Scenario: I want to bind two properties to a column, So I created Text column and set DataMemberBinding property to binding these two properties,
<telerik:DataGridTextColumn HeaderText="Country">
<telerik:DataGridTextColumn.DataMemberBinding>
<MultiBinding Converter="{StaticResource MultiConverter}">
<Binding Path="Country" />
<Binding Path="City" />
</MultiBinding>
</telerik:DataGridTextColumn.
