Based on the error, it looks like your PurchaseOrderItemEntity has gained a reference to your AddEditPOItemViewModel instance somehow. You'll need to dig into its properties to find out where that reference is, and mark the reference as "not serialized".

I have a DataGrid with a DataGridTemplateColumn with a combobox inside it. The combobox is populated by enums using an ObjectDataProvider. The ComboBox DataTemplate renders the enum items hyperlinks.
I want to disable hyperlinks that should not be clickable based on some value on the entity. I'm not sure how to go about this.
I considered the CodeProject one but settled on the smithhtmleditor. Seems to be working Ok, a little quirky with fonts but other than that fairly easy to use. All I need is some basic editing for keeping notes in the app I'm working on.
I'm working on a WPF app that we now want to have a 'Test Mode'.
Right now, I have an 'IsTestMode' property in the app.config. If I set it to True, then the login window's border is red, and there's a red TEST MODE banner across the top of the main window. The Test Mode copy is installed in a different location then the production copy.
In the code behind of the Main Window I have:
Uri iconUri = null;
iconUri = new Uri("my_test.ico", UriKind.Relative);
iconUri = new Uri("my.ico", UriKind.Relative);
this.Icon = BitmapFrame.Create(iconUri);
This changes the Taskbar Icon, not the desktop icon
This all works fine.
Now I want to add an installer project, but I'm stuck on how to make the Test Mode changes during installation. I'd like to do the following during installation and not let the user change them:
Set the installation location
Set the IsTestMode setting
Change the desktop icon.
Can anyone shed some light on how to do this?
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
As it is now, the textbox will change it width but not it's height, due to it being set to 225 in the grid definition. However, I am unsure how to set the grid so that it will take up the space but leave the bottom controls visible. Basically I want it to be as it is now but able to resize.
The purpose of this code is open image file in a page and display it in another page.
I had tried set ViewModel by using Singleton Pattern, but it didn't work....
If I integrate to one View, it can display the image correctly. But I need to separate the views.
I have no idea what's wrong in this MVVM code....and how to fix it?
Please point me how can I do or let me know what keyword I can search the toturial/sample.
Thank you all.
The OpenFile button is on DisplayControlView and display on DisplayView.
The View Schema is as below: MainWindow.xaml (window)
