绑定源代码管理
Binding Source Control
我的表单中有绑定源代码管理。我利用表单中的绑定源 current_changed 事件来执行一些特殊任务,我面临的问题是,在 form_Load 事件中,我创建了一个列表作为该绑定源的数据源,并且 current_changed 事件已被多次调用。为什么会这样?
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
List<Employee> listEmployee = new List<Employee>();
for (int i = 1; i <= 10; i++)
{
Employee emp = new Employee();
emp.EmployeeName = "user" + i;
emp.EmployeeAddress = "Address" + i;
listEmployee.Add(emp);
}
bindingSource1.DataSource = listEmployee;
dataGridView1.DataSource = bindingSource1;
}
private void bindingSource1_CurrentChanged(object sender, EventArgs e)
{
MessageBox.Show("Hai");
}
}
public class Employee
{
private string Name;
private string Address;
public string EmployeeName {
get {return Name;}
set { Name = value; }
}
public string EmployeeAddress
{
get { return Address; }
set { Address = value; }
}
}
对于我的特殊情况,我在页面加载时创建了一个标志,并不止一次阻止了 currentchanged 事件的执行。我找不到任何其他方法来解决它。
