ToolWindow IsFloating MVVM Binding - Docking/MDI for WPF Forum

Posted 4 years ago by JP Garza

Version: 19.1.0685

Hello,

How would I bind to my ToolWindow's IsFloating attribute?

I currently have this code:

<docking:DockSite x:Name="outerDockSite">
<docking:ToolWindowContainer x:Name="outerToolWindowContainer">
<docking:ToolWindow x:Name="outerToolWindow" IsFloating={binding IsToolWindowFloating, mode=OneWayToSource}>
<Grid/>

but IsToolWindowFloating is not getting updated even though I am seeing the ToolWindow IsFloating is changing in the visual tree properties.

Note: out of all the binding in my ViewModel this is the only one not working. I don't think the problem is on the .cs implementation of IsToolWindowFloating.

Thanks and Best!

Hi JP,

It should be working ok. I just did a successful test.

If you look at our MvvmToolWindows QuickStart, it is showing a ListView that binds to various properties like IsFloating of the view-model to show their current state. That seems to be updating ok when I float a tool window there. That would mean the actual ToolWindow is pushing its IsFloating state back to the view-model ok, and then the ListView is showing the updated view-model's IsFloating value.

For some reason when you dock the ToolWindow it does not notify the viewmodel that IsFloating has changed. Since that did not work for me I moved to a solution of binding to the controler itself:

{Binding ElementName=myToolWindow, Path=IsFloating}

Thank you.
