Question

I need this asp:TableRow to show conditionally.

<asp:TableRow>
    <asp:TableCell><asp:Label id="ExtraAmountType" runat="server" Width="182px"></asp:Label></asp:TableCell>
    <asp:TableCell Width="10%" HorizontalAlign="Right">$&nbsp;<asp:textbox id="MembershipDues" runat="server" Wrap="False" BackColor="#FFFF80" AutoPostBack="True" Width="31px" MaxLength="3" ontextchanged="MembershipDues_TextChanged"></asp:textbox></asp:TableCell>
</asp:TableRow>

How can I do this. I wrapped it in an

<asp:PlaceHolder ID="memberdues" runat="server"> 

tag but it complains:

Error 12 System.Web.UI.WebControls.TableRowCollection must have items of type ‘System.Web.UI.WebControls.TableRow’. ‘asp:PlaceHolder’ is of type ‘System.Web.UI.WebControls.PlaceHolder’.

I need this row to show conditionally.

I do this in Page_Load:

memberdues.Visible = false; 
if (DuesInfo.CredentialsAmount > 0)
{
    // do some other stuff to populate the variables in the placeholder then show it
    memberdues.Visible = true; 
}

Answer 1

Give it an ID and set its runat to server then you can access it from code behind.

<asp:TableRow runat="server" ID="rowExtraAmountType">

Now it’s accessible from an event from behind:

rowExtraAmountType.Visible = (conditional expression);

Edit: Shown below with your question edits

<asp:TableRow runat="server" ID="memberdues">

Then the code behind:

memberdues.Visible = (DuesInfo.CredentialsAmount > 0);
