ItemDataBound
帮我看看那里错了
if(e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
{
((LinkButton)(e.Item.Cells[7].Controls[0])).Attributes.Add( "onclick ", "return confirm( '确认删除吗？ ') ");
lbl = (Label)e.Item.FindControl( "lbl ");
DataRowView drv =(DataRowView)e.Item.DataItem;
date1 = (DateTime)drv[ "jiezhitime "]; //取出数据库中的时间
if(date1> DateTime.Now)
{
this.lbl.Text=drv[ "jiezhitime "].ToString();
}
else
{
this.lbl.Text= "过期 ";
}
}
提示：
this.lbl.Text=drv[ "jiezhitime "].ToString();未将对象引用设置到对象的实例。
[解决办法]
private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if(e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
{
((LinkButton)(e.Item.Cells[7].Controls[0])).Attributes.Add( "onclick ", "return confirm( '确认删除吗？ ') ");
Label lbl = (Label)e.Item.FindControl( "lbl "); //你的肯定有这个lbl哦
DataRowView drv =(DataRowView)e.Item.DataItem;
date1 = (DateTime)drv[ "jiezhitime "]; //取出数据库中的时间
if(date1> DateTime.Now)
{
this.lbl.Text=drv[ "jiezhitime "].ToString();
}
else
{
this.lbl.Text= "过期 ";
}
}
}
[解决办法]
this.lbl ==> lbl另要注意控件存在.
