Accessing current record using OnDraw ''rowIndex''

[Russell Coombes]

Hi,
I am using a class that inherits from GridGenericControlCellRenderer. Within the OnDraw method, I am given the 'rowIndex'. When I have only one row in my DataTable datasource, I would expect the rowIndex to be 0 for the first row, but instead it is 1. I assume that it is because the hidden ColumnHeader has rowIndex 0.

So how do I use this rowIndex to obtain the current record? And how can I get the DataRow that the current record will be bound to?

Please note, that I am NOT prepared to accept an answer that includes accessing a row using 'rowIndex - 1'!

Thanks,
Russell

If you are using a GridDataBoundGrid as your bound grid, then you can use:

int position = gridDataBoundGrid.Binder.RowIndexToPosition(rowIndex);

I am using the GridGroupingControl, so I'm afraid this won't help me.

Do you have the equivalent code that will work with the GridGroupingControl?

Thanks,
Russell

In a GridGroupingControl, you can access the underlying record through the style object.

            GridTableCellStyleInfo tableStyle = style as GridTableCellStyleInfo;
            Record r = tableStyle.TableCellIdentity.DisplayElement.GetRecord();
            if (r != null)
            {
                //use code like this to access the field values
                object o = r.GetValue("SomeFieldName");
            }
