Use code like this:

<div>
<input id="Check1"  type="checkbox" runat="server" checked="checked"/> 
        CheckBox1 &nbsp;&nbsp;
    <span id="Span1" style="color:red" runat="server" />
    <br />
    <input type="button" id="Button1" value="Enter"
           onserverclick="Button1_Click" runat="server"/>
</div>

On Back End:

Sub Button1_Click(ByVal Source As Object, ByVal e As EventArgs)
    If Check1.Checked = True Then
        Span1.InnerHtml = "Check1 is checked!"
        Check1.Value = "Yes"
    Else
        Span1.InnerHtml = "Check1 is not checked!"
        Check1.Value = "No"
    End If
End Sub
