我的code:

int listcount = ListView.Items.Count;

我的aspx:
<div class="InputControlBox">
<asp:ListView ID="ListView" runat="server" OnItemCommand="ListView_ItemCommand"
OnSelectedIndexChanging="ListView_SelectedIndexChanging" OnItemDeleting="ListView_Deleting">
<LayoutTemplate>
...
</LayoutTemplate>
<ItemTemplate>
...
</ItemTemplate>
</asp:ListView>
</div>
哪里错误?
推荐答案
侑可以使用code
if (e.CommandName == "Delete")
{
int index = Convert.ToInt32(e.CommandArgument);
int listcount = ListView.Items.Count;
if (listcount - 1 == index)
{
dataTable.Rows[index].Delete();
ListView.datasource = datatable;
ListView.DataBind();
}
}
其中dataTable的是你绑定到ListView的数据源。
where dataTable is the datasource where you bind to your ListView.
