could you give us an example of what you're trying to achieve? because binding different columns to different datasources doesn't make much sense to me. Might just be me though ;) Please clarify.
public object BufferOverFlow { __get { return BufferOverFlow; } __set { BufferOverFlow = value; } } -

public object BufferOverFlow { __get { return BufferOverFlow; } __set { BufferOverFlow = value; } }ya sure. well here is my case. i have a database, which has several columns. I need to modify the contents of a single column. Looking at a different side, binding a single column to a separate data source doesnt make sense to me either. what I really want is to modify the contents of a cell of a column of a datagrid. Can i do it using a datatable or a dataset, coz it is much faster, than accessing a datagrid as Datagrid1.Rows[i].Cells[j]. m trying to modify a cell. how to do it, if i bind a datagrid to a datatable.

You can edit individual cells in DataTables in the same way as you edit cells in a DataGridView. You can (or have to) use DataTable.Rows[i].Cells[j]...
public object BufferOverFlow { __get { return BufferOverFlow; } __set { BufferOverFlow = value; } }well ok. as u said in the previous replies, when i try to bind a datagrid to a data table and try to access the cell or the row count of the data table, it says object reference not set. it comes null. here is how i try to bind a datagrid to a datatable. DataTable dt1=new DataTable("dt1"); dt1 = (DataTable)LoggerDatagrid.DataSource; please tell me, if I am making a mistake anywhere. thanks in advance.

You're doing it the wrong way around. It should be :
LoggerDatagrid.DataSource = dt1;now your datagrid should be populated, and then you can start looking for cells to edit.
Visual Studio can't evaluate this, can you?
public object moo { __get { return moo; } __set { moo = value; } }
