Create own MessageBoxWindow with MessageBoxResult

[sidlercom80]

Hi, I have a problem with my own message box. I don't know exactly how to implement the "MessageBoxResult" to make it work properly. Maybe someone can help me.
This is what the message box looks like:



I hereby call the messagebox

var result = MessageBoxTest.Show(ChartControl, "Text");
await result;

Print("1=>" + result.Result);

I don't know how to implement this correctly in the. Show method so that I get the feedback when the "Ok" button was pressed. After the "Ok" button is pressed, for example, a next method with other functions should be executed, but only after the "Ok" button was pressed and not already when the window was opened.

    public static async Task<MessageBoxResult> Show(ChartControl chartControl, string text, MessageBoxButton buttons = MessageBoxButton.OK)
        {
            if (chartControl == null)
            {
                return MessageBoxResult.None;
            }

            MessageBoxWindowTest msgBox = null;
            System.Windows.Threading.DispatcherOperation msgResult = null;

            msgResult = chartControl.Dispatcher.InvokeAsync(() =>
            {
                msgBox = CreateMessageBox(chartControl, text, buttons);
                if (msgBox != null)
                {
                    msgBox.Show();
                    return msgBox.MsgBoxResult;
                }

                return MessageBoxResult.None;
            });

            await msgResult;

            return msgBox.MsgBoxResult;
        }

Hello sidlercom80,

The call and return of the message box would be synchronous. Meaning within the same block of the InvokeAsync action, trigger whatever actions you are going to trigger with the message box result.

Below is a link to a forum post with tips.

Hi ChelseaB, thank you for your reply. Unfortunately, with this variant, the chart is locked. Is there no alternative where a message box is displayed while the chart is not locked, waiting for the message "MessageBoxResult"? I would like to call only .Show() instead of .ShowDialog(), because with .Show() the chart is not locked. Unfortunately, the "MessageBoxResult" do not arrive there.

Hello sidlercom80,

The MessageBox is intended to be a modal window (meaning the chart or calling window is locked) and is intended to be code blocking until the OK or Cancel is clicked.

If you want a window that is not modal, you can open an actual window.

For example:

The result of the message box can be called directly under the show which is synchronous, but not outside of the invoke action.
