UI ComboBox in DatagridColumn

[BollerwagenIng]

Hello,

I crate a DataGrid and I want to insert for every row in the third column a ComboBox. I am so far til now:

def getUIContent():
   my_toolProperty = sdk.ToolPropertyContainer()   

   # Define UI
   my_toolProperty.ToolPropertyContent = getCustomToolPropertyContent()
   
   # Update Grid
   UpdateDataGridData()
   
   return my_toolProperty
def getCustomToolPropertyContent():

   # Create a Grid
   my_Grid = WPFControls.Grid()

   # Add 1 Row and One Column
   my_Grid.RowDefinitions.Add(WPFControls.RowDefinition())
   my_Grid.ColumnDefinitions.Add(WPFControls.ColumnDefinition())
  
   # Create a DataGrid
   global myDataGrid
   myDataGrid = WPFControls.DataGrid()
   
   # global myComboBox
   myComboBox = WPFControls.DataGridComboBoxCollumn()

   
   # Add the DataGrid to the Grid 
   my_Grid.Children.Add(myDataGrid)

   # Return the Grid   
   return my_Grid

# def UpdateData (it's only the Path of api / not important)

@apex_sdk.errorhandler
def UpdateDataGridView():

   # Retrieve grid results
   grid = sdk.getScriptFunctionReturnData()

   # Create table
   data_table = WPFData.DataTable("Contents")
   data_table.Columns.Add("Prename")
   data_table.Columns.Add("Last Name")
   
   # Add data to the table for each name
   parts = grid['Name']
   for name in names:      
      data_table.Rows.Add(part['prename'], part['lastname'])
   
   # Set the IetmsSource for the data grid to the DataTable 
   myDataGrid.ItemsSource = data_table.DefaultView
   # myDataGrid.ItemsSource = myComboBox     ??? 
   
   # Position the DataGrid in the first row, column of the Grid
   WPFControls.Grid.SetRow(myDataGrid, 0)
   WPFControls.Grid.SetColumn(myDataGrid, 0)
