Filter Datagrid Data Via DropDown List Selection
Here, in this example, we have two SqlDataSource Controls and they both tied to Authors table of the Pubs database. The first data source control (Marked as 1) supplies data for the grid control (Marked as 3). The second data source control (Marked as 2) supplies the data to the combo box control (Marked as 4). When a user selects a state in the combo box, the DataGrid will update the authors listed in the DataGrid.
