you can use this code :

var query = from d in datacontext.sample where   
                            (TBoxFName.Text=="" || d.FirstName.Contains(TBoxFName.Text.Trim()))
                            &&(TBoxLName.Text == "" || d.LastName.Contains(TBoxLName.Text.Trim()))
                            &&(TBoxFatherName.Text == "" || d.FatherName.Contains(TBoxFatherName.Text.Trim()))
                            && (TBoxPriceDebt.Text == "" || d.DebtPrice.ToString().Contains(TBoxPriceDebt.Text.Trim()))
                            && (CBoxBranch.Text == "" || d.BranchName.Contains(CBoxBranch.Text.Trim()))
                            &&(TBoxDebt.Text == "" || d.DebtId.Contains(TBoxDebt.Text.Trim()))
                            &&(TBoxMeliCode.Text == "" || d.MeliCode.Contains(TBoxMeliCode.Text.Trim()))
                                select d;
