Question

I have a problem in my C# ASP.NET application, where the id and name tags are modified at runtime with a prefix ‘MainView_’ and ‘MainView$’ respectively. So my code:

<asp:Button ID='OKToContinueCheckInButton' runat='server' CausesValidation='False' Visibility='false' Style='display: none' OnClick='btnOKToContinueCheckIn' />  <script type='text/javascript'> <!--     var answer = confirm('Some Warning');     if (answer)         document.getElementById('OKToContinueCheckInButton').click(); // --> </script>  

becomes:

<input type='submit' name='MainView$OKToContinueCheckInButton' value='' id='MainView_OKToContinueCheckInButton' Visibility='false' style='display: none' />  <script type='text/javascript'> <!--     var answer = confirm('Some Warning');     if (answer)         document.getElementById('OKToContinueCheckInButton').click(); // --> </script> 

getElementID() returns null because the name has changed. Can anyone tell me why this occurs and if there is a way to possibly disable it from changing the id and name values. Thanks!

Answer 1

I think this would help you…

<script type='text/javascript'> <!--     var answer = confirm('Some Warning');     if (answer)         document.getElementById('<%= OKToContinueCheckInButton.ClientID %>').click(); // --> </script> 

This is the part that does the trick

<%= OKToContinueCheckInButton.ClientID %>
