TextBlock text wrapping in GridViewColumn.CellTemplate not working
You are setting both DisplayMemberBinding and CellTemplate. Remove DisplayMemberBinding when you use CellTemplate. Also remove the Width for the TextBlock and it'll work
<ListView ...> <ListView.View> <GridView> <!-- ... --> <GridViewColumn Header="Description" Width="385"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock TextWrapping="Wrap" Text="{Binding Description}" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <!-- ... --> </GridView> </ListView.View></ListView>
