How to Reposition a WPF Modal Window at the center of the Screen?



In my earlier post “How to Reposition a Silverlight Child Window?”, I demonstrated you how to reposition a Silverlight Child Window into the screen. I tried the same with the WPF Modal Window too. But was not able to make it.

 

Later Thomas Claudiush gave me a cool sample where he did it very easily. In this post, I am going to share that code for you so that, if in near future you need the same behavior, you don’t have to research for it again.

Sometime we need to reset the position of the Silverlight Child Window at the center of the screen. This generally require when you have a static instance of the ChildWindow and you want to use the same instance to show various messages in the screen.

But think when your user reposition that ChildWindow to a different location in the screen, closes and reopens it, what will happen?

I have seen people writing Code Behind a lot while they are working in the MVVM framework. A huge lines of code in their xaml.cs file actually creates problem to the designers to change anything present in the XAML. Why is this so?

In this article, I will show you how to fire Triggers to call some methods present in your ViewModel, instead of writing in the code behind file. Read more to learn about it.
