case the content of the window is on the same page and you can access it directly from codebehind.
