I am using c# MVC 4 and I would like to create Multiple user controls and fill data dynamically.

Eg: I have a history filling form and in it i have to display multiple question having options control which can be radio button or check box also have a text-area with every question.So I do not know the field names and its control types prior to visiting this page, it gets the data and control types from a sql table with question:

field 1: Text-Label

field 2: DropdownList (values: 1,2,3,4,5) or radio button or check-box or text-box

field 3: textarea

How do I achieve this?

推荐答案

亲爱的，



您可以使用模板来实现此目的。您可以在共享文件夹下创建显示或编辑器模板。可以基于来自SQL的控件名称来命名模板。因此对于例如你有三个来自SQL的控件名 - TextArea，RadioButton和CheckBox。因此，当您调用Displayfor或Editorfor辅助方法时，它会分别尝试分别在文件夹Views / Shared / DisplayTemplates或Views / Shared / EditorTemplates下查看文件（TextArea.cshtml等）。如果您在实施过程中遇到任何问题，请告诉我。

Hi Honey,

You can use templates to achieve this. You can create display or editor templates under shared folder. Naming of the template can be done based on the control name coming from SQL. So for e.g. u have three control names coming from SQL - TextArea, RadioButton and CheckBox. So when you call Displayfor or Editorfor helper methods it wud try to see files (TextArea.cshtml etc.) under folders Views/Shared/DisplayTemplates or Views/Shared/EditorTemplates respectively respectively. Please let me know if you face any issue while implementing it.
