I want to create an asp.net ajax calendar like this, but entirely in code-behind. How do I do it?
Edit: I only want to add the js code to the page in code-behind (eg: not in the markup)
Edit_2: I need this because I create a textbox control in a template class and want to create the calendar there (for use with the textbox)
The ASP.NET ajax calendar you refer to is an extender, so in theory you could add it to your textbox at runtime in the code-behind. See the example below, the placeholder is vital!
I'm not sure why you would want to do this, can you give us a better idea of the need as there may be a better solution.
