Menu
Hi i am using ajax in asp.net
i am using tab container and tap panel controls.
i am trying to add tab panels dynamically on button click.
my form code is
<%@ Page Language=”C#” AutoEventWireup=”true” CodeFile=”Default.aspx.cs” Inherits=”_Default” %>
<%@ Register Assembly=”System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35″
Namespace=”System.Web.UI” TagPrefix=”asp” %>
<%@ Register Assembly=”AjaxControlToolkit” Namespace=”AjaxControlToolkit” TagPrefix=”cc1″ %>
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “
<html xmlns=”
<head runat=”server”>
<title>Untitled Page</title>
</head>
<body>
<form id=”form1″ runat=”server”>
<div>
</div>
<asp:ScriptManager ID=”ScriptManager1″ runat=”server”>
</asp:ScriptManager>
<cc1:TabContainer ID=”TabContainer1″ runat=”server” Width=”600″>
<cc1:TabPanel ID=”TabPanel1″ runat=”server” HeaderText=”tab1″>
<ContentTemplate>
<asp:Button ID=”asd” runat=”server” Width=”30″ />
</ContentTemplate>
</cc1:TabPanel>
<cc1:TabPanel ID=”TabPanel2″ runat=”server” HeaderText=”tab2″>
</cc1:TabPanel>
</cc1:TabContainer>
<asp:Button ID=”Button1″ runat=”server” OnClick=”Button1_Click” Text=”Button” />
</form>
</body>
</html>
page code: (.cs file)
public partial class _Default : System.Web.UI.Page
{
int i = 0;
AjaxControlToolkit.TabPanel tp;
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
i = i + 1;
tp = new AjaxControlToolkit.TabPanel();
tp.ID = “tp” + i.ToString();
Button b = new Button();
b.ID = “b” + i.ToString();
tp.Controls.Add(b);
tp.HeaderText = “i am new” + i.ToString();
TabContainer1.Controls.Add(tp);
}
}
i am able to add one tab dynamically but when i click the buttion second time, i am getting
“Specified argument was out of the range of valid values.
Parameter name: index “
error.
any help?
Thank you
