Question

I have a DataGrid to insert data into Sql Server table. Inside of DataGrid I have ComboBox to pick the data from a codebook (this is the table from the same database) and insert this data into table I bound to DataGrid. This is the XAML:

<DataGrid Name="dgrStavke" AutoGenerateColumns="False" Height="160" Width="600" HorizontalAlignment="Left" Margin="5" Grid.Row="7" Grid.ColumnSpan="4">
        <DataGrid.Columns>
            <DataGridTemplateColumn Header="Artikl ID">
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <ComboBox Name="cmbArticle" Width="120" ></ComboBox>
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>                    
            </DataGridTemplateColumn>
            <DataGridTextColumn Header="Article Name" Width="150"></DataGridTextColumn>
            <DataGridTemplateColumn Header="Usluga ID">
                <DataGridTemplateColumn.CellEditingTemplate>
                    <DataTemplate>
                        <ComboBox Name="cmbService" Width="120"></ComboBox>
                    </DataTemplate>
                </DataGridTemplateColumn.CellEditingTemplate>
            </DataGridTemplateColumn>
            <DataGridTextColumn Header="Service Name" Width="150"></DataGridTextColumn>
        </DataGrid.Columns>
    </DataGrid>

When I choose article id in combobox article, the very next DataGridTextColumn should display name of this article. The same is for service. It’s possible to insert few articles and services and that’s the reason I use Datagrid.

How can I do this?

Thanks.

I guess the below sample would help you to achieve your goal

In XAML below code used,

<Window.Resources>
        <ObjectDataProvider x:Key="RecordValues" ObjectType="{x:Type local:RecordTemp}" MethodName="GetPersonList" >            
        </ObjectDataProvider>
    </Window.Resources>
    <Grid>
        <Grid>
            <DataGrid AutoGenerateColumns="False" ItemsSource="{Binding}"
                  Margin="10,10,73,155" Name="dataGrid1">
                <DataGrid.Columns>
                    <DataGridComboBoxColumn Header="Artikl ID" Width="300" 
                                            SelectedValueBinding="{Binding SelectedPart, UpdateSourceTrigger=PropertyChanged}"                                            
                                            DisplayMemberPath="ArticleID"
                     ItemsSource="{Binding Source={StaticResource RecordValues}}" />

                    <DataGridTextColumn Header="Order Name" Binding="{Binding SelectedPart.ArticleName}" />
                </DataGrid.Columns>
            </DataGrid>            
        </Grid>
    </Grid>

In C# below code used,

public class RecordTemp : INotifyPropertyChanged
{
    List<PartsList> _value = new List<PartsList>();

   public RecordTemp()
    {
        _value.Add(new PartsList() { ArticleID = "1", ArticleName = "one - 1", ArticleQuantity = 20 });
        _value.Add(new PartsList() { ArticleID = "2", ArticleName = "Two - 2", ArticleQuantity = 10 });
    }

    public List<PartsList> GetPersonList()
    {
        return _value;
    }

    private PartsList _SelectedPart;

    public PartsList SelectedPart
    {
        get { return _SelectedPart; }
        set
        {
            _SelectedPart = value;
             OnPropertyChanged("SelectedPart");
        }
    }

    public void OnPropertyChanged(string propertyName)
    {
        if (PropertyChanged != null  )
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    }     


    #region INotifyPropertyChanged Members

    public event PropertyChangedEventHandler PropertyChanged;



    #endregion
}

 public class PartsList
{
    public string ArticleID { get; set; }
    public double ArticleQuantity { get; set; }
    public string ArticleName { get; set; }
    }

In the MainWindow the below code could helps to binding the grid.

ObservableCollection<RecordTemp> RecordsTemp = new ObservableCollection<RecordTemp>();
RecordsTemp.Add(new RecordTemp());
RecordsTemp.Add(new RecordTemp());
dataGrid1.DataContext = RecordsTemp;
