Conditional Where clause in LINQ

Question

suppose i am showing data in grid and i have many textboxes for filter the data. textbox for employee id. if employee id textbox is empty then no where clause will be added

Answer 1

Try this:-

First select the data:-

var r = from t in TblFamilie
select new
{
    t.ID,
    t.ParentID,
    t.Name,
    t.CurDate
};

Then you can filter based on condition:-

   if (sName!="")
        r = r.Where(x => x.Name == sName);
