User control in asp.net + java script + validation
I created a user control for Countries using Microsoft Visual sutdio. I populated a dropdownlist ( Server Side ) using database and then I called this countrol in one of my web form. I wanted to validate this User control but it was not validating when I used ”MyControl1.ClientID” instead of this when i Use Asp.Net generated ID it worked. Can any one tell me why It happend.?<script type=”text/javascript”>
function textlen(source,arguments){var textlen=document.getElementById(“<%=TextBox1.ClientID%>”).value; var country=document.getElementById(‘ctl00_ContentPlaceHolder1_Country1_DropDownListCountries’).value; if (country==“Select a value” && textlen.length==0){arguments.IsValid=
false; return;}}</script>
This is my user control id “ctl00_ContentPlaceHolder1_Country1_DropDownListCountries” Javascript was unable to get User control Id by using the following line
var country=document.getElementById(Country1.ClientID‘).value;
 Does any one know why?
