WINDEVWindows Mobile From version 16, data binding is offered on TreeView controls: the control can be directly linked to a data file or to a variable. See TreeView control linked to a variable or to a data file for more details.
By default, the TreeView control cannot automatically display the data coming from a data file.
Let's see some examples used to perform this operation.
This algorithm is used to fill a Treeview control from a data file:
// Read the file
HReadFirst(FileName, KeyName)
WHILE HOut() = False
// Add into the treeview
TreeAdd(NameTreeViewControl, MyRoot + TAB + Branch + TAB + Leaf)
HReadNext(FileName, KeyName)
END
Examples

Example 1

// Read the file
HReadFirst(Company, City)
WHILE HOut() = False
// Add into the treeview
TreeAdd(TreeViewControl, Company.City + TAB + Company.CompName)
HReadNext(Company, City)
END

Example 2

// Read the file
HReadFirst(Customer, CustName)
WHILE HOut() = False
// Add into the treeview
TreeAdd(TreeViewControl, Left(Customer.CustName, 1) + TAB + Customer.CustName)
HReadNext(Customer, CustName)
END

Example 3

// Read the file
FOR EACH Customer on CustName
// Add into the treeview
TreeAdd(TreeViewControl, Left(Customer.CustName, 1) + TAB + Customer.CustName)
END
