To remove or delete multiple selected items from a ListBox in ASP.NET on button click, you can use the `SelectedIndexChanged` event of the Button control and iterate through the selected items of the ListBox to remove them.nnHere's an example:nn```html
<asp:ListBox ID="lstData" runat="server" ... />
<asp:Button ID="btnRemoveSelected" runat="server" OnClick="btnRemoveSelected_Click" Text="Remove Selected Items" />
<script>nfunction btnRemoveSelected_Click(sender, args) {n var selectedItems = lstData.get_selecteditems();n for (var i = 0; i < selectedItems.length; i++) {n lstData.items.removeAt(lstData.items.indexOf(selectedItems[i]));n }n}n</script>
```
