                    ColumnWidthMode="Auto" 
                    GridLinesVisibility="Both" 
                    HeaderGridLinesVisibility="Both"
                    ItemsSource="{Binding Employees}">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:DataGridNumericColumn MappingName="EmployeeID" HeaderText="Employee ID"/>
        <dataGrid:DataGridTextColumn MappingName="Name" />
        <dataGrid:DataGridNumericColumn MappingName="Salary" 
                                    HeaderText="Salary"
