How to disable and Enable TextBox acording to checklbox

<asp:CheckBox ID="htmlChkNotify开发者_StackOverflow中文版" runat="server" OnCheckedChanged="ToggleTextBox(this,'htmlTxtNotifyemailaddress')" />  
<asp:TextBox ID="htmlTxtNotifyemailaddress" runat="server" Enabled="false"></asp:TextBox>  

function ToggleTextBox(CheckBox, TextBoxID) {

     var TextBox = document.getElementById(TextBoxID);  
     if (CheckBox.checked) {  
         TextBox.disabled = false;  
         TextBox.value = "";  
     }  
     else {  
         TextBox.disabled = true;  
         TextBox.value = "";  
     }  
 }

OnCheckChanged is expecting an ASP.Net event handler, it's not for JavaScript, for that attach your event handler like this:

htmlChkNotify.Attributes.Add("onclick",  
   "ToggleTextBox(this,'" + htmlTxtNotifyemailaddress.ClientID + "');");

I broke it down to 2 lines for readability here only, but the idea is to generate an onclick inline handler, rather than the server-side event handler it's currently trying to bind, in a place it can't pass this (which is why the parser fails).
