1、datagridview綁定數(shù)據(jù)源的幾種常見方式datagridview綁定數(shù)據(jù)源的幾種常見方式/開始以前，先認(rèn)識一下WinForm控件數(shù)據(jù)綁定的兩種形式，簡單數(shù)據(jù)綁定和復(fù)雜數(shù)據(jù)綁定。 /1）簡單數(shù)據(jù)綁定 /using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings"connStr".ToString() / / SqlDataAdapter sda = new SqlDataAdapter("Select * Fr

2、om T_Class Where F_Type='Product' order by F_RootID,F_Orders", conn); / DataSet Ds = new DataSet(); / sda.Fill(Ds, "T_Class"); / /使用DataSet綁定時，必須同時指明DateMember / /this.dataGridView1.DataSource = Ds; / /this.dataGridView1.DataMember = "T_Class"

3、; / /也可以直接用DataTable來綁定 / this.dataGridView1.DataSource = Ds.Tables"T_Class" / /簡單的數(shù)據(jù)綁定是將用戶控件的某一個屬性綁定至某一個類型實例上的某一屬性。采用如下形式進(jìn)行綁定：引用控件.DataBindings.Add("控件屬性", 實例對象, "屬性名", true); /2）復(fù)雜數(shù)據(jù)綁定 /復(fù)雜的數(shù)據(jù)綁定是將一個以列表為基礎(chǔ)的用戶控件（例如：ComboBox、ListBox、ErrorProv

4、ider、DataGridView等控件）綁定至一個數(shù)據(jù)對象的列表。 /基本上，Windows Forms的復(fù)雜數(shù)據(jù)綁定允許綁定至支持IList接口的數(shù)據(jù)列表。此外，如果想通過一個BindingSource組件進(jìn)行綁定，還可以綁定至一個支持IEnumerable接口的數(shù)據(jù)列表。 /對于復(fù)雜數(shù)據(jù)綁定，常用的數(shù)據(jù)源類型有（代碼以DataGridView作為示例控件）： using System; using System.Collections.Generic; using System.ComponentModel; using Sys

5、tem.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Collections; namespace DataGridViewBindingData  public partial class Form1 : Form  public Form1()  InitializeComponent();  private void button1

6、_Click(object sender, EventArgs e)  /this.dataGridView1.DataSource = DataBindingByList1(); /this.dataGridView1.DataSource = DataBindingByList2(); /this.dataGridView1.DataSource = DataBindingByDataTable(); this.dataGridView1.DataSource = DataBindingByBindingSource(); 

7、60;/ <summary> / IList接口（包括一維數(shù)組，ArrayList等） / </summary> / <returns></returns> private ArrayList DataBindingByList1()  ArrayList Al = new ArrayList(); Al.Add(new PersonInfo("a","-1"); Al.Add(new PersonInfo("b&qu

8、ot;,"-2"); Al.Add(new PersonInfo("c","-3"); return Al;  / <summary> / IList接口（包括一維數(shù)組，ArrayList等） / </summary> / <returns></returns> private ArrayList DataBindingByList2()  ArrayList list = new Arr

9、ayList(); for (int i = 0; i < 10; i+)  list.Add(new DictionaryEntry(i.ToString(),i.ToString()+"_List");  return list;  / <summary> / IListSource接口（DataTable、DataSet等） / </summary> / <returns></returns> privat

10、e DataTable DataBindingByDataTable()  DataTable dt = new DataTable(); DataColumn dc1 = new DataColumn("Name"); DataColumn dc2 = new DataColumn("Value"); dt.Columns.Add(dc1); dt.Columns.Add(dc2); for (int i = 1; i <= 10; i+)  DataRow

11、 dr = dt.NewRow(); dr0 = i; dr1 = i.ToString() + "_DataTable" dt.Rows.Add(dr);  return dt;  / <summary> / IBindingListView接口（如BindingSource類） / </summary> / <returns></returns> private BindingSource DataBindingB

12、yBindingSource()  Dictionary<string, string> dic = new Dictionary<string, string>(); for (int i = 0; i < 10; i+)  dic.Add(i.ToString(),i.ToString()+"_Dictionary");  return new BindingSource(dic,null);    /上面代碼中BindingSource的Datasource是一個結(jié)構(gòu)類型DictionaryEntry，同樣的DictionaryEntry并不能直接賦值給Combobox的DataSource，但通過BindingSource仍然可以間接實現(xiàn)。 / 這是因為： /BindingSource可以作為一個強類型的數(shù)據(jù)源。其數(shù)據(jù)源的類型通過以下機制之一固定： /· 使用 Add 方法
