WPF DataGrid Binding ComboBox

WPF DataGrid binding ComboBox

One of the columns in the DataGrid in WPF is the ComboBox solves this problem for a lot of time, no nonsense about directly on the code

XAML Code

<datagridtemplatecolumn header= "group name" >

<DataGridTemplateColumn.CellTempLate>

<DataTemplate>

<combobox selectedvalue= "{Binding path=name}" itemsource={binding Path=selectionlist,relativesource

={relativesource Ancestortype={x:type usercontrol},mode=findancestor}}></combobox>

<DataTemplate>

<DataGridTemplateColumn.CellTempLate>

</datagridtemplatecolumn >

Xmal's code is finished. The following code is written in the background.

The. CS code is as follows:

Public observablecollection<string> SelectionList//observablecollection This is a class that needs to be referenced (using System.Collections.ObjectModel)

{

Get{return _selectionlist;}

Set{_selectionlist=value;}

}

Private observablecollection<string> _selectionlist=new observablecollection<string> (); This is an important step in the realization.

Why use ObservableCollection class, can search on the Internet by oneself

The next step should be to add a value to SelectionList.

SelectionList. ADD ("Name1");

SelectionList. ADD ("Name2");

So the ComboBox down the box has Name1 and Name2, of course SelectionList can also add background query Datatabel value, nothing but add a loop just

This is the value to add a value to the ComboBox, the last step, the value from the database to bind to the ComboBox, so that the default display

(select Name, field ... from table) query a collection of DataTable

The name of the DataGrid (its own name) Datagrid.itemsource=datatable.defaultview;

The queried name will be bound to the ComboBox.
