<dataGrid:SfDataGrid  x:Name="dataGrid"
                    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"
                                    DisplayBinding="{Binding Path=Salary,Converter={StaticResource currencyFormatConverter}}"/>

</dataGrid:SfDataGrid>

C#

public MainPage()

    //Equivalent to the code in the XAMl section

    DataGridTextColumn salaryColumn = new DataGridTextColumn() { MappingName = "Salary", HeaderText = "Salary" };
    salaryColumn.DisplayBinding = new Binding() { Path = "Salary", Converter = new CurrencyFormatConverter() };
    dataGrid.Columns.Add(salaryColumn);
