Hi, I want to develop an application using C# winforms to show multiples forms in single page. Here I want to show different forms in MDI parents on button click. There will be list of buttons for each form located in MDI page where it can swap between the forms by clicking on respective buttons so that it can toggle between buttons to show multiple forms. Each form may have 20 controls. In some of controls data will be loaded from database.I have used tabs but I found performance issue. Can anyone suggest me the best solutions
