Question

I am trying to hide a data field if it is null via ASP.NET.
I have the following setup:

<script runat="server" type="text/vb">
// target the id called test
var test = document.getElementById("test");

// if test is not empty, show
// else hide test
if (test.value != null){
    document.getElementById("test").style.visibility = visible;
}else{
    document.getElementById("test").style.visibility = hidden;
}

<p><asp:Label runat="server" id="test"><%# Eval("DBField")%></asp:Label></p>

Am I way off here? I am getting error in whatever I try. I don’t think it should be so complicated however…any thoughts/recommendations would be greatly appreciated.

Thank you in advanced,

I was able to hide data via the following code:

<asp:PlaceHolder ID="PlaceHolder" runat="server" Visible='<%# IIf((Eval("test")).ToString().Length > 0, "true", "false") %>'>
     <h3>test</h3>
     <asp:Label ID="test" runat="server" Text='<%# Bind("test") %>'></asp:Label>
</asp:PlaceHolder>
