is there a way asp.net to trigger whether to display a fieldset?

I am creating a program with asp.net c#, i am using multiple gridviews to show different criteria of data on 1 page, each of these criteria has a title,

Now, if one of the gridviews happens to have no dat开发者_如何转开发a it will not show, however the title of the gridview will still be there as it is purely html fieldset and legend.

Are there any functions i could use to trigger the visibility of the title from the c# code?

Thanks (screenshot below)

You can add runat="server" to fieldset and set Visible = true or false as usual (of course you need to set an ID, too).

You can surround each grid in an <asp:Panel... with a visibility on the panel set to a server based property (e.g. Visibility=<%# RecordsReturnedGreaterThanZero %> so that the panel will only render the contents if there are some records returned in your query. Simply provide a property in your codebehind that acts as the boolean operator
