I have this code behind : 

```
private void InitializeListView()
    {
        //RAZ
        lv.Items.Clear();

        GridView gridView = new GridView();
        gridView.AllowsColumnReorder = true;

        GridViewColumn gvc1 = new GridViewColumn();
        gvc1.DisplayMemberBinding = new System.Windows.Data.Binding("SN");
        gvc1.Header = "SN";

        GridViewColumn gvc2 = new GridViewColumn();
        gvc2.DisplayMemberBinding = new System.Windows.Data.Binding("a1");
        gvc2.Header = "A1";
        gridView.Columns.Add(gvc2);

        GridViewColumn gvc3 = new GridViewColumn();
        gvc3.DisplayMemberBinding = new System.Windows.Data.Binding("a2");
        gvc3.Header = "A2";
        gridView.Columns.Add(gvc3);

        for (int i = 0; i < lv.Count; i++)
        {
            this.lv.Items.Add(
                new dataToUse
                {
                    sn= tab[i][0],
                    a1= tab[i][1],
                    a2 = tab[i][2]
                });
        }

        this.lv.View = gridView;
    }

```

in order to generate dinamycally this :

```
<ListView  x:Name="lv" HorizontalAlignment="Left" Height="360" Margin="305,192,0,0" VerticalAlignment="Top" Width="607" SelectionMode="Extended"  >

        <ListView.View >
            <GridView  AllowsColumnReorder="true">
                <GridViewColumn DisplayMemberBinding="{Binding sn}" >
                    <GridViewColumnHeader>
                        <GridViewColumnHeader.ContextMenu>
                            <ContextMenu>
                                <MenuItem Header="Asc"/>
                                <MenuItem Header="Desc" />
                            </ContextMenu>
                        </GridViewColumnHeader.ContextMenu>
                    </GridViewColumnHeader>
                </GridViewColumn>

                <GridViewColumn DisplayMemberBinding="{Binding a1}">
                    <GridViewColumnHeader >
                        <GridViewColumnHeader.ContextMenu>
                            <ContextMenu >
                                <MenuItem Header="Asc"  />
                                <MenuItem Header="Desc" />
                            </ContextMenu>
                        </GridViewColumnHeader.ContextMenu>
                    </GridViewColumnHeader>
                </GridViewColumn>

                <GridViewColumn DisplayMemberBinding="{Binding a2}">
                    <GridViewColumnHeader >
                        <GridViewColumnHeader.ContextMenu>
                            <ContextMenu >
                                <MenuItem Header="Asc" />
                                <MenuItem Header="Desc"/>
                            </ContextMenu>
                        </GridViewColumnHeader.ContextMenu>
                    </GridViewColumnHeader>
                </GridViewColumn>
            </GridView>
        </ListView.View>
        <ListView.ItemsPanel>
            <ItemsPanelTemplate>
                <StackPanel Orientation="Vertical"/>
            </ItemsPanelTemplate>
        </ListView.ItemsPanel>
    </ListView>

```

The problem is that when I generate the project, I cannot see the ContextMenu (and so the MenuItems)

I already use this kind of code in another project, but here, it doesn t work...
I guess the code behind is the last one wich is generated, so if you could explain me how to create a ContextMenu programatically. Could be good.

Could you help me please ? 

Thanks !
