Hi,

This is web forms ? Use "view source" but the client side id can be different depending on which option you are using. See https://docs.microsoft.com/en-us/aspnet/web-forms/overview/older-versions-getting-started/master-pages/control-id-naming-in-content-pages-cs#step-4-using-the-correctidattribute-value-in-client-side-script

You could use the ClientID property to use the proper name regardless on which option is used or use https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.control.clientidmode?view=netframework-4.7.2 if you want to take responsability on that...
