How to create a Dialog like in Winforms for the website?

To create a dialog-like experience similar to WinForms in a web application using ASP.NET, you can use a modal dialog (popup) to display search results and allow users to select an object.

Example: ASPX

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="SearchPage.aspx.cs" Inherits="YourNamespace.SearchPage" %>




    
    
    
    


    

        

            

                
            
            
        

        
        

            

                

                    

                        
Select an Object
                        
                            ×
                        
                    
                    

                        
                            
                                

                                    <%# Eval("ObjectName") %>
                                    Select
                                
                            
                        
                    
                    

                        
                        Cancel
