Does the CheckListBox support Shift Range Select?

[Declan Hillier]

I'm confident I can write the code to handle this manually but thought I'd ask if there was a built in property first.

I want the user to be able to check/uncheck (n.b. not Select/Unselect) a range of items in a check list box.  e.g. if the user check the 2nd item and then shift checks the 5th, it should automatically check Items 3 and 4.

Is their a built i

Thank you.  That's really great news that it'll be made part of the library.

In the meantime I have coded up a reasonably simple solution that others might find useful:-

        private IdAndDescription mLastOption1ScenarioChecked;

        private bool mEditingOption1Scenarios;

        private void Option1ScenariosCheckedListBox_ItemChecked(object sender, Syncfusion.Windows.Tools.Controls.ItemCheckedEventArgs e)

        {

            if (Keyboard.Modifiers == ModifierKeys.Shift && !mEditingOption1Scenarios)

            {

                IdAndDescription firstItem = Option1ScenariosCheckedListBox.Items.Cast<IdAndDescription>().FirstOrDefault(i => i == mLastOption1ScenarioChecked || i == e.Item);

                IdAndDescription lastItem = Option1ScenariosCheckedListBox.Items.Cast<IdAndDescription>().LastOrDefault(i => i == mLastOption1ScenarioChecked || i == e.Item);

                mEditingOption1Scenarios = true;

                Option1ScenariosCheckedListBox.SelectedItems.Clear();

                for (int i = Option1ScenariosCheckedListBox.Items.IndexOf(firstItem); i <= Option1ScenariosCheckedListBox.Items.IndexOf(lastItem); i++)

                { Option1ScenariosCheckedListBox.SelectedItems.Add(Option1ScenariosCheckedListBox.Items[i]); }

                mEditingOption1Scenarios = false;

            }

            mLastOption1ScenarioChecked = e.Item as IdAndDescription;

        }

Set the method as the item checked handler for the checked list view and it works fine (you'll have to adjust the object types as appropriate).
