How can i dynamically add textboxes and dropdown lists on a button click. I'll be showing 4 text boxes and 1 dropdown list initially with a link button ADD MORE, Then after clicking ADD MORE button i need to generate same 4 text boxes and dropdownlist exactly in the below row as in EXCEL sheet.
I'm having a SQL table with 4 textboxes and a drpdown list values as columns and i need to insert them into the database. i previously worked on the same requirement where i've collected multiple values frm a listbox control and looped all the selected items and comma seperated them and inserted them into table(here the case is different, there is only one row so it became simple and straight forward during insertion). Now i need to loop throguh all the 4 textbxes which user enters and need to insert those 4 textboxes values into DB under same columns.

View 1 RepliesI have an ASP:Button inside a Repeater control. The repeater is databound in code-behind. The Button text is populated with the data field value. When I click on one of the buttons, I want the text value to update a variable whos value is used to re-query the sql tables and redisplay the page. What I have so far does not update the value when one of the buttons is clicked.
Code:
asp code for the repeater:
<asp:Repeater ID="rptYears" runat="server" OnItemCommand="yr_ItemCommand">
<ItemTemplate>
<asp:Button ID="btnYear" runat="server" CssClass="yrBtn" Text='<%# Eval("YR") %>' />

I have a WebUserControl with a Button and some other controls (placeholder for images, labels). On a certain page, a number of these WebUserControls are created (using Me.LoadControl) and added to a PlaceHolder on the page.When the user clicks the button on either of these usercontrols, I want a method on the page to be called. I have been doing this by handling the Button Click event on the usercontrol, and then letting the usercontrol raise another event. I use AddHandler after creating the usercontrol to add an eventhandler method to this custom event. Sounds confusing? Here's a simple example.
The WebUserControl:
asp Code:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="TestControl.ascx.vb" Inherits="CSLimitedEdition.Controls.TestControl" %><asp:Button runat="server" ID="btn" Text="Button" />
vb.net Code:
Namespace Controls Public Class TestControl Inherits System.Web.UI.UserControl Public Event ButtonClicked As EventHandler ' Just some property to test with Public Property Number As Integer Protected Sub btn_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btn.Click ' When the button is clicked, raise a ButtonClicked event to handle on the Page RaiseEvent ButtonClicked(Me, e) End Sub End ClassEnd Namespace
The Page to place a number of these controls on:
asp Code:
<%@ Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site.Master" CodeBehind="TestPage.aspx.vb" Inherits="CSLimitedEdition.Pages.TestPage" %><asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server"></asp:Content><asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <p> <asp:Label runat="server" ID="lbl" /> </p> <p> <asp:PlaceHolder runat="server" ID="placeHolder" /> </p> </asp:Content>
vb.net Code:
Imports CSLimitedEdition.Controls Namespace Pages Public Class TestPage Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Me.IsPostBack Then Me.AddControls() End If End Sub Private Sub AddControls() For i As Integer = 1 To 5 ' Create the control Dim c As TestControl = DirectCast(Me.LoadControl("~/Controls/TestControl.ascx"), TestControl) ' Set some property for testing and add event handler c.Number = i AddHandler c.ButtonClicked, AddressOf TestControl_ButtonClicked ' Add it to the place holder placeHolder.Controls.Add(c) Next End Sub Private Sub TestControl_ButtonClicked(ByVal sender As Object, ByVal e As EventArgs) ' When a button on a usercontrol is clicked, set the label text to the 'Number' property of that control Dim c As TestControl = DirectCast(sender, TestControl) lbl.Text = c.Number.ToString() End Sub End ClassEnd Namespace
The idea is this:Button is clicked on the TestControl: TestControl.ButtonClicked event is raised. On the TestPage, the bestControl_ButtonClicked method is called The Number property of the calling TestControl is assigned to a label so I can see it. However, it seems that the TestControl_ButtonClicked method is never called. Via debugging I can confirm that the Button Click event, on the TestControl usercontrol, is fired, so that the TestControl.btn_Click method is called. The TestControl.ButtonClicked event is raised.After creating a TestControl, the AddHandler statement is executed. After clicking a button on the page however, nothing happens. The page just posts back, all the buttons are gone (ok, I'm not loading them again in case of a postback), but the label does not get the text.In fact, the ButtonClick handler method (TestPage.TestControl_ButtonClicked) method is never called! What could be causing this? I am sure that I have been using this method a few weeks ago, in this very project, yet suddenly it has stopped working. I thought it might be a one-time thing but with these new TestControl and TestPage the same thing happens. The same thing happens also in a completely new and separate project. I don't get it, this WAS working?
I have the follow form view:
<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 am building this simple quiz application using asp.net/vb.net and sql server for the database. Now what I want to happen is that when I click on submit button, it will count all the correct answers of the user based on the radio button he clicks.
I have two radio buttons and the correct answer for those two radio buttons is A, now if they click both A for those 2 radio buttons, they will get a score of two else if wrong, it won't count the incorrect answer.
Code:
Dim score As Integer = 0
If RbAnswers1.SelectedValue = "A" Then
For score = 0 To lbCorrectAnswerCount.Text.Count - 1
score += 1
Next score
If RbAnswers2.SelectedValue = "A" Then

