A simple way to bind the ComboBox of a DataGrid in WPF (Absolutely simple)

Before writing the text, I have to say that the other WPF on the web to bind the way the ComboBox, after watching really let people want to die.

Let's start by telling you a whole bunch of models, a bunch of control templates, and maybe you just want to know how to make the ComboBox show up.

Convention First:

To achieve this effect is very simple, except to let the data model tightly only a few lines of code.

Look at the data model first:

View Sourceprint? 01. public  class  VModel : INotifyPropertyChanged 02. { 03. private  string _Name; 04.  05. public  string Name 06. { 07. get {  return  _Name; } 08. set 09. { 10. if  (_Name != value) 11. _Name = value; 12. OnPropertyChanged( "Name" ); 13. } 14. } 15.  16. private  List<string> _Desciption; 17.  18. public  List<string> Desciption 19. { 20. get {  return  _Desciption; } 21. set { 22. if  (_Desciption != value) 23. _Desciption = value; 24. OnPropertyChanged( "Desciption" ); 25. } 26. } 27.  28. public  event PropertyChangedEventHandler PropertyChanged; 29.  30. protected  void  OnPropertyChanged(string propertyName) 31. { 32. if  (string.IsNullOrEmpty(propertyName))  throw  new  ArgumentNullException( "propertyName" ); 33. PropertyChangedEventHandler handler = PropertyChanged; 34. if  (handler !=  null ) handler( this ,  new  PropertyChangedEventArgs(propertyName)); 35. } 36.  37. }

The onpropertychanged in the back does not need to be cared for in order to achieve dynamic data changes, generally not required

Look at the template for the ComboBox in the DataGrid that's the point.

View Sourceprint? 01. <DataGrid AutoGenerateColumns= "False"  Height= "236"  HorizontalAlignment= "Left"  Margin= "12,0,0,0"  Name= "dataGrid1" VerticalAlignment= "Top"  Width= "471" > 02. <DataGrid.Columns> 03. <DataGridTextColumn Header= "Header1"  Binding= "{Binding Name}"  /> 04. <DataGridTemplateColumn Header= "Template" > 05. <DataGridTemplateColumn.CellTemplate> 06. <DataTemplate> 07. <ComboBox ItemsSource= "{Binding Desciption}"  /> 08. </DataTemplate> 09. </DataGridTemplateColumn.CellTemplate> 10. </DataGridTemplateColumn> 11. </DataGrid.Columns> 12. </DataGrid>

You see that? Total two columns A TextBox a ComboBox is simply a few lines apart from the data model can be done!

Initialization of the data:

View Sourceprint? 01. List<VModel> vs =  new  List<VModel>(); 02. VModel v1 =  new  VModel(); 03. v1.Name =  "Sean" ; 04. v1.Desciption =  new  List<string>(); 05. v1.Desciption.Add( "1" ); 06. v1.Desciption.Add( "2" ); 07. v1.Desciption.Add( "3" ); 08. vs.Add(v1); 09. dataGrid1.ItemsSource = vs;also attachedTo add a static entity to a resource and then reference the resource when binding, two steps are done:

Public observablecollection<department> Listdepartments{set;get;}

Listdepartments = DB. Getcollection<department> ();

This. DataContext = this;

<Window.Resources>

<collectionviewsource x:key= "departments" source= "{Binding listdepartments}"/>

</Window.Resources>

<datagridcomboboxcolumn width= "header=" professional group selectedvaluepath= "Name" textbinding= "{Binding Department}" Itemssource= "{Binding source={staticresource Departments}}" Displaymemberpath= "Name"/>
