How to dynamically set InputValue1 in M3 MI ComboBox using binding value from previous combobox?

I've tried many combination in the event as target key but nothing worked.

 

comboboxname.InputValue1

MIComboBox.InputValue1.Text

MIComboBox.InputValue1.Value

InputValue1.Text

 

Nothing worked.

Binding two MiCombox directly is not yet enabled in H5 but will be supported in a future patch. For now, I suggest to bind a "hidden" textbox in the first micombobox then bind that textbox to the second combobox as dynamic InputValue1. See sample below:

<m3:MIComboBox Name="comboTest1" InputName1="LANC" InputValue1="ES" SortField="LANC" SelectedValuePath="[LANC]" SelectedValue="{Binding ElementName=textboxTest, Path=Text}" DisplayMemberPath="[LANC]" Grid.Row="1" Grid.Column="0">
 <m3:MIComboBox.DataSource>
  <m3:MIDataSource Program="MNS105MI" Transaction="LstLng" IsCacheable="True" />
 </m3:MIComboBox.DataSource>
 <m3:MIComboBox.Events>
  <mashup:Events>
   <mashup:Event TargetName="comboTest2" SourceEventName="CurrentItemChanged" TargetEventName="Refresh" />
  </mashup:Events>
 </m3:MIComboBox.Events>
</m3:MIComboBox>
<TextBox Name="textboxTest" HorizontalAlignment="Left" VerticalAlignment="Center" Width="300" IsReadOnly="True" Visibility="Hidden" />
<m3:MIComboBox Name="comboTest2" InputValue1="{Binding ElementName=textboxTest, Path=Text}" InputName1="LANC" SortField="LANC" SelectedValuePath="[LANC]" DisplayMemberPath="[TX40]" Grid.Row="2" Grid.Column="0">
 <m3:MIComboBox.DataSource>
  <m3:MIDataSource Program="MNS105MI" Transaction="LstLng" IsCacheable="True" />
 </m3:MIComboBox.DataSource>
</m3:MIComboBox>

Hope that helps,
