[Solved] Synchronize RadGridView active row with DomainDatasource CurrentItem

[cachuoi]

Hi,
I use RadGridView in Telerik Q3 Beta 2009.3.916 binding to DomainDatasource and I have a problem. When I change selected item (by click or up/down arrow), DomainDatasource.DataView.CurrentItem doesn't change. Also, when I use method to move next/previous item of DomainDatasource, SelectedItem (or active item) of RadGridView doesn't change.
If I use GridView standard, SelectedItem and CurrentItem of DomainDatasource always synchronized. How can I implement to get this feature?
Thanks!

Hello cachuoi,

We are aware of this problem and will fix it as soon as possible.
Currently RadGridView is not synchronizing its CurrentItem/SelectedItem properties with the CollectionView that RadGridView is bound to.

For the time being you can use the following workaround:

public MainPage()
{
    InitializeComponent();

    this.DomainDataSource.DataView.CurrentChanged += new EventHandler(DataView_CurrentChanged);
    this.gridView2.SelectionChanged += new EventHandler<SelectionChangeEventArgs>(gridView2_SelectionChanged);
}

void gridView2_SelectionChanged(object sender, Telerik.Windows.Controls.SelectionChangeEventArgs e)
{
    this.DomainDataSource.DataView.MoveCurrentTo(this.gridView2.CurrentItem);
}

void DataView_CurrentChanged(object sender, EventArgs e)
{
    this.gridView2.SelectedItem = this.DomainDataSource.DataView.CurrentItem;
    this.gridView2.CurrentItem = this.DomainDataSource.DataView.CurrentItem;
}

Luckily the DomainDataSource provides CurrentChanged event that can be used to synchronize SelectedItem and CurrentItem of the grid. Similarly you can use the SelectionChanged event of RadGridView to updated the CurrentItem of the Domain DataSource.

All the best,