When I click the Edit button in Gridview twice it'll always show the edit box or (textbox in gridview are editable)how to prevent that?
View 4 RepliesI have a FormView on my page that shows customer information and below that a GridView that shows the product keys associated with the selected customer. The selected customer is controlled by a QueryString parameter named id. The product key GridView and the FormView both check the id property of the QueryString and load the associated data. I have created a New LinkButton at the top of the page that utilizes the FormView.ChangeMode() method to set the FormView in Insert mode.
My problem is that when I set the FormView in Insert mode, the QueryString still contains the id parameter from the last selected customer so when the page loads to insert a new customer, the product keys for the last selected customer are loaded. Obviously a problem. Is there a way to clear the QueryString parameters in the New LinkButton click event? One thing that works is to clear the DataSourceID of the GridView and rebind the GridView and then when the new customer is inserted, set the DataSourceID again. Is this really the best way to accomplish this?
I have a datagrid on my aspx page (it is actually a user control on an aspx page). I dont ever want this datagrid to be editable. There is an Edit and a Delete link in the last column, so if you want to edit the data that are in the row you go to a new page for that purpose.
Let's say I have four rows in the grid. If I use the Delete link to delete the third row, when the page refreshes and the grid is rebuilt, the last row contains textboxes. I do not understand why this is happening. I was not the original author of this code (disclaimer).
This is the datagrid code on the ascx page:
Code:
<!-- PRINTER GRID -->
<asp:Panel ID="ShowListPanel" runat="server" Visible="true" CssClass="aspPanel">
<asp:Button ID="AddNewPrinter" runat="server" Text="Add New" />
<h1>My Printers</h1>
<asp:DataGrid ID="PrinterList"
[Code] ....
When I bind this grid to a dataset, what would be happening to create the last row with textboxes?
Code:
Sub BuildPrinterGrid()
Dim UserID As String = SFTools.FindUserID()
Dim outputDS As New DataSet
outputDS = SQLCalls.GetPrinterList(UserID)
PrinterList.DataSource = outputDS
[Code] ....
Note that there are two procedures that handle PrinterList.ItemDataBound. Is that unusual? I don't know if this is something obvious that I just am not seeing, or something lurking underneath seemingly correct code, but I don't understand how the textboxes are getting created.

I have created a page with a textbox and a button, when you enter a number in textbox and click on button, the onCommand event generates dynamic textboxes with dynamic requiredFieldValidators in the placeHolder and a newbutton. Now when I click on newButton, it does not validated dynamically generated textboxes, it does postback and every dynamic object disappear. The sample code is provided below.
