Unable to write to asp.net textbox control with the html5 “date” type

Question

I have an asp.net page with a an html5 TextBox control set as the \"date\" type. The control on my page looks like this:

Answer 1

This is actually the correct way to set the date but the format was wrong!

TextBoxMyDate.Text = DateTime.UtcNow.ToString("yyyy-MM-dd");

I was confusing how the browser displays the date and the html5 standards for this control!

Answer 2

Yes, it is quite possible. Here is an example of a date selection filter with ajaxcontrotoolkit and the textbox field.
