Change/Refresh ValueTemplateKey

Hi Todd,

Changing the ValueTemplateKey of the PropertyEditor is not really supported, atleast not in regards of updating the UI immediately. You could accomplish that by customizing the PropertyGrid.ValueCellContainerStyle to change the DataTemplate used based on custom triggers. The DataTemplate can also use triggers to switch what it displays, but the style approach would probably be cleaner.

If you use triggers, then you'd need a property that could be used to set the "mode" (i.e. standard entry, setting a binding, etc). This could be an attached property set on the associated PropertyGridDataAccessorItem or a property the underlying data accessor (or even your own abstraction layer). So the context menu would set the "trigger" property, and the Style would switch up the DataTemplate based on the current value.

One thing to consider if you are trying to replicate the Visual Studio PropertyGrid. When using StaticResource, the "source" information is lost once you set the value. For example, if you were to set the TextBox.Text property to "{StaticResource MyString}", then TextBox would have the string value and you would not be able to determine were it came from. This is the reason I mention building your abstraction layer that can retain this information.

Do you publish the default PropertyGrid.ValueCellContainerStyle anywhere?  Note that I am using the trial version trying to prove a concept before we purchase.

Hi Todd,

If you are a WPF Studio customer you can download the default styles/templates at any time.  Or since you are evaluating right now, you can email our support address and we can send you the Style for that container.
