ASP VB.NET CheckBox CheckedChanged Event
Here’s a small example of how to make a checkbox change a label property:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %>
<!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></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:CheckBox ID="CheckBox1" runat="server" Text="Make the Label Change!" AutoPostBack="True" />
<br />
<br />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</div>
</form>
</body>
</html>
Here’s the VB Codebehind:
Partial Class Default2
Inherits System.Web.UI.Page
Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
If CheckBox1.Checked = True Then
Label1.ForeColor = Drawing.Color.Red
Label1.Text = "This is True and Red"
Else
Label1.ForeColor = Drawing.Color.Green
Label1.Text = "This is Else<br /> and Green"
End If
End Sub
End Class
