回答1:

Use

 <Binding Path="CmbColumnCollectionVergiTur">

  </Binding>

Or

  <Binding>
     <Binding.Path>CmbColumnCollectionVergiTur</Binding.Path>
  </Binding>

For multiBinding, the syntax should be

<MultiBinding Converter="{StaticResource myConverter}"
              >
  <Binding Path="CmbColumnCollectionVergiTur"/>
  <Binding Path="XYZProperty"/>
</MultiBinding>
