I have a datalist that populates records from database. In the datalist I have some labels and Linkbuttons that have set visibility to false. Now I want them to show on page load event based on some user defined functions that I have defined their stored procedure in the db. For instance I have a user defined function

void GetOnlinBooksForSale() Now when I call this function I would like to hide some labels while set the visibility of certain link button to true

What I have tried:

I tried this button am stcuk

void Visibility_ItemDataBound(object sender, DataListItemEventArgs e)
       {
           if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
           {
               LinkButton lnkbtnAddToCart = (LinkButton)e.Item.FindControl("lnkbtnAddToCart");
               LinkButton lnkkbtnRequest = (LinkButton)e.Item.FindControl("lnkkbtnRequest");
               Label lblNote = (Label)e.Item.FindControl("lblNote");
               Label lblRequested = (Label)e.Item.FindControl("blRequested");
               LinkButton lnkButtonRead = (LinkButton)e.Item.FindControl("lnkButtonRead");

           }

Here is my datalist

<asp:DataList ID="DataList1" runat="server" RepeatDirection="Horizontal" RepeatColumns="3">
                                   <HeaderStyle BackColor="Black" Font-Bold="true" Font-Size="Large" ForeColor="White" HorizontalAlign="Center" />
                                   <HeaderTemplate>ALL AVAILABLE BOOKS</HeaderTemplate>
                                   <ItemTemplate>
                                       <div style="width: 350px; text-align: left;font-size:small">
                                           "color: rgba(0, 0, 128, 1)" id="Book_nameLabel" width="100px" height="150px" class="row">  Add to Cart</asp:LinkButton>
                                               ^__b>
                                                   <asp:LinkButton ID="lnkButtonRead" Visible="false" CssClass="btn-outline-secondary" runat="server">Read (free)</asp:LinkButton>
                                               ^__b>

                                               ^__b>
                                                   <asp:Label ID="lblRequested" Visible="false" Style="color: #7d7d7d" runat="server" Text="Requested"></asp:Label>
