When I click the Browse button in the UserControl the DependencyProperty "FilePath" is correctly set and the textbox gets the path string but the model doesn't seem to work. If I type something manually in the UserControl instead than filling it trough the Browse button it doesn't work anyway. As suggested from AnatoliyNikolaev thanks to his explanation on UpdareSourceTrigger and Karuppasamy in the User Control it can be done like this use the UpdateSourceTrigger explicitly because it's a textbox:.

I have tried the same and have set the UpdateSourceTrigger to PropertyChanged while binding the TextBox in the UserControl's XAML code. Below is my code. Try for your dependency property set UpdateSourceTrigger to PropertyChanged:. The default is Defaultwhich returns the default UpdateSourceTrigger value of the target dependency property. However, the default value for most dependency property is not updating the bound property properties is PropertyChangedwhile the Text property has a default value of LostFocus.

I've created this simple reusable control to browse files. Then I did a model and implemented the OnPropertyChanged and used the control in MainWindow. If I type something manually in the UserControl instead than filling it trough the Browse button it doesn't work anyway This is the code for the UserControl, the property is set correctly within the control: Register "FilePath", typeof stringtypeof FileBrowserTextBoxnew FrameworkPropertyMetadata string.

As suggested from AnatoliyNikolaev thanks to his explanation on UpdareSourceTrigger and Karuppasamy in the User Control it can be done like this use the UpdateSourceTrigger explicitly because it's a textbox: Hope I understood your problem, I have tried the same and have set the UpdateSourceTrigger to PropertyChanged while binding the TextBox in the UserControl's XAML code.

Why are you writing the same thing, I've already written about this in my answer? AnatoliyNikolaev I have mentioned to add UpdateSourceTrigger to the UserControl itself instead adding it while using as you said. And I think adding the UpdateSourceTrigger while using it, doesn't work. If i use the UpdateSourceTrigger in the UserControl itself it's not working, in the MainWindow yes. What's the correct binding expression in the MainWindow and in the the UserControl to make it work? Try for your dependency property set UpdateSourceTrigger to PropertyChanged: If it works, why do not my answer accepted?

I used the second answer in the end, adding the code in the UserControl, was cleaner and there is little typing in the MainWindow. I posted the way I fixed it in the question itself. I used theUpdateSourceTrigger in the control so I thought to accept that reply. Sign up or log in StackExchange. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name.
