c# - How to set DataContext in a Dialog Window to its parent's DataContext -

-

itemprop = "text">

I created a new window which I call after using the following code: 

  NieuwSimulatie NiewSimulatieWindow = New Investigation () {Master = this}; Bool? SimulatieAangemaakt = NiewSimulatieWindow.ShowDialog (); In the window "NieuwSimulatie" I want to do the same DataContext as in my MainWindow, or I try using RelativeSource I want to DataBind directly to Geuss DataContext, Ive tried Key:  
  & lt; Control: SplitButton X: Name = "ProjectNaam" DisplayMemberPath = "ProjectNaam" ItemsSource = "{Binding Static.Projecten, RelativeSource = {RelativeSource Mode = FindAncestor, AncestorType = Control: MetroWindow}}" />  
 
 But it does not work. 
 
 Please help me fix my databanking or set the datacentax of my window in the data contact behind Meteindo.

I have access to your datacentech, from which you create your own window How to:

NeivaSlimatity News Simulativindo = New New Evaluation () {Owner = this, Datacontex = Your Data Constance; }; Bool? SimulatieAangemaakt = NiewSimulatieWindow.ShowDialog ();

I want to change the color of the surface on the basis of another value (an ID) that is considered discrete (hence I In the simplified example given below, I have prepared a field with 3 different IDs: 0 / red on left 2 / blue 1 / green left But with the code below, I have some strange behavior on the border between red and blue (green Point) I think this is probably due to an interpolation! Code: import from import mlab np # np # my dataset -simplified-x, y, z = np.mgrid [-3: 3: 100] H, -3: 3: 100h, -3: 3: 100 h] value = NP. SQLT (x ** 2 + y ** 2 + z ** 2) # My color value: Volume is divided into 3 sub-versions taking colorvalues ​​with X = np.empty (values.shape) colorvalues [0:33,:,:] = 0 colorvalues ​​[33:66,:,:] = 2. Look [66:,:,:] = 1 src = mlab.pipeline.scalar_field (value) src.image_data.point_data.add_array (colorvalues.T.ravel ()) (1) .name = 'MyID' src.image_data. point_data.update src.image_data.point_data.get_array () # surface, contour = mlab.pipe...
