The WijDialog control can be used to display custom HTML content. Complete these steps:

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. Add the following markup to create a dialog window with custom HTML content:

      <div>
   

         <div id="dialog" title="Custom HTML">
   

           <h2> HTML Content</h2><p>&nbsp;You can add custom HTML content.
   

           <br /></p>&nbsp;Enter text here: <input type="text" id="input1" />
   

           <br/>&nbsp;And then click: <input type="button" value="Show" onclick="alert(document.getElementById('input1').value)" />
   

         </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. Run your application. Your dialog box should resemble the following image. You can enter text and click Show to show an alert dialog box.
