Don’t mess with my textboxes
As I was putting together some quick ‘n dirty code to render some user controlled number of text boxes, I got this funny behavior.
This was the code for my aspx file:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1">
<div>
<asp:DropDownList ID="n" runat="server" AutoPostBack="true" OnSelectedIndexChanged="NSelectedIndexChanged">
<asp:ListItem Text="1" Value="1" />
<asp:ListItem Text="2" Value="2" />
<asp:ListItem Text="3" Value="3" />
<asp:ListItem Text="4" Value="4" />
<asp:ListItem Text="5" Value="5" />
<asp:ListItem Text="6" Value="6" />
<asp:ListItem Text="7" Value="7" />
</asp:DropDownList><br />
<% for(int i= 0; i < Total; i++) {%>
<asp:TextBox ID="txt" runat="server" Text="" /%><br /%>
<% }%>
</div>
</form>
</body>
</html>
and this was the code-behind:
using System;
using System.Web.UI;
public partial class _Default : Page
{
private int _total;
public int Total
{
get { return _total; }
set { _total = value; }
}
protected void NSelectedIndexChanged(object sender, EventArgs e)
{
_total = Convert.ToInt32(n.SelectedValue);
}
}
Now… when I run the app, and choose some value from the dropdown list it runs OK (beside all the text boxes having the same id). But when i select some, different value 2 or 3 times, some funny values (random number of ‘,’ come in to play on each of text box’s value).
I’m running Visual Studio 2005 here, targeting .NET Framework 2.0. Is the same happening to you ?
Here is the attached TestCode.
And do you have an explanation for this funny behavior?
Nope
Oi Paulo,
olha deve ser um problema do asp.net a tua rotina esta correcta
corrigi o problema fazendo uma pequena alteração:
alterei o objecto asp.net textbox para um input type text
fica bem e bom natal.
Untitled Page
<% for(int i= 0; i
na linha 21 altera de:
para
e desaparece esse situação anormal
Certo, mas a questão não é mudar de asp.net server controls para html server controls. Este comportamento é estranho, mas é by design. Desculpa lá o atraso, mas só agora vi os comentários.
