        <syncfusion:DataGridNumericColumn MappingName="EmployeeID"
                                          Format="#"
                                          HeaderText="Employee ID"
                                          AllowNullValue="True" />
        <syncfusion:DataGridTextColumn MappingName="Name"
                                       HeaderText="Employee Name" />
        <syncfusion:DataGridTextColumn MappingName="Title"
                                       HeaderText="Designation" />
        <syncfusion:DataGridDateColumn MappingName="HireDate"
                                       HeaderText="Hire Date" />
