"DataBinding: 'Sherserve.CustomTypeLayer.EmployeeLeave' does not contain a property with the name 'empId' "

here is my code :

protected void Button1_Click(object sender, EventArgs e)
{
    LMSManager leavestatus = new LMSManager();
    int emplid = Convert.ToInt32(Session["EmployeeID"]);
    List<EmployeeLeave> leaverecord = leavestatus.GetLeaveRecord(emplid);

Your question can't be answered as you haven't shown us `EmployeeLeave` or the data binding... — Daniel Hilgarth, Aug 31 '12 at 10:37
I assume that this is ASP.NET, show us the aspx markup of the grid as well. — Tim Schmelter, Aug 31 '12 at 10:37
What about your [previous question](http://stackoverflow.com/questions/12209819/int-does-not-contain-a-definition-and-no-extension-method/12209850#12209850) its the same problem, you should resolve it first rather than asking question without complete information — Habib, Aug 31 '12 at 10:38
You are missing a basic thing, you need to get an object of `EmployeeLeave` `with emplid` in your method `GetLeaveRecord` — Habib, Aug 31 '12 at 10:41

It looks like your databinding is referring to empId while the field on EmployeeLeave is actually called EmployeeId.

Try changing

<ItemTemplate>
    <asp:Label ID="lblEmpId" runat="server" Text='<%#Eval("empId")%>'></asp:Label>
</ItemTemplate>

to

<ItemTemplate>
    <asp:Label ID="lblEmpId" runat="server" Text='<%#Eval("EmployeeId")%>'></asp:Label>
</ItemTemplate>

No i am getting empid from session. – Ammar Asjad Aug 31 '12 at 10:43
Each row on the `DataGrid` binds to an instance of `EmployeeLeave`, which does not have the `empId` property. Are you trying to bind to the `int emplid = Convert.ToInt32(Session["EmployeeID"]);` value from your first code block? – Pieter Müller Aug 31 '12 at 10:53
