关于从ListPageObj传递值以显示标签上的值,我遇到了问题。 我怎样才能获得价值?
BLL
public List<ListPageObj> MyList(int ItemID)
{
return (from a in ctx.Item where a.ItemID == ItemIDselect new ListPageObj
{
Item1= a.Item1,
Item2= a.Item2,
Item3= a.Item3
}).ToList<ListPageObj>();
}
ListPageObj
public string Item1
{ get; set; }
public string Item2
{ get; set; }
public string Item3
{ get; set; }
ASPX
<asp:label id="label1" runat="server" />
<asp:label id="label2" runat="server" />
<asp:label id="label3" runat="server" />
aspx.cs?
//code to retrieve item1, item2, item3 value from BLL
label1.Text = ListPageObj.Item1; // gives me null value
label2.Text = ListPageObj.Item2; // gives me null value
label3.Text = ListPageObj.Item3; // gives me null value
答案 0 :(得分:0)
aspx.cs页面
ListPageObj ObjItem = ClassName.MyList(ItemID);
label1.Text = ObjItem.Item1;
label2.Text = ObjItem.Item2;
label3.Text = ObjItem.Item3;
BLL
public ListPageObj MyList(int ItemID)
{
return (from a in ctx.Item where a.ItemID == ItemIDselect new ListPageObj
{
Item1= a.Item1,
Item2= a.Item2,
Item3= a.Item3
}).FirstOrDefault();
}
