I'm here again to share a problem that I'm fighting against for days. I'm developing an eCommerce Cart.
Within it, I have a repeater, inside of ITEMTEMPLATE I put one TextBox for product quantities and one Button, for update the quantity inserted on that textbox.
When the customer clicks over the Button, it fires a function that gets the content of the TextBox and do an update on my Database.
It works perfetly when it is done with the mouse click. But I need to fires the update function WHITHOUT the manually click event. When the customer just put the mouse out of the TextBox (onblur event), I want to fires that function.
<asp:FormView DefaultMode="Edit" ID="FormView1" runat="server" onitemupdating="FormView1_ItemUpdating"> <EditItemTemplate> <asp:TextBox ID="txtPrimerNombreNatural" runat="server" SkinID="texto" MaxLength="30" Text='<%#Bind("PrimerNombre") %>'></asp:TextBox> <asp:TextBox ID="txtSegundoNombreNatural" runat="server" SkinID="texto" MaxLength="30" Text='<%#Bind("SegundoNombre") %>'></asp:TextBox> </EditItemTemplate> </asp:FormView> <asp:Button ID="Actualizar" runat="server" Text="Button" CommandName="Update" /> This formview is bound in this way: protected void Page_Load(object sender, EventArgs e) { Persona _persona = new Persona(); _persona.ObternerPersonaByUserIdApp(1); List<SILPA.AccesoDatos.Generico.PersonaIdentity> persona = new List<SILPA.AccesoDatos.Generico.PersonaIdentity>(); persona.Add(_persona.Identity); FormView1.DataSource = persona; FormView1.DataBind(); }
When the page is shown, the textbox are filled correctly, this textbox are filled with the "primernombre" and "segundonombre" properties from the persona class. After this, If I change the textbox, and after click the update button, I need to update the persona class with the changes from the textboxes, then I call a ActualizarPersona method for updating the database. How can I do for update the persona class when I change the textboxes and click the update button? I try this method protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e) { }
public int deleteProduct(int ProductID, int rowid) { // Create the Database object, using the default database service. The // default database service is determined through configuration. Database db = DatabaseFactory.CreateDatabase(); DataSet productsDataSet = new DataSet();
[Code] ....
The above code am using but throwing below error how to resolve
"Update requires a valid UpdateCommand when passed DataRow collection with modified rows."
In my ASP.Net application I have several pages that provide a list of items from the database. Currently we are using an UpdatePanel to refresh the whole list on a certain interval so that changes from other users will be propagated the screen. Obviously this isn't very efficient and we don't think it will scale well.What are some other methods for accomplishing this. Is there a specific pattern for addressing this issue?
My gridview works fine without the following code, but as soon as i add this, there is a probleme, when i click on delete or update button, i see no change, it's all the same.

asp.net Code: 'If e.Row.RowType = DataControlRowType.DataRow Then Dim A As Integer A = e.Row.Cells(13).Text.Length If A > 6 Then e.Row.Cells(13).Text = e.Row.Cells(13).Text.Substring(0, 6) End If End If End Sub
