向DataGridView添加一行 [英] add a row to DataGridView

问题描述

我想以编程方式向DataGridView添加一行(数据源为
与它绑定)，但是当我调用方法DataGridView.Rows.Add时，会出现一个
System.InvalidOperationException将被抛出，错误消息是:
行不能以编程方式添加到DataGridView的行中
控件绑定数据时进行收集.

I want to programmatically add a row to DataGridView (a datasource was
binded with it), but when I call the method DataGridView.Rows.Add, a
System.InvalidOperationException will be thrown and the error message is:
Rows cannot be programmatically added to the DataGridView''s rows
collection when the control is data-bound.

private void add_click(object sender, EventArgs e)
{
 try
 {
    DataRow row = db1.NewRow();
    dataGridView2.Rows.Add(dataGridView2.CurrentRow.Index);
    sda.Update(db1);
 }
 catch (Exception exceptionObj)
 {
   System.Windows.Forms.MessageBox.Show(exceptionObj.Message.ToString());
 }

}

What code change should be done to dynamically add a row to datagrid when it is bound to data source.?
