BindingSource的使用范例

public partial class Form1 : Form
{

private DataSet gDataSet = GetDS();
public Form1()
{
InitializeComponent();

// Set the data source to the DataSet.
bindingSource1.DataSource =gDataSet;

//Set the DataMember to the Menu table.
bindingSource1.DataMember = "Menu";

// Add the control data bindings.
neoDataGrid1.DataSource = bindingSource1;

neoTextBox1.TxtBox.DataBindings.Add("Text", bindingSource1,
"Beverages", true, DataSourceUpdateMode.OnPropertyChanged);
neoTextBox2.DataBindings.Add("Text", bindingSource1,
"Beverages", true, DataSourceUpdateMode.OnPropertyChanged);
bindingSource1.BindingComplete +=
new BindingCompleteEventHandler(bindingSource1_BindingComplete);

textBox1.DataBindings.Add("Text", bindingSource1,
"Beverages", true, DataSourceUpdateMode.OnPropertyChanged);
textBox2.DataBindings.Add("Text", bindingSource1,
"Beverages", true, DataSourceUpdateMode.OnPropertyChanged);
bindingSource1.BindingComplete +=
new BindingCompleteEventHandler(bindingSource1_BindingComplete);

}

public static DataSet GetDS()
{
DataSet set1 = new DataSet();
set1.Tables.Add("Menu");
set1.Tables[0].Columns.Add("Beverages");

// Add some rows to the table.
set1.Tables[0].Rows.Add("coffee");
set1.Tables[0].Rows.Add("tea");
set1.Tables[0].Rows.Add("hot chocolate");
set1.Tables[0].Rows.Add("milk");
set1.Tables[0].Rows.Add("orange juice");
return set1;

}

public void AddNewRow()
{

DataRow newRow = (DataRow)bindingSource1.AddNew(); //新增一行数据
newRow = ((DataRowView)this.bindingSource1.Current).Row; //取得新增的行
//newRow.aUIDField = Guid.NewGuid(); //修改数据
bindingSource1.ResetCurrentItem(); //刷新显示
}

private void bindingSource1_BindingComplete(object sender, BindingCompleteEventArgs e)
{
// Check if the data source has been updated, and that no error has occured.
if (e.BindingCompleteContext ==
BindingCompleteContext.DataSourceUpdate && e.Exception == null)

// If not, end the current edit.
e.Binding.BindingManagerBase.EndCurrentEdit();

}

private void neoButton1_Click(object sender, EventArgs e)
{

}
}
