Ive looked at the examples and modified it to suit my needs.  I only have one details table, the contents of this table are determined by the contents of 2 columns in the master table (neither of which is the datakey)  How can I obtain these values in the 

 

DetailTableDataBind event ?

How do I work with insert, delete and updates  for the master and detail tables ?

[mww]

I dont want all the values in the parent control.  Isnt there some way of getting the value of a specific column in the parent grid ?

for instance, the master table has 3 columns

ID , ArtistID &  Genre

I only need the values contained in the genre  and ArtistID columns to determine the contents of the detail table

Hello Mark,

Alternative approach is to access the cell contents directly.

protected void RadGrid1_DetailTableDataBind(object source, GridDetailTableDataBindEventArgs e)
{
    if(yourCondition)
    {
        GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;
        string artistID = dataItem["ArtistID"].Text;
    }
}

Let us know whether this helps.
