Show hidden div

Posted on 2006-11-28
Last Modified: 2008-03-17
I've placed all my validation summary erros into a hidden div on my ASP.NET pages. How would I go about showing this hidden div when there is an error? I've tried a couple of things but nothing seemed to work...either the div wasn't shown at all or part of the div was shown prior to any error coming up. I'm simply adding the div to the bottom of my main div.

If anyone has a good solution I'd like to see how they did this.

make your div runat server and set it's visability to false:

<div id="validationSummary" runat="server" visibility="False">



then in the code behind, if your page does not validate, simply do:

validationSummary.visible = True

hop it helps

Why don't you simply use a panel? That creates a DIV as well and is meant for such things. i.e.

<asp:Panel id="pnlErrors" runat="server" visible="false">
Errors go here

And in the code behind:

If (Page.IsValid = False) Then
    pnlErrors.Visible = True
    pnlErrors.Visible = False
    'Handle the form
End If

I've actually done this another way but it does involve the use of divs but I merely set the validator to Dynamic and have each validator held in a span which has a class applied to it effectively hidding it meantime.

Thanx anyway guys and I've split the points accordingly

BTW I already use asp:Panel within my code and find them very effective...great improvement over classic ASP.
