Can I map Grid cell to row in DataSource?

Looking for a way to get to the exact row in the DataTable, give the row index in the Grid. I am using the GridDataBoundGrid and am binding to a hierarchical DataSet. Is there a way to do this? Tx, curt

Have you tried this.gridDataBoundGrid1.Binder.RowIndexToListManagerPosition to see if that will give you the value you want?

Hey Curt! I'm working on the same issue. According to another post, Binder.RowIndexToListManagerPosition will work until the datagrid ordering changes (through a sort, on new rows added), then the index into Rows doesn't match up anymore. Instead, you should index through Table["table"].DefaultView.Item[Binder.RowIndexToListManagerPosition] I can't test this though - for some reason, the compiler is complaining that Item is not a property of a DataView. The docs clearly state that it is (unless I'm missing something stupid). I'm going to install .net framwork sp2 and see if that fixes it.

Now I see my mistake. You access it like this: ds.Tables["table"].DefaultView[Binder.RowIndexToListManagerPosition] Compiles but still not working for me. ANdy

Does this not work? int nRowIndex = grid.Binder.CurrentRowIndex; int nListIndex = grid.Binder.RowIndexToListManagerPosition(nRowIndex); DataRowView drv = ds.YourTable.DefaultView[nListIndex];

It was not giving me the correct row in the datatable when the datagrid was sorted. I studied a working example from another post and found one difference with my code - in my code, I set datagrid.datasource equal to the dataset, and datagrid.datamember = "table name". In the working example, datagrid.datasource is set to the datatable (the object). I made that change in my code and now it works. Looks like a bug. I'm using grid ver 1.5.2. Andy
