أرجو حذف الفراغات من سلسلة الاتصال بقاعدة البيانات

string sql = "datasource= localhost; port=3306;username=root;password=;database=employeedb";

لتصبح:

string sql = "datasource=localhost;port=3306;username=root;password=;database=employeedb";
                        ^^^^

وانتبه لفصل الكلمات المفتاحية

DbEmployee.DisplayAndSearch("SELECT* From employee_table", dataGridView);
=>
DbEmployee.DisplayAndSearch("SELECT * From employee_table", dataGridView);
                                ^^^^^^

كما تأكد من الشروط على بنية الجدول، هل تقبل NULL ؟؟

string sql = "INSERT INTO employee_table

VALUES(NULL,@EmpName,@RegNo,@Job_Tile,@Position,@Hiring_Date,@Country,@Birthdate,@Gender,@Phone,@Address,@Photo,@Dept
      ^^^^^^^

Id,NULL)";
 ^^^^^^^^^

في حال غير ذلك قم بتحديد أسماء الأعمدة التي تريد إضافة بيانات لها لكل منهم ثم نمرر VALUES

قمت بتحديد null لخانة id بحكم انها ستكون متغيرة لكل موظف مدخل ولن تتكرر

حددها ك auto increment ولا تقم بتمرريها ضمن الاستعلام
