复选框在您勾选项目时显示选择的项目

问题描述

使用winform，
我要使用哪个事件来确保在我选中已选中列表框内的项目时，在文本框中填充了这些值?

我正在使用selectedindexchanged，但是它不能正常工作.
例如，我在两个项目旁边打勾，该文本框仅显示第一个项目.
要在文本框中获得第二个被打勾的项目，我必须在复选框中单击另一个项目.

有什么想法吗?
谢谢

using winform,
Which event do I use to make sure that as I am ticking items inside a checked listbox, a textbox is populated with those values?

I am using the selectedindexchanged but it does not work accurately.
For example, I put a tick next to two items, The textbox shows only the first item.
To also get the second ticked item in th etextbox, I have to click on another item in the checklistbox.

Any thoughts please?
Thanks

推荐答案

private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e) {
  CheckedListBox clb = (CheckedListBox)sender;
  if (e.NewValue == CheckState.Checked) {
    textBox1.AppendText(String.Format(Environment.NewLine + "Checking {0}", clb.Items[e.Index]));
  } else {
    textBox1.AppendText(String.Format(Environment.NewLine + "Unchecking {0}", clb.Items[e.Index]));
  }
}
