SelectedItems property fro GridDataControl

[kentzheng]

Hi there, I am trying to bind SelectedItems property to a ObservableCollection in a view model with two way binding, but it looks like the ObservableCollection doesn't update when I select multiple items in the datagrid.

I looked at the grid documentation and looks like it has setter and getter, so why it doesn't work?

Thanks,

Kent

Hi Kent,

Sorry for the Delay caused,

We have analyzed your query. We don’t have direct support to bind the SelectedItems value in GridDataControl.Because SelectedItems property is not a DependencyProperty. However you can use CollectionChanged event to get SelectedItems Value.You can refer the below codesnippet to achieve your requirement.

Codesnippet[XAML]:

gdc.SelectedItems.CollectionChanged += (sender, e) =>

                {

                 

                };

 

 

If you want to bind the SelectedItems value.Please refer the below codesnippet.

Codesnippet[XAML]:

<syncfusion:GridDataControl x:Name="DataGrid" ItemsSource="{Binding GDCSource}"

                              ShowAddNewRow="False"

                              AutoPopulateColumns="False"

                              AllowSelection="Row"

                              ListBoxSelectionMode="MultiExtended"

                              local:GDCAttachedProperty.EnableSelectedItemBinding="True"

                              local:GDCAttachedProperty.SelectedItems="{Binding SelectedItems, Mode=TwoWay}"

                                   

                                    >
