The WijDialog control allows you to easily create Modal Alert windows.

1. Create an ASP.NET Web application with a ScriptManager control and install Juice UI and the Wijmo Juice libraries to your project via NuGet.
2. Add a standard Panel control to the main content of your page.
3. Insert the following markup within the Panel markup to create the dialog window:

           
      <div>  
           <div id="dialog-message" title="Download complete">        
               <p>       
                   <span class="ui-icon
           ui-icon-circle-check"></span>Your files have uploaded successfully!       
               </p>        
           </div>        
      </div>
                   
   

4. Use the following markup to add a WijDialog control to the page and set the TargetControlID to Panel1.

           
     <cc1:WijDialog ID="Panel1_WijDialog" runat="server"        
           TargetControlID="Panel1">        
     </cc1:WijDialog>
                   
   

5. Select View | Properties Window in the Visual Studio menu.
6. Click the drop-down list at the top of the Properties window and select Panel1_WijDialog.
7. Set the Modal property to True.
8. Set the Title property to Download complete. Your markup should look similar to this:

           
   <cc1:WijDialog ID="Panel1_WijDialog" runat="server"        
           CloseOnEscape="False" Show="blind" TargetControlID="Panel1" Modal="True" Title="Download
           complete">        
   </cc1:WijDialog>
                   
   

9. Run your application to see the Alert Window. It should resemble the following image:
