For this follow steps below
1. create a function BindGrid with input param tableName as string
2. In function BindGrid create a SqlDataAdapter with sql query "Select * from "+ tableName +""
3. Create a DataTable object and fill it with SqlDataAdapater
4. Pass it as DataSource to DataGrid
5. On SelectedIndexChange of DropDownList call function BindGrid and pass DropDownList.SelectedItem as param into it
