最近在msdn看到此範例,沒用過CurrencyManager

小弟就用範例介紹如何使用CurrencyManager

c#(winform)

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace WindowsApplication1 { public partial class TestCurrencyManager : Form { private DataTable myTable = new DataTable("Table"); private CurrencyManager myCurrencyManager; public TestCurrencyManager() { InitializeComponent(); } private void TestCurrencyManager_Load(object sender, EventArgs e) { InitData(); BindTextBox(); } //初始資料 private void InitData() { myTable.Columns.Add("Name", typeof(String)); DataRow row; for (int i = 1; i <= 10; i++) { row = myTable.NewRow(); row["Name"] = "puma" + i; myTable.Rows.Add(row); } } //Bind Textbox private void BindTextBox() { this.textBox1.DataBindings.Add("Text", myTable, "Name"); myCurrencyManager = this.BindingContext[myTable] as CurrencyManager; myCurrencyManager.Position = 0; } //MoveFirst private void btnMoveFirst_Click(object sender, EventArgs e) { myCurrencyManager.Position = 0; } //MovePrevious private void btnMovePrevious_Click(object sender, EventArgs e) { if (myCurrencyManager.Position == 0) { MessageBox.Show("已經第一筆"); } else { myCurrencyManager.Position -= 1; } } //MoveNext private void btnMoveNext_Click(object sender, EventArgs e) { if (myCurrencyManager.Position == myCurrencyManager.Count - 1) { MessageBox.Show("已經最後筆"); } else { myCurrencyManager.Position += 1; } } //MoveLast private void btnMoveLast_Click(object sender, EventArgs e) { myCurrencyManager.Position = myCurrencyManager.Count - 1; } } }

執行結果:
