从列表或数据集中设置checkedlistbox中的选中项 [英] Set checked items in checkedlistbox from list or dataset

问题描述

我有一个 CheckedListBox，我想检查另一个列表中的所有项目.此代码不起作用，因为 CheckedItems 属性是只读的并且类型不匹配，但它给出了我想要做的最好的想法.

I have a CheckedListBox and I would like to check all the items that are in another List. This code does not work since the CheckedItems property is read-only and the types do not match, but it gives the best idea of what I want to do.

    checkedListBox1.DataSource = DataSetSelectAll().Tables[0];
    checkedListBox1.ValueMember = "id_table";
    checkedListBox1.DisplayMember = "name";

    List<tableClass> list = MyCheckedList();
    checkedListBox1.CheckedItems = list;

我知道这是错误的，但不知道如何更好地解释它.

I know this is wrong but do not know how to explain it better.

推荐答案

这样一次设置(检查)多个项目是不可能的，checkedListBox1.CheckedItems = list;

Its not possible to set(check) many items at a time like this, checkedListBox1.CheckedItems = list;

你可以更好地使用 for 循环，例如:

better you can use for loop like:

List<tableClass> list = MyCheckedList();
for (int count = 0; count < checkedListBox1.Items.Count; count++)
{
  if (list.Contains(checkedListBox1.Items[count].ToString()))
  {
    checkedListBox1.SetItemChecked(count, true);
  }
}
