I have a RadGrid where the user is supposed to select more than one item (multiple). In the ViewModel I have a property called _SelectedItem with NotifyPropertyChanged. First time i click a row in the grid, I get into the _SelectedItem property setter, but if I also want to select another row, the setter of _SelectedItem property is not fired. Am I missing something? CodeBehind is not allowed in the project where this is to be used.
This is my Grid:
This is my Grid:
<
telerik:RadGridView
Grid.Column
=
"0"
Grid.Row
=
"1"
Grid.ColumnSpan
=
"4"
ItemsSource
=
"{Binding ModelCollection}"
ActionOnLostFocus
=
"None"
AutoGenerateColumns
=
"False"
CanUserSortColumns
=
"True"
IsFilteringAllowed
=
"True"
SelectionMode
=
"Multiple"
ShowGroupPanel
=
"True"
RowIndicatorVisibility
=
"Collapsed"
Height
=
"470"
CanUserSelect
=
"True"
SelectedItem
=
"{Binding SelectedModel, Mode=TwoWay}"
IsSynchronizedWithCurrentItem
=
"False"
IsReadOnly
=
"True"

After some testing, I changed the SelectionMode to "Extended", and it works now and then if I use the ctrl+click or shift+click. If I select 4 items, the count is sometimes 4, sometimes 2, sometimes 3... Is this a bug in version 2010.2.812.40? And how can I achieve my goal without keyboard interaction?

Hi Roy Halvorsen,

If you would like to select multiple items without keyboard interaction you should set SelectionMode to Multiple.
I am curious to understand which is the count that you are referring to? Is that the count of the SelectedItems property?

Yes it is. Most of the times when I loop through the selected items, it does not show all of my selected items. I have solved my selection issue by writing a behavior and SelectionMode set to Multiple, and it works the way I want it to, but that does not solve the Extended issue.

That is very strange. We would really appreciate it if you could send us a sample project that demonstrates this issue.
