"Bind" DataGrid to ComboBox - bound in wrong direction

Hello to everybody!

I have a DataGrid - populated by DataSource property - set to a TableBindingSource. (When the form loads all records in the table are displayed)
I have a ComboBox - populated by DataSource property - set to a BindingSource which has only two columns (ID, Title)

I want to update the DataGrid according to the item selected in the Combobox. The desired behaviour is that the DataGrid shows only those records where seller_id(in the TableBindingSource of the DataGrid) is equal to the selected Combobox row id.

I set up the binding of the ComboBox as I thought it would be correct. But now, when I select a record in the DataGrid my ComboBox gets updated to the right Seller title, while selecting anything in the ComboBox has no effect on the DataGrid.

I will appreciate any comments.

OK, I have again not understood the concepts behind this, I found a thread(http://www.vbforums.com/showthread.p...obox-selection which seems to handle my problem, the key point is to use Filter property to the BindingSource. I'll try that now
