Bind Image from database to LI element using C# and VB.Net in ASP.Net

Hello Sir,

Below is the code I am using to bind the image from the database to the li elements but here I am unable to bind to the data-thumb attribute of li.

Here I wanted to replace images/f2.jpg with the image binded for image ID=Image1 and same for the rest of li elements

Please help

                          <ul class="slides">
                              <li data-thumb="images/f2.jpg" >                                   
                                 <div class="thumb-image"> <asp:Image ID="Image1" runat="server" data-imagezoom="true" class="img-fluid" /> </div>
                              </li>
                              <li data-thumb="images/f1.jpg">
                                 <div class="thumb-image"> <asp:Image ID="Image2" runat="server" data-imagezoom="true" class="img-fluid" /> </div>
                              </li>
                              <li data-thumb="images/f3.jpg">
                                 <div class="thumb-image"> <asp:Image ID="Image3" runat="server" data-imagezoom="true" class="img-fluid" /> </div>
                              </li>
