You can do the checking on client side using JavaScript or...

Code:

<html>
<head>
	<title>Checkbox Checking Check Checker</title>
</head>
<body>

	<%
	Dim selected
	If Request.Querystring("checked") = "true" Then
		checked = "checked='checked'"
	Else
		checked = ""
	End If
	%>

	<form id="main_form" action="do_something.asp" method="post">
		<%
		Dim i
		For i = 0 To 10
		%>

		<input type='checkbox' name='some_name' value='<%=i%>' <%=checked%> />

		<%
		Next
		%>
	</form>

	<form id="checker" action="this_page.asp" method="get">
        <%
		If checked = "" Then
        %>
			<input type='hidden' name='checked' value='true' />
			<input type='submit' value='Check all' />
        <%
		Else
        %>
			<input type='hidden' name='checked' value='false' />
			<input type='submit' value='Uncheck all' />
        <%
		End If
        %>
	</form>

</body>
</html>

The method posted above does it server side. This is a good method because not all people will have JavaScript enabled.

Here's an example in JavaScript

Code:

<html>
<head>
    <title>Checkbox Checking Check Checker</title>
    <script language="JavaScript">
	    function checkThem(check) {
		    for (i=0; i<document.main_form.some_name.length; i++) {
			    document.main_form.some_name[i].checked = check;
		    }
	    }
    </script>
</head>
<body>

    <form name="main_form" action="do_something.asp" method="post">
	    <%
	    Dim i
	    For i = 0 To 10
	    %>

	    <input type='checkbox' name='some_name' value='<%=i%>' <%=checked%> />

	    <%
	    Next
	    %>

        <input type='button' name='CheckAll' value='Check All' onClick='checkThem(true)' />
        <input type='button' name='UncheckAll' value='Uncheck all' onClick='checkThem(false)' />
    </form>

</body>
</html>

Different spin on the same js method

Code:

<html>
<head>
    <title>Checkbox Checking Check Checker</title>
    <script language="JavaScript">
        function checkUnCheck() {
            var check;
            if (document.main_form.reCheck.value == "Check All") {
                check = true;
                document.main_form.reCheck.value = "Uncheck All";
            }
            else {
                check = false;
                document.main_form.reCheck.value = "Check All";
            }

		    for (i=0; i<document.main_form.some_name.length; i++) {
			    document.main_form.some_name[i].checked = check;
		    }
        }
    </script>
</head>
<body>

    <form name="main_form" action="do_something.asp" method="post">
	    <%
	    Dim i
	    For i = 0 To 10
	    %>

	    <input type='checkbox' name='some_name' value='<%=i%>' <%=checked%> />

	    <%
	    Next
	    %>

        <input type='button' name='reCheck' value='Check All' onClick='checkUnCheck()' />
    </form>

</body>
</html>
