GetAllEmployee() returns List, it is working" - Are you sure?
It looks like ObjEmployee stores single employee data, not a list of employees.
Provide class declaration and implementation - use "Improve question" widget.

Solution 1

To search for a single employee data you should change you code like in the next example:

C#

Employee ObjEmployee = dataContext.Employees.FirstOrDefault(emp => emp.EmployeeCode == txtempcode.Text);

Where dataContext is your data context object, an object of type of your "Data Context Class" derived from ObjectContext.
