I have update button and return button on that page.If I click on update, It will update data in the database. New Page Index Load Employee List() 'FUNCTION FOR DATASET grd Employees.protected void Detail View1_Mode Changing(Object sender, Details View Mode Event Args e) protected void Detail View1_Item Updating(Object sender, Details View Update Event Args e) protected void Details View1_Item Updated(object sender, Details View Updated Event Args e) The Mode Changing event is raised when a Details View control attempts to change between edit, insert, and read-only mode, but before the Current Mode property is updated.At first I put all my code in text, then I got the message it was firing the Mode Changing event which wasn't handled so I put that method back as code to use.The problem remains, I still have to click twice before I go to Edit mode and Editing doesn't work.Vamos alterar o nome da página (Default.aspx) para Produtos : com o botão direito do rato em cima do nome do nome da página, na janela Solution Explorer, seleccionámos Rename, e alterámos o nome.Para mostrar os dados de uma tabela da base de dados num controlo Grid View vamos criar: um controlo data source, que efectua uma ligação à base de dados e executa um comando SQL (Select) e retorna os resultados, um controlo Grid View para carregar os dados do controlo data source e os mostrar.

I have a problem which can be solved two different ways.I have datagrid, View details button on the datagrid.If I click on the button, It will redirect to another page with all the details.Surgem as tabelas Carrinho, Categorias, Clientes e Produtos.Para visualizar o conteúdo de uma tabela com o botão direito do rato em cima do nome da tabela seleccionar Retrieve Data (pode ser necessário efectuar o Refresh).

I'm throwing an exception in the Item Inserting Event which I excpect to catch in the Item Inserted event using the Form View Inserted Event Args, however, the event does not flow from Item Inserting -Yes, for example, I validate and findout the length of the input exceeds the permisable value, then I throw a new Validation Exception(), ofcourse, I can simply handle it using condition checking but the actual problem is when I have an SQL Exception.
