Two questions about list view??

[rahmanjan]

Hi all,

I am populating my list view with some dummy text with checkboxes on.

My questions are:

1-I am trying get the text and index for the items that have been Checked.

int totalItems=listView1.Items.Count-1;

for (int n=0;n<totalItems;n++)
{
if (listView1.CheckedItems[n].Checked==true)
{
MessageBox.Show(&quot;Selected Item Text: &quot; + listView1.Items[n].Text);
MessageBox.Show(&quot;Selected Item Index: &quot; + listView1.Items[n].Index);
}
}

I do as above. But It dispalys even un checked rows. I dont' know why???

2- How can i get only one checked row? If multiple selection is false?

regards

First, you have a little mistake. If you write this:
int totalItems=listView1.Items.Count-1;
then in the loop you have to write:
n<=totalItems
but, it is very important to use a variable as the meaning of it, so totalItems holds the number of items that it is the count itself, so write:
int totalItems=listView1.Items.Count;
and leave the loop as it is.
Second, there is a better way to do what you did.
If you want to discover the selected items use:
listView1.SelectedItems.Count
and
listView1.SelectedItems[n] to get the item.
You can do the same for checked items:
listView1.CheckedItems.Count
and
listView1.CheckedItems[n] to get the item.
This list contains only the items that are checked only if you set the property CheckBoxes in the list properties to True, as it is written in:
