我正在为 ListView 使用一些类似的东西。 方法是：
创建TextBox，添加到Controls数组中，并隐藏一个。
innerTextBox.Size = new Size(0, 0);
innerTextBox.Location = new Point(0, 0);
this.Controls.AddRange(new Control[] { this.innerTextBox });
innerTextBox.KeyPress += new KeyPressEventHandler(this.EditOver);
innerTextBox.LostFocus += new EventHandler(this.FocusOver);
innerTextBox.Hide();
innerTextBox.Text = "";
在 DoubleClick 事件上绑定自己的方法，在其中查找选定的项目并将值获取到 TextBox
this.DoubleClick += new EventHandler(this.EditableDoubleClick);
private void EditableDoubleClick（对象发送者，System.EventArgs e）
{
selectedItemText = selectedItem.ToString();
innerTextBox.Size = new Size(subItemRect.right - subItemRect.left, subItemRect.bottom - subItemRect.top);
innerTextBox.Location = new Point(subItemRect.left, subItemRect.top);
innerTextBox.Show();
innerTextBox.Text = selectedItemText;
}
当文本框中失去焦点时 - 将值设置回所选项目。
selectedItem = insideTextBox.Text;
I'm using some similar for ListView. Method is:
Create TextBox, add to Controls array, and hide one.
innerTextBox.Size = new Size(0, 0);
innerTextBox.Location = new Point(0, 0);
this.Controls.AddRange(new Control[] { this.innerTextBox });
innerTextBox.KeyPress += new KeyPressEventHandler(this.EditOver);
innerTextBox.LostFocus += new EventHandler(this.FocusOver);
innerTextBox.Hide();
innerTextBox.Text = "";
On DoubleClick event bind own method where find selected Item and get value to TextBox
this.DoubleClick += new EventHandler(this.EditableDoubleClick);
private void EditableDoubleClick(object sender, System.EventArgs e)
{
selectedItemText = selectedItem.ToString();
innerTextBox.Size = new Size(subItemRect.right - subItemRect.left, subItemRect.bottom - subItemRect.top);
innerTextBox.Location = new Point(subItemRect.left, subItemRect.top);
innerTextBox.Show();
innerTextBox.Text = selectedItemText;
}
On lost focus in TextBox - set value back into selected item.
selectedItem = innerTextBox.Text;
