Join Multiple tables in DataGrid : Extending the DataGridTextBoxColumn

[Wedgetail]

Hi,

I am trying to join 3 tables in a single Datagrid control.

I have read George Shepherd's FAQ [5.56] and Microsofts KB Q319082 which gives a lot of details on how to do this.

However, the article only explains how to make the control for a 'Read Only' situation. I would like to extend it to enable editing of the fields from the parent tables.

Is there an article that explains how to do this.

Thanks
