.NET wants to control my Visibility!

Ok, so I want to hide a control, label or block, I put it runat=”server” and on the server-side I simply do MyControl.Visible = false right? Well sure, that will simply not render the whole block on the client-side. What if you then want to make the visibility back up? You need to do a full postback, yikes!

Another option is to use MyControl.Style and change the visibility client-side, something like this:

<asp:Label ID="MyLabel" runat="server">Whatever. Bla Bla Bla...</asp:Label>

On the server-side code, we then do this instead: 

MyLabel.Style["display"] = "none";

And on the client-side, we can toggle it back to visible like this: 

document.getElementById('<%= MyLabel.ClientID %>').style.display='block';
