  Hello.

  Microsoft.Xaml.Behaviors.Wpf 1.1.31
  
  ReactiveProperty 7.8.3

  DataGird:
  
  ComboBox GotFocus fires first by InvokeCommandAction

                      <DataGridTemplateColumn.CellEditingTemplate>
                          <DataTemplate>
                              <ComboBox Width="100" VerticalAlignment="Stretch">
                                  <bh:Interaction.Triggers>
                                      <bh:EventTrigger EventName="GotFocus">
                                          <bh:InvokeCommandAction Command="{Binding ComboBoxFocus, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}" PassEventArgsToCommand="True" />
                                      </bh:EventTrigger>
                                  </bh:Interaction.Triggers>
                                  <ComboBoxItem>Item A</ComboBoxItem>
                                  <ComboBoxItem>Item B</ComboBoxItem>
                                  <ComboBoxItem>Item C</ComboBoxItem>
                              </ComboBox>
                          </DataTemplate>
                      </DataGridTemplateColumn.CellEditingTemplate>
  

  c1:FlexGrid
  
  ComboBox GotFocus does not fire first by InvokeCommandAction.

  I need to use MVVM. So I’d like to use InvokeCommandAction.
  
  Will it be fixed?

  Hi Mikihiro,

  Thank you for sharing the sample.

  This behavior seems like a bug so I have escalated it to the devs and will get back to you when there is any update. (Internal Tracking Id - C1XAML-27333)

  Hi Mikihiro,

  As per the devs, you can set the EventTrigger’s SourceObject property to the ComboBox itself in order to overcome this behavior as follows:

  <bh:EventTrigger EventName="GotFocus" SourceObject="{Binding ElementName=comboBox}">
  

  Please refer to the same from the attached modified sample. (see CategoryOnGrid_Mod.zip)
