Web Forms Label using code
We can make a Label using code also. For instance:
ASPX file:
As you can see, there are two Labels in this code. One Label is for TextBox and the other is for FileUpload. These Labels give instructions about there corresponding inputs.
<!DOCTYPE html>
<html>
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<div>
<asp:Label ID="Label1" runat="server" Text="User Name"></asp:Label>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</div>
<div>
<asp:Label ID="Label2" runat="server" Text="Upload a File"></asp:Label>
<asp:FileUpload ID="FileUpload1" runat="server" />
</div>
</div>
</form>
</body>
</html>
Output:
You can even set the Label properties from the C# file.
CS file:
In the following code, the Text property of Labels of ID Label1 and Label2 is set to “User Name” and “Upload a File” respectively.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Label1.Text="User Name";
Label2.Text="Upload a File";
}
}
