Wpf:datagrid automatically generate line numbers

Let's share a way to automatically generate row numbers for DataGrid data by Datagridrowheader. It takes only one valueconverter to get it done.

1. Value Converters

   1     classAutonumbervalueconverter:imultivalueconverter2     {3         #regionImultivalueconverter Members4 5          Public ObjectConvert (Object[] values, Type targetType,Objectparameter, System.Globalization.CultureInfo culture)6         {7             varitem = values[0];8             varItems = values[1] asitemcollection;9 Ten             varindex =items. IndexOf (item); One             return(Index +1). ToString (); A         } -  -          Public Object[] Convertback (ObjectValue, type[] targettypes,Objectparameter, System.Globalization.CultureInfo culture) the         { -             return NULL; -         } -  +         #endregion -}

2. Front Code

   1<window x:class="Datagridautorownumberdemo.mainwindow"2xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"3xmlns:x="Http://schemas.microsoft.com/winfx/2006/xaml"4xmlns:demo="Clr-namespace:datagridautorownumberdemo"5title="MainWindow"6Width="525"7height=" -">8<Window.Resources>9<demo:autonumbervalueconverter x:key="Autonumbervalueconverter"/>Ten</Window.Resources> One<datagrid x:name="DataGrid"> A<DataGrid.RowHeaderStyle> -<style targettype="{x:type Datagridrowheader}"> -<setter property="Content"> the<Setter.Value> -<multibinding converter="{StaticResource Autonumbervalueconverter}"> -<binding/> -<binding path="Items"Relativesource="{RelativeSource Ancestortype={x:type DataGrid}}"/> +</MultiBinding> -</Setter.Value> +</Setter> A</Style> at</DataGrid.RowHeaderStyle> -</DataGrid> -</Window>

   Get it done!
