Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public void Remove(
	ListItem item
)

Parameters

item
Type: System.Web.UI.WebControls.ListItem

The ListItem to remove from the collection.

Use the Remove method to remove a ListItem from the collection. This implementation of the method takes the ListItem specified by the item parameter and removes it from the collection.

The following code example demonstrates creating ListItemCollection objects, adding items to the collections, and removing items from the collections. In the example, the ListItemCollection named listBoxData is used as the data source for a ListBox control called ListBox1, and the ListItemCollection called ddBoxData is used as the data source for a DropDownList control called DropDownList1. To view this code in a fully working example, see the WebControl class topic.

//Set the SelectedIndex to -1 so no items are selected.
// The new item will be set as the selected item when it is added.
DropDownList1.SelectedIndex = -1;
// Add the selected item to DropDownList1.
DropDownList1.Items.Add(ListBox1.SelectedItem);
// Delete the selected item from ListBox1.
ListBox1.Items.Remove(ListBox1.SelectedItem);
