C# WPF UI Tutorials: 21 - Custom Dialog System Message Box Popup

Part of a series of tutorials on creating WPF applications in C#

In this we create a custom reusable dialog window system and make a basic message box popup styled in the same style as our application.

We also add a nice dimmed background to focus the users attention on the dialog.

Thank you so much for these videos - very useful indeed! It is difficult to find learning resources for WPF that follow best practices and are up to date, really appreciate you sharing this with the world.

[BondTricks]

My God !!! You are an expert in doing this .. Great ... and Thanks for helping ... I will always be in debt of you. Thank You..

Nice work as always. Espacially with the background effect when the message is showing or the window unfocused.

I'd love to see some videos about asynchronous and synchronous programming in C#.
Btw. great job as always!

Hello again, within the MessageBox I miss a little bit a list of buttons instead of just one. I can only imagine a Dialog Box : Do you want to continue? Yes / No. Rarely a 3rd button is needed ( or more ) but as example: Share this message: Facebook / Twitter / Google+. Another kind of control could be input box to ( for example ) set a user status visible to others. Enjoy the bank holiday weekend !

Really enjoying this series - going through them for the second time and now really understanding why you do things as you do (and at my age that is a miracle!). Looking forward to learning how to bind to databases and then I will be ready to start on an app I have had in mind for some years.
Really stupid question: When you are entering comments in the code-behind you have a nice multi-line format which you seem to be entering with a keyboard short cut ... how??

thank you for this great tutorial! realy thank you

[muhanad]

awesome clear video. If I am not mistaken you are following MVVM here right? Do you use any framework fro it? Also, I want to mention that DialogWindows are awaited by default, so I don't think to await in the ViewModel ICommand unless if I'm missing something here! Thank you again

Question how did you do fasetto word and fasetto core? Is there a specific video?

[JJayToKlamca]

21st episode and I still don't understand 3/4 of the code. I guess I will have to go all the way from the begining of the series and analize everything more carefully. Well, hot-headedly writing code after you just to see things work amazingly wasn't the best idea after all ;(
edit. At least I have holidays right now, so I have plenty of time to do so :)

How to make items in sidemenu list clickable(selectable) and how to check which one is selected?

[tomas]

Why we have to do this:

*// Create a task to await the dialog closing
var tcs = new TaskCompletionSource<bool>();

Task.Run(() =>
{
// Run on UI thread
=>
{
try
{
// Show dialog
new DialogWindow().ShowDialog();
}
finally
{
// Let caller know we finished
tcs.TrySetResult(true);
}
});
});

return tcs.Task;*

and not simply write *new DialogWindow().ShowDialog();* ??
