The ListViewContentCustom() method enables you to load the content of a ListView from a file. We recommand 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) {...}
Valeur Paramètre 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) {...}
Valeur Paramètre Description
ListView listView ListView to load the content to
string filePath The file location where the content is
string itemSplit The element sparator
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 writting Load.ListViewContentCustom, it is written LeoCorpLibrary.Load.ListViewContentCustom. This because of a conflict with Load which is an event in Windows Forms.
