Glen,
You should specify the DataSource for your child grid like this:
dgmain.DataSource = m_oTest.OleDataSet.Relations("sCombine").ParentTable
dgmain.DataMember = "sCombine"~~Bonnie
>I make a "datarelation" into my two tables. It is working! But my problem was, I want to have a navigation toolbars(movfirst, movnext,.....) wherein the "parenttable" was bind to the textbox and the "childtable" was bind to datagrid. How can I do that..
