Naval,

If u want to generate textbox dynamically on button click

following is the code for .aspx side:

    <div>
    <asp:TextBox runat="server" ID="txtadd" ></asp:TextBox>
    <asp:Button ID="btnAdd" runat="server" Text="Create" onclick="btnAdd_Click" />
    <asp:Panel ID="pnlText" runat="server"></asp:Panel>
    </div>


code for code behind file:

     protected void btnAdd_Click(object sender, EventArgs e)
            {
                for (int i = 0; i < Convert.ToInt32(txtadd.Text); i++)
                {
                    TextBox txt = new TextBox();
                    txt.Width = 300;
                    txt.Height = 50;
                    txt.ID = "txtbox" + i;
                    txt.TextMode = TextBoxMode.MultiLine;
                    pnlText.Controls.Add(txt);
                }
            }

Hi,

Modifying few lines of code of above poster code:

In Aspx

 

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
	<title></title>
</head>
<body>
	<form id="form1" runat="server">
	<div>
		<asp:TextBox runat="server" ID="txtadd"></asp:TextBox>
		<asp:Button ID="btnAdd" runat="server" Text="Create" OnClick="btnAdd_Click" />
		<asp:Panel ID="pnlText" runat="server">
		</asp:Panel>
	</div>
	</form>
</body>
</html>



In Code Behind

 

using System;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace TestProject
{
    public partial class AddingControlsDynamically : System.Web.UI.Page
    {

        protected void btnAdd_Click(object sender, EventArgs e)
        {
            for (int i = 0; i < Convert.ToInt32(txtadd.Text); i++)
            {
                TextBox txt = new TextBox
                                  {
                                      Width = 300,
                                      Height = 50,
                                      ID = string.Format("txtbox{0}", i),
                                      TextMode = TextBoxMode.MultiLine
                                  };
                LiteralControl hcBreak = new LiteralControl ("<br/>");
                pnlText.Controls.Add(hcBreak);
                pnlText.Controls.Add(txt);
            }
        }
    }
}



And here is the output when you put 4 in textbox and press Create button

 

 

Thanks,

Raghav
