Warning

We recommend that you use either ListViewContentXML or ListViewContentJson instead of our custom system which is old and outdated.

a. Required configuration

To use the following methods, you need to use the version 1.7 or higher of LeoCorpLibrary, and put this at the top of your code file:

C#

b. How it works

To understand how the system works, read save system.

1. The system is going to read the file
2. The system is going to separate the elements

4. From each "row", it will generate a ListViewItem.
5. Then it loads the ListViewItem inside the specified ListView.

The ListViewContentCustom() method enables you to load the content of a ListView from a file. We recommend that you se these following parameters for your ListView:

• Details vue mode
• FullRowSelect = true

There is two variations of the method:

Variation 1

LeoCorpLibrary.Load.ListViewContentCustom(ListView listView1, string filePath) {...}

Value	Argument	Description
ListView	listView	The ListView to load the content to
string	filePath	The file location where the content is

Variation 2

LeoCorpLibrary.Load.ListViewContentCustom(ListView listView1, string filePath, string itemSplit, string columnSplit) {...}

Value	Argument	Description
ListView	listView	ListView to load the content to
string	filePath	The file location where the content is
string	itemSplit	The element separator
string	columnSplit	The column separator

Here's an example of usage:

C#

// Variation 1
LeoCorpLibrary.Load.ListViewContentCustom(listView1, @"C:\content.txt");

// Variation 2
LeoCorpLibrary.Load.ListViewContentCustom(listView1, @"C:\content.txt", "/*E*/", "/*C*/");

VB

' Variation 1
LeoCorpLibrary.Load.ListViewContentCustom(ListView1, "C:/content.txt")

' Variation 2
LeoCorpLibrary.Load.ListViewContentCustom(ListVew1, "C:/content.txt", "/*E*/", "/*C*/")

Note

In the examples, you might noticed that instead of simply writing Load.ListViewContentCustom, it is written LeoCorpLibrary.Load.ListViewContentCustom. This because of a conflict with Load which is an event in Windows Forms.
