Double tree node C# net Ztree linqtosql source code

Architecture design module architecture

 As a result, the tree on the left side of the operation refreshes the tree on the right side asynchronously


Need to be used from it

 JS 

ajax 

ztree  

js calls C# background method 

Recursion 

JS callback function

linqtosql

C# basic knowledge


Note: The standard object mode used by the article's ztree 

There are two ways to use ztree, both of which have great requirements for database design 

Mainly have ID and ParentID

When using the simple object mode, you need to pay attention to adding an ISparent field to determine whether it is a node

The following is the source code using the standard object model

        public List<Company_childrenweb> children
        {
            get { return _children; }
            set { _children = value; }
        }

        private string _cId;

        public string cId
        {
            get { return _cId; }
            set { _cId = value; }
        }
        private string _cName;

        {
            get { return _cParentId; }
            set { _cParentId = value; }
        }

        {
            get { return _cUrl; }
            set { _cUrl = value; }
        }

        public string cParentrightID
        {
