请帮我解决一下这个。
private void Cells_CheckedListBox_SelectedIndexChanged(object sender, EventArgs e)
{
if (Cells_CheckedListBox.GetItemChecked(Cells_CheckedListBox.Items.IndexOf("All Cells")))
{
for (int i = 0; i < Cells_CheckedListBox.Items.Count; i++)
{
Cells_CheckedListBox.SetItemCheckState(i, CheckState.Checked);
}
}
}
You seem to be doing this in the wrong event altogether. 您似乎完全是在错误的事件中执行此操作。 You should handle the
ItemCheck
event. 您应该处理
ItemCheck
事件。
private void Cells_CheckedListBox_ItemCheck(object sender, ItemCheckEventArgs e)
{
int allIndex = Cells_CheckedListBox.Items.IndexOf("All Cells");
if (e.Index == allIndex)
{
for (int i = 0; i < Cells_CheckedListBox.Items.Count; i++)
{
if (i != allIndex)
Cells_CheckedListBox.SetItemCheckState(i, e.NewValue);
}
}
}
