Hi, 

Sorry if i was unclear in my previous post, but with the UnboundColumn, the DataContext is different from the DataContext of a TemplateColumn.  Instead, we offer more properties so users can have more options of what to bind to. 

So, you can't binding directly to your data without specifying a Path anymore. Instead, if you want to bind directly to your data, you need 

{Binding RowData} instead of {Binding}

and if you want to bind to a specific property in your data, you need:

{Binding RowData.PropertyName} instead of {Binding PropertyName}

Hope this helps clarify things.

I am trying to use a converter in Unbound column ,specifying the data context property and using converter.the data template is as follows

<DataTemplate x:Key="deleteButtonColumnTemplate">
   <Grid>
    <Button Tag="{Binding}" DataContext="{Binding}" Content="Delete" Click="deleteButton_Click" x:Name="deleteButton" IsEnabled="{Binding data_source , Converter=disableDeleteButton}"/>
   </Grid>

Note:data_source is a column in Grid and is also present in datasource object.

The column does not call the converter even after using DataContext.

I cannot access the unbound cel-button in events RowInitilize and ControlAttached.The cell's Control.Content property returns null  in these events

Hi, 

The UnboundColumn's DataContext is of type UnboundColumnDataContext which contains the following properties:

RowData, Value and ColumnKey.

So you definitely should still be able to user a converter as you have the data of the row in which the cell belongs to.

What happens in case of Unbound columns?

How can I access the Unboundcell and change the control(Button) inside it to enable/disable?

I cannot do this at design time..have to decide it dynamically.Cannot use converter as Unbound columns are not bound to the datasource.

Thanks

That worked - many thanks Darrell!
