问题

i have a dataview with:

<asp:BoundField DataField="AccontoAutorizzato" HeaderText="Acconto Aut." 
                        SortExpression="AccontoAutorizzato" dataformatstring="{0:C}"  />

is possible hide the values of each with a condition like

 Visible=<%# ((Int32)Eval("StatoID") < 2) %>

It's possible with following

<asp:TemplateField HeaderText="Acconto Aut." >
     <ItemTemplate>
          <asp:Label ID="lbl" runat="server" Text='<%# Bind"AccontoAutorizzato") %>'
                        Visible='<%# ((int)(Eval("StatoID")) < 2) %>' />
     </ItemTemplate>
</asp:TemplateField>

Saar's answer did not work for me, because even though the binding should return a true or false, the interpreter could not actually convert the condition result to a Boolean value.

So instead, I used an explicit choice of Boolean values:

<asp:TemplateField HeaderText="Acconto Aut." >
     <ItemTemplate>
          <asp:Label ID="lbl" runat="server" Text='<%# Bind"AccontoAutorizzato") %>'
                        Visible='<%# ((int)(Eval("StatoID")) < 2) ? Convert.ToBoolean(0) : Convert.ToBoolean(1) %>' />
     </ItemTemplate>
</asp:TemplateField>

I hope this makes it easier for others struggling with the Boolean error when applying it to a Visible property.
