I am trying to move listbox items between two listboxes.Before that i created two arrraylists for each listbox.so before moving the listbox item i am trying to add the items to the arraylist. here is the code
foreach (string st in listbox1.Items)
{
arraylist1.Add(st1);
}
but i am getting an exeption Unable to cast object of type 'System.Web.UI.WebControls.ListItem' to type 'System.String'.
You're getting this error because listbox1.Items
is a ListItemCollection.
foreach (ListItem li in listbox1.Items)
{
arraylist1.Add(li.Text);
}
foreach (string st in listbox1.Items)
should be
foreach (ListItem st in listbox1.Items)
// your code
Try using
foreach (ListItem li in listbox1.Items)
{
arraylist1.Add(li.Text);
}
ListBox.Items is of ListItemCollection type. It consists of ListItem objects, not strings.
What You are trying to do is:
foreach (ListItem lstItem in ListBox1.Items)
{
arraylist1.Add(lstItem);
}
This is because a list item is an object in it's own right and not a string object. So change the string to ListItem in your code above and it should work fine.
