Hey Need help i tried to bind controls ID throw dropdownlist onchange fucntion this code:

<br />
<pre lang="xml"><br />
<br />
<asp:DropDownList ID="ddlItemtype" runat="server"<br />
                                       CssClass="Small-dropdown" onchange="CheckToEnableDDL(''<%=ddlItemtype.ClientID %>'',''<%=ddlItemsList.ClientID %>'' );"<br />

</pre><br />
<br />

但是结果在源代码中
是

but the result in the source code

<br />
<br />
<pre lang="xml"><br />
<select name="ctl00$ContentPlaceHolder1$ddlItemtype" id="ctl00_ContentPlaceHolder1_ddlItemtype" class="Small-dropdown" onchange="javasctipt:CheckToEnableDDL(''&lt;%=ddlItemtype.ClientID %>'',''&lt;%=ddlItemsList.ClientID %>'' );"><br />
        <option selected="selected" value="1">--Choose--</option><br />
        <option value="0">بند جزئي</option><br />
        <option value="2">بند وصفي</option><br />
<br />
    </select><br />
</pre><br />
