Add Row To GridView:

        int clientID = int.Parse(ddlClient.SelectedValue);
        int clientTypeID = int.Parse(ddlClientType.SelectedValue);
        ClientsAllCDO client = new ClientsBL().ClientsAllSelectByIDAndClientTypeID(clientID, clientTypeID);

You need to rebind the grid to the datasource:

//delete row from the database

GridView1.DataSource = SomeDataRetrievalMethod(); //retrieve the data from the database
GridView1.DataBind();
