如何在ListView C#中同时实现复选框和选择 [英] How do I achieve both check box and selection simultaneously in listview C#

问题描述

无论何时选中此复选框，都应选择相应的项目，反之亦然

我尝试过的事情:

Itemchecked事件我只是将选定的属性分配给选中的项目
示例:

Whenever the checkbox is checked the corresponding item should be selected and vice versa

What I have tried:

Itemchecked event i just assign the selected property to the checked item
Example :

private void listview_ItemChecked(object sender, ItemcheckedEventArgs e) 
{
   e. item. Selected = e. item. Checked;
}

推荐答案

列表listBox2_selectionhistory = new List();

私有无效checkedListBox2_SelectedIndexChanged(对象发送者，EventArgs e)
{
int actualcount = listBox2_selectionhistory.Count;
如果(实际计数== 1)
{
如果(Control.ModifierKeys == Keys.Shift)
{
int lastindex = listBox2_selectionhistory [0];
int currentindex = CheckedListBox2.SelectedIndex;
int upper = Math.Max(lastindex，currentindex);
int lower = Math.Min(lastindex，currentindex);
for(int i = lower; i< upper; i ++)
{
CheckedListBox2.SetItemCheckState(i，CheckState.Checked);
}
}
listBox2_selectionhistory.Clear();
listBox2_selectionhistory.Add(checkedListBox2.SelectedIndex);
}
其他
{
listBox2_selectionhistory.Clear();
listBox2_selectionhistory.Add(checkedListBox2.SelectedIndex);
}
}
我想这应该对你有帮助

List listBox2_selectionhistory = new List();

private void checkedListBox2_SelectedIndexChanged(object sender, EventArgs e)
{
int actualcount = listBox2_selectionhistory.Count;
if (actualcount == 1)
{
if (Control.ModifierKeys == Keys.Shift)
{
int lastindex = listBox2_selectionhistory[0];
int currentindex = checkedListBox2.SelectedIndex;
int upper = Math.Max(lastindex, currentindex) ;
int lower = Math.Min(lastindex, currentindex);
for (int i = lower; i < upper; i++)
{
checkedListBox2.SetItemCheckState(i, CheckState.Checked);
}
}
listBox2_selectionhistory.Clear();
listBox2_selectionhistory.Add(checkedListBox2.SelectedIndex);
}
else
{
listBox2_selectionhistory.Clear();
listBox2_selectionhistory.Add(checkedListBox2.SelectedIndex);
}
}
