推荐答案

您可以用数据键和的ItemDataBound 事件做到这一点。

You can do this with data keys and the ItemDataBound event.

<asp:ListView ID="ListView1" runat="server" DataKeyNames="UserID" OnItemDataBound="ListView1_ItemDataBound" ... />

在除了上述，您还需要在服务器控件包每个项目，所以你可以调整背景色：

In addition to the above, you'll also need to wrap each item in a server control so you can adjust the background color:

<ItemTemplate>
    <asp:Panel ID="Panel1" runat="server">
        <!-- the item content here -->
    </asp:Panel>
</ItemTemplate>

下面是一些例子code-背后：

Here's some example code-behind:

protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
{
    var dataItem = e.Item as ListViewDataItem;
    if (dataItem != null)
    {                        
        var innerPanel = dataItem.FindControl("Panel1") as Panel;
        if (innerPanel!= null)
        {
            var userID = (int)ListView1.DataKeys[dataItem.DisplayIndex]["UserID"];
            if (userID == base.User.UserID)
                innerPanel.BackColor = Color.PeachPuff;
        }
    }        
}
