Show and hide labels with assosicatedControls and their controls

Question

I want to show and hide a label and its control. I can do this in c# in the code behind. But, I can only show/hide the control. Any ideas?

<asp:label AssociatedControlID="thisLabel" runat="server">This:
     <asp:label ID="thisLabel" CssClass="ascontrol" runat="server" />
</asp:label>

I want to be able to show and hide that whole thing depending on what user gets to the page. I just need to know how to show/ hide that whole thing in the c# code behind...cannot seem to get the visibility of the wrapper label to go away.

Answer 1

You haven't supplied a server-side Id:

<asp:Label ID="label_MyControl" AssociatedControlID="txt_MyControl" runat="server" />
<asp:TextBox ID="txt_MyControl" runat="server" />

What you've done is nest a asp:Label control within another asp:Label control....

Answer 2

Since I normally hide more than one field contiguously, I tend to wrap the whole thing in an asp:Panel and hide the panel. However, that's just my particular usage. But since it's my usage, I tend to block those sorts of things out into panels even for something as simple as your example.

Just my nickel's worth, your mileage may vary, as always.

Answer 3

It should work if you get you r markup correct, like this:

<asp:Label ID="lblYear" runat="server" Text="Year (yyyy):" 
    AssociatedControlID="txtYear"></asp:Label>
<asp:TextBox ID="txtYear" runat="server" Columns="30" MaxLength="4"></asp:TextBox>

Then in the code behind you could have:

lblYear.visible = False
txtYear.Visible = False

Now, my understanding of the "AssociatedControlID" property of an asp:label is mainly for accessibility purposes. You don't need to have the AssociatedControlID value set to make things work as I've shown.
