程式 - [使用版本VB2008]DataGridView元件不連接資料庫使用

[魔術王子]

在Visual Basic語言中DataGridView是跟資料庫相關聯的元件
DataGridView可以將資料庫的資料列示出來,並且做修改
不過大家不曉得有沒有試過,不透過資料庫,來使用DataGridView做資料編輯
以下便是程式執行畫面,以及相關程式碼:

Form1.Designer.vb為設計元件的表單
Form1.resx為程式的資源檔
Form1.vb為這程式的程式碼

整個程式就是表單上插入ToolStrip元件和DataGridView元件,ToolStrip元件再加入6個ToolStripButton元件DataGridView元件要加入三個Column元件,StatusStrip元件可有可無,只是為了講解如何取得資料

DataGridView1.Rows.Add(資料1,資料2,資料3,...)為新增資料列的方法(註:資料數量要跟欄位數量相等)
DataGridView1.Rows.RemoveAt(Index)移除Index列資料
DataGridView1.Rows.Insert(Index,資料1,資料2,資料3,...)在Index列後面插入資料(註:資料數量要跟欄位數量相等)
DataGridView1.Rows(Index).Cells(0).Value取得Index列的第一欄資料
