示例1: BindControls
protected void BindControls()
{
/* Create two Binding objects for the first two TextBox
controls. The data-bound property for both controls
is the Text property. The data source is a DataSet
(ds). The data member is specified by a navigation
path in the form : TableName.ColumnName. */
textBox1.DataBindings.Add(new Binding
("Text", ds, "customers.custName"));
textBox2.DataBindings.Add(new Binding
("Text", ds, "customers.custID"));
/* Bind the DateTimePicker control by adding a new Binding.
The data member of the DateTimePicker is specified by a
navigation path in the form: TableName.RelationName.ColumnName. */
DateTimePicker1.DataBindings.Add(new
Binding("Value", ds, "customers.CustToOrders.OrderDate"));
/* Create a new Binding using the DataSet and a
navigation path(TableName.RelationName.ColumnName).
Add event delegates for the Parse and Format events to
the Binding object, and add the object to the third
TextBox control's BindingsCollection. The delegates
must be added before adding the Binding to the
collection; otherwise, no formatting occurs until
the Current object of the BindingManagerBase for
the data source changes. */
Binding b = new Binding
("Text", ds, "customers.custToOrders.OrderAmount");
b.Parse += new ConvertEventHandler(CurrencyStringToDecimal);
b.Format += new ConvertEventHandler(DecimalToCurrencyString);
textBox3.DataBindings.Add(b);
/*Bind the fourth TextBox to the Value of the
DateTimePicker control. This demonstrates how one control
can be bound to another.*/
textBox4.DataBindings.Add("Text", DateTimePicker1,"Value");
BindingManagerBase bmText = this.BindingContext[
DateTimePicker1];
/* Print the Type of the BindingManagerBase, which is
a PropertyManager because the data source
returns only a single property value. */
Console.WriteLine(bmText.GetType().ToString());
// Print the count of managed objects, which is 1.
Console.WriteLine(bmText.Count);
// Get the BindingManagerBase for the Customers table.
bmCustomers = this.BindingContext [ds, "Customers"];
/* Print the Type and count of the BindingManagerBase.
Because the data source inherits from IBindingList,
it is a RelatedCurrencyManager (derived from CurrencyManager). */
Console.WriteLine(bmCustomers.GetType().ToString());
Console.WriteLine(bmCustomers.Count);
/* Get the BindingManagerBase for the Orders of the current
customer using a navigation path: TableName.RelationName. */
bmOrders = this.BindingContext[ds, "customers.CustToOrders"];
