Hi, You have the two drop downs and already you binded with them. Create the ListBox in ASP.Net and now you want to bind the third table based on the two dropdown selection. Create the stored procedure CREATE PROCEDURE Proc_FillListBox @ddl1ID INT, @ddl2ID INT AS BEGIN SET NOCOUNT ON SELECT * FROM thirdTable WHERE col1=@ddl1ID AND col2=@ddl2ID END Execute it in your sql server query window. Write the code in the code file: SqlConnection sqlConnection = new SqlConnection(); sqlConnection.ConnectionString = @"Data Source=SQLEXPRESS;Initial Catalog=Master;Integrated Security=true;"; sqlConnection.Open(); SqlCommand sqlCommand = new SqlCommand(); sqlCommand.CommandType = CommandType.StoredProcedure; sqlCommand.Connection = sqlConnection; sqlCommand.CommandText = "Proc_FillListBox"; sqlCommand.Parameters.Add("@ddl1ID", SqlDbType.Int).Value = Convert.ToInt32(ddl1.SelectedItem.Value.ToString()); sqlCommand.Parameters.Add("@ddl2ID", SqlDbType.Int).Value = Convert.ToInt32(ddl2.SelectedItem.Value.ToString()); SqlDataAdapter sqldataAdapter = new SqlDataAdapter(sqlCommand); DataSet dataSet = new DataSet(); sqldataAdapter.Fill(dataSet); //Fill the ListBox lstBackupfiles.DataSource = dataSet.Tables[0]; lstBackupfiles.DataBind();
