in reality ,i need the selected object of the columnlayout to modify just a colmn in it ,but by a popup .Thanks

I'm working with MVVM .So i need the selected object in this Columnlayout to modify it;not by editing in the xamgrid directly

Hi Mesnel,

We also need the "ActiveItem for ColumnLayout" feature.

We understand it is not easy as object type can be different for each level.

Anyway, we used this workaround :

• register to "SelectedRowsCollectionChanged" event
• update selected object manually

Code example :

public PageConstructor()
{
   
    this.DataContext = new MyViewModel();
    this.MyXamGrid.SelectedRowsCollectionChanged += new EventHandler<SelectionCollectionChangedEventArgs<SelectedRowsCollection>>(MyXamGrid_SelectedRowsCollectionChanged);
 }
 
void MyXamGrid_SelectedRowsCollectionChanged(object sender, SelectionCollectionChangedEventArgs<SelectedRowsCollection> e)
{
    if(e.NewSelectedItems.Count > 0)
        ((MyViewModel)this.DataContext).SelectedElement = (MyElementType)((RowBase)(e.NewSelectedItems[0])).Data;
    else
        ((MyViewModel)this.DataContext).SelectedElement = null;
}

Look likes the event is firered after everything else, so we can, at the end, update "SelectedElement".

Hope this will help you.

Alain.
