Hi, everyone:

Is there some way to know all of the index number of all
selected item in a multi-selection list web control.

Sincerely,

Hi haiwen,

You need to iterate through the ListItemCollection collection, exposed by
the Items property and check the Selected property for each ListItem.

hi, thanks for your reply, but it seems we can get all of the indexs by
the SelectedIndices[] of the listbox. for web form, even I iterate
through the listitem collection and get the selected item by checking
its selected property. this selected item doesn't have index property. I
can't find the way to get the index of these items even I know they are
selected on Web Form. could you give me some code.

Thank you so much

Hi, Thank you for your reply,
But even after I iterate through the ListItem and get all
the selected items, it seems the item doesn't have any
property to know its index at the ListBox on Web Form. on
Window Form, we can get them by SelectedIndices[].

Could you give me some code to show how to do it.

Sincerely,

haiwen
