Remove whole ListViewItems except first Column
I want to remove whole ListviewItems in my Listview e开发者_运维知识库xcept first Column. I have got a method but it sometimes throw ArgumentRangeException that i could not find why.
private void ListViewClear()
{
for (int i = 0; i < lstKullanicilar.Items.Count; i++)
{
if (lstKullanicilar.Items[i].SubItems.Count != 1)
{
lstKullanicilar.Items[i].SubItems.RemoveAt(1);
lstKullanicilar.Items[i].SubItems.RemoveAt(2);
lstKullanicilar.Items[i].SubItems.RemoveAt(3);
lstKullanicilar.Items[i].SubItems.RemoveAt(1);
lstKullanicilar.Items[i].SubItems.RemoveAt(1);
}
}
Try somethin like this:
for (int i = 0; i < lstKullanicilar.Items.Count; i++) {
while(lstKullanicilar.Items[i].Count > 1){
lstKullanicilar.Items[i].SubItems.RemoveAt(1);
}
}
The problem with your code is probably that you have a variable amount of items in the SubItems-collection. WIth the code you showed, you must at least have 6 items in the subitems-collection, for not getting an arugment exception.
