                         <asp:Label ID="Label14T" runat="server" Text='<%# Eval("GroupName")%>' CssClass="ViewNG" 
                               Visible = '<%#Eval("GroupName").ToString() == "فروشندگان ملک"||"مستاجرین" ? true : false %>'></asp:Label>

<asp:Label ID="Label14T" runat="server" Text='<%# Eval("GroupName")%>' CssClass="ViewNG"

Visible = '<%#Eval("GroupName").ToString() == "فروشندگان ملک"||"مستاجرین" ? true : false %>'></asp:Label>

replace above code with below

<asp:Label ID="Label1" runat="server" Text='<%# Eval("GroupName")%>' CssClass="ViewNG"
Visible='<%#(Eval("GroupName").ToString() == "مستاجرین")||(Eval("GroupName").ToString() =="فروشندگان ملک")  ? true : false %>'></asp:Label>
