Clone Group/Rule in ASP.NET MVC Query builder control

14 Jun 202411 minutes to read

The Query Builder functionality extends to cloning both individual rules and entire groups. Utilizing the Clone options will generate an exact duplicate of a rule or group adjacent to the original one. This feature enables users to replicate complex query structures effortlessly. The ShowButtons function offers users the ability to toggle the visibility of these cloning buttons, providing convenient control over the cloning process within the Query Builder interface.

       col.Field("TitleOfCourtesy").Label("Title Of Courtesy").Type("boolean").Values(new List<string> { "Mr.", "Mrs." }).Add();
