I am having trouble controlling a radtextbox. I have a radcombobox(ddlMaritalStatus) and a radtextbox(txtSpoueName) on my page. What I would like is that when a user selects "Single" from ddlMaritalStatus then txtSpouseName becomes disabled. My problem is that if a user selects "Married" and starts to type in txtSpouseName but then changes ddlMaritalStatus to "Single" the text is still in txtSpouseName. So how do I make it so that if user selects "Single" then txtSpouseName becomes disabled and any text is erased and when user selects "Married" txtSpouseName becomes enabled again?
<p>
<telerik:RadComboBox ID="ddlMaritalStatus" runat="server" EmptyMessage="--Select--" OnClientSelectedIndexChanged="DisableBox" TabIndex="15" AutoPostBack="false"></telerik:RadComboBox>
<script type="text/javascript">
function DisableBox(sender, args) {
var TextBox = $find("<%=txtSpouseName.ClientID %>");
if (sender.get_selectedItem().get_value() == "Single") {
document.getElementById(sender.get_id().replace("ddlMaritalStatus", "txtSpouseName")).value = "";
//document.getElementById("txtSpouseName").disabled=true;
document.getElementById("txtSpouseName").setAttribute("Enabled", "False");
}
else {
document.getElementById(sender.get_id().replace("ddlMaritalStatus", "txtSpouseName")).value = "";
//document.getElementById("txtSpouseName").disabled = false;
document.getElementById("txtSpouseName").
}
}
</script>
<asp:RequiredFieldValidator ID="MaritalStatusValidator" runat="server" ErrorMessage="Please Select" ControlToValidate="ddlMaritalStatus"></asp:RequiredFieldValidator>

<telerik:RadTextBox ID="txtSpouseName" runat="server" Enabled="false" AutoPostBack="false" TabIndex="16"></telerik:RadTextBox>
<asp:RegularExpressionValidator ID="SpouseNameValidator" runat="server" ErrorMessage="First (Initial) Last" ValidationExpression="[A-Z][a-z]+ ?[A-Z]? ([A-Z][a-z]?')?([A-Z][a-z]+?-)?[A-Z][a-z]+" ControlToValidate="txtSpouseName"></asp:RegularExpressionValidator>

My script is not working
