更改属性网格中的显示名称
Changing the display names in a propertygrid
我正在创建测试 class 的列表<>，我创建了。然后我将它转换为数组并将其分配给 propertygrid 控件。
List<Test> lc_Test;
public class Test : UserControl
{
[Category("lc_Test"), Description("Testing using List<>, for storage."), DisplayName("Images")]
public Image img { get; set; }
}
// Above in Form1(), I create it
// lc_Test = new List<Test>();
private void button7_Click(object sender, EventArgs e)
{
lc_Test.Clear();
lc_Test.Add(new Test());
lc_Test.Add(new Test());
lc_Test[0].img = pb1.Image;
lc_Test[1].img = pb2.Image;
MessageBox.Show(lc_Test.Count.ToString());
pgTest.SelectedObject = lc_Test.ToArray();
}
如图所示，有效：
我现在想知道，是否有任何方法可以更改每个项目的显示名称。因为，它将它们命名为“(0)”和“(1)”。在这个测试中，我想把它改成说。 "Test Item 0" 和 "Test Item 1"。我还需要更改每个项目的 "Help Text"。一定要有办法。
任何人，需要我告诉我什么。
