问题描述
我编写此代码来设置数据列表项目的背景色
i write this code for setting backcolor of datalist items
protected void dlTrades_ItemDataBound(object sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
System.Data.DataRowView drv = (System.Data.DataRowView)(e.Item.DataItem);
string hld = (string)drv.Row["Color"].ToString();
if (hld == "RED")
{
e.Item.BackColor = System.Drawing.Color.Red;
}
但是在dlTrades_itemCommand事件上，项目的背景颜色消失了...我如何在itemcommand事件上保留这些颜色?

推荐答案
将断点放在itemdatabound事件上，然后在dlTrades_itemCommand事件完成后尝试触发itemcommand事件检查，您的代码是否再次进入dlTrades_ItemDataBound. .
如果没有到达那里，那么要获得背景色，您必须在dlTrades_itemCommand事件完成后重新整理列表
试试看，我认为在调试代码后，您会发现您的代码在哪里很弱，无法重新绑定背景色..
put the breake point on itemdatabound event and then try to fire itemcommand event check after completion of your dlTrades_itemCommand event your code again goes to dlTrades_ItemDataBound this or not..
if it is not going to there then for getting a back color you have to refreace your list after your dlTrades_itemCommand event is complete
try this it will i think after you debug your code you will find that where is your code is weak to rebind the back color..
