Dear Friend I have one Grid contain hyperlink control, i want to set its visibility depend on Login Group, If User is "Guest" then User can not access the link but if that user is "Authorized" he can access that link. For this, i have created following code Form Syntex Level Code:

public partial class frmTest : System.Web.UI.Page
{
private bool IsVisible
{
get { return (Session["G_UserGroup"] == "9") ? true : false; }
}
}

Form Design:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="frmTest.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

</head>
<body>
<form id="form1" runat="server">
<asp:GridView ID="gvwOrders" runat="server" AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" GridLines="None" AllowSorting="True" OnSorting="gvwOrders_Sorting" EnableViewState="False">

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="http://www.google.com"
Visible='<%# Eval("IsVisible") %>'>Link</asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<RowStyle BackColor="#EFF3FB" />
<EditRowStyle BackColor="#2461BF" />
<SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />

yes, it is right, are you facing any problem in this?

Lost User

why don't you set the visibiltiy to false in the method where you bind the grid? this is easier.

You have got to mark the property as public to access it from the markup. Change the "IsVisible" property's access specifier to "public" and your code will work. :) HTH!

I have change the property to public but still showing error "DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'IsVisible'."

Modify the gridview code where you set the visible property like this. Visible='<%# IsVisible %>'

hi! i've seen that you've solved your problem. but you can use also

<%=Server.HtmlEncode(IsVisible) %>

when you use IsVisible function to return a string :-D (parse true to "true" and false to "false") :laugh:
