Question

I have an ASP.NET text control “FromDate” whose visible property is set to false, but I wanted a client side javascript to be able to toggle the visibility property using CSS properties

element1.style.display = "none"; // hides the element
element1.style.display = ""; // shows the element

but when I attempt to get the textbox, I get null on

  var element1 = document.getElementById("FromDate");

When I try the same code with visble=true as the default on the “FromDate” ASP.NET control, it works (although that is not the behavior I need)

Any ideas?

If you want to hide this control, you can try CSS like this:

<asp:somecontrol id="FromDate" style="display:none" />

I think hiding the control with CSS is easier to understand.
