asp.net micro-credit development (user group Management) _ Practical skills

The previous article has explained to the new user group, moves the user to the grouping function, this chapter mainly explains modifies the grouping name and deletes the grouping

Directly on the code, nonsense not to say, get the entity classes that you want to use for a grouped list

 <summary>
 ///Sub-group class
 ///</summary> public
 class Wxgroupsinfo
 {public
  string group_id {get; set;} Group numbering public
  string Group_name {get; set;} Group name Public
  string Group_count {get; set;} Group number
 }

Modify a page for a grouped name

Foreground code:

This article has been sorted out to the ASP. NET micro-Credit Development tutorial Summary, you are welcome to learn to read.

The above is the user group management of all the core code, only for reference, I hope to help you learn.
