1. When executed I have a "Add Building" and "Click here to add tower" on the page.
2. When clicked on "Add Building" a editable gridview appears when I enter the text and say update.
3. When I click on "Click here to add tower" another button "Add Tower" is displayed on the
page.

5. When I click on "Add Tower" a editable gridview should be displayed but the editable gridview is not displayed ,it disappears.
6. Postback is happening ,so I am not getting where and how to handle the postback and even the viewstate

I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.

I have a dropdownlist("ddlTemplate") control and a gridview("gvPlanning") control with 1 BoundField column, 1 TemplateField column and remaining columns will be generated dynamically from database.In TemplateFiled Column i have 3 image buttons viz: Edit, update and cancel.Gridview will be populated based on the selecteditem of dropdownlist.
if i click on edit imagebutton, i need to add textboxes dynamically in all the columns of that row except first 2 column. And if i click on Update imagebutton i need to retrieve the textbox values.we can add template field column for textboxes also, but why i am sticking to this method is.. the number of columns changes depending on the selecteditem from the dropdownlist. Eg: If i select india from dropdownlist the number of columns in the gridview would be 4 and if i select UK from dropdownlist the number of columns would be 9 likewise.
<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) { }
I followed the article Nested GridView Example in ASP.Net using C# and VB.Net ..... It is a great article and very simple to follow. I easily modified it to suit my needs and added several more levels to the nested GridView.I am a VB.net Programmer and I have never used ASP.net or JQuery before.
The data I am using is very large and with the "OnRowDataBound" events, the Page is Pre loading all the data into the gridviews and the Plus/Minus images are just displaying/hiding the nested gridviews. The question is "How to make the nested gridviews populate dynamically?" I want to have the nested gridviews to databind when the plus image is clicked.
I added the below code to the Plus image click Function to execute the server-side "BindData" Function. however I don't know enough about ASP or Jquery to get the GridViewRowData to send to the server-side function.
$("[src*=plus]").live("click", function () { $.ajax({ type: "POST", url: "Main.aspx/BindData", data: '{}', contentType: "application/json; charset=utf-8", dataType: "json", error: function(err) { alert("err");}, success: function (msg) { // Do something interesting here. alert("ok") } }); $(this).closest("tr").after("<tr><td></td><td colspan = '999' width = '100%'>" + $(this).next().html() + "</td></tr>") $(this).attr("src", "images/minus.png"); }); Server Side "BindData"

In a page , when I click a button 'showDialog' I am loading the user control dynamically in a dialog. I am linking to the event in the user control as explained below. The parent page is not receiving this event.
