[Solved] RadWindow.Confirm Inside a RadWindows.Prompt

[Ernie S]

I have a rad window that popups up asking the user for a Save As name.  In the handler that is called after it closes it checks to see if the name alredy exists.  If it does, I want to get overwrite confirmation from the user in another RadWindow.  This is where I cannot figure out how to do it since the Confirm window, like the Prompt, reacts to the user input through the use of the delegate.

I have it working with the plain Windows MessageBox (Line 20) but how would I do it with the RadWindow?

01.private void SaveAs()
02.{
03.    RadWindow.Prompt(
04.        "Please enter the name of the new view"
05.        , (sender, args) =>
06.            {
07.                if (args.DialogResult != true)
08.                    return;
09.
10.                //See if it already exists
11.                var id = -1;
12.                var foundviews = SerializedViews
13.                    .Items
14.                    .Cast<SerializedView>()
15.                    .Where(sv => sv.Name == args.PromptResult)
16.                    .ToList();
17.
18.                if(foundviews.Any())
19.                {
20.                    var result = MessageBox.Show("Already exists, overwrite?", "Confirm:", MessageBoxButton.OKCancel);
21.                    if (result == MessageBoxResult.Cancel)
22.                        return;
23.
24.                    id = foundviews.First().Id;
25.                }
26.
27.                .......
28.
29.                SaveView(view);
30.            });
31.}

Hi Ernie,

In Silverlight RadWindow.Confirm and RadWindow.Prompt are not blocking operations - the code continues its execution even after such windows are opened. MessageBox itself is using some internal framework logic to block all operations, that's why it is possible to use it in your scenario. In case you decide to use RadWindow.Prompt and inside it RadWindow.Confirm, the prompt window will be closed even if your confirm window is still opened. In order to achieve the desired result I suggest you to use your current code with MessageBox or raise a flag (internal property of your class) in your RadWindow.Prompt closed handler in order to know that confirm window is opened. After that instead of executing your other logic when Prompt window is closed, you can execute it in Confirm window's closed handler.

Hope this helps.

Thanks Rosen, thats what I though.  Is there anything equivalent prompt in your controls that provides blocking?  I wanted to use the RadWindow because we do a lot of style injection at runtime so it is easier to use it to maintain a consistent look.

Thanks

Hello Ernie,

I'm afraid that our dialogs doesn't support that blocking behavior. However you can try the approach Rosen already suggested in our previous post.

If you have any other questions or concerns - let us know.
