GridViewCheckBoxColumn always initially unchecked - what am I doing wrong?

[Anders]

Hi telerik,

I have the following rather simple use of the GridViewCheckBoxColumn -- and the grid shows up with no checkmarks what-so-ever.

Can you see what I'm doing wrong?

I can see (by breakpoint) that the row data model is queried for relevant value (so binding should be correct) and that the value in all cases is True (so the underlying value is as I expect).

Any clues?

Thanks,

Anders, Denmark

Grid

        <Controls:RadGridView x:Name="grid"
                              AutoGenerateColumns="False"
                              ItemsSource="{Binding Items}"
                              Height="329"
                              ScrollViewer.HorizontalScrollBarVisibility="Auto"
                              ScrollViewer.VerticalScrollBarVisibility="Auto"
                              ShowGroupPanel="False"
                              VerticalAlignment="Top"
                              IsFilteringAllowed="False"
                              >
            <Controls:RadGridView.Columns>
                <Controls:GridViewCheckBoxColumn DataMemberBinding="{Binding IsChecked}" IsThreeState="False" Initialized="GridViewCheckBoxColumn_Initialized" />
            </Controls:RadGridView.Columns>
        </Controls:RadGridView>


"Items"

ObservableCollection<ICheckableViewModel> Items { get; set; }

Row data item


    public class CheckableStringViewModel : ICheckableViewModel
    {
        public CheckableStringViewModel(bool isChecked, string displayName, string identity, bool isReadOnly)
        {
            IsChecked = isChecked;
            DisplayName = displayName;
            Identity = identity;
            IsReadOnly = isReadOnly;
        }

        public bool IsReadOnly { get; private set; }
        public string DisplayName { get; private set; }
        public string Identity { get; private set; }
        private bool _isChecked;
        public bool IsChecked
        {
            get { return _isChecked; }
            set { _isChecked = value; }
        }
    }

Hi Anders,

We had such an issue with our previous official release Q1 2012. Could you try our latest internal build or Q1 2012 SP1 release to check whether you get the same behavior ?

Excellent!

I AM currently on Q1 2012 -- will try out the SP and either repeat my problem or mark your reply as The Answer.

So far - thanks!

[Anders]

Yes!

Upgrading to RadControls_for_WPF_2012_1_0326_Dev solved my issue!

Thanks for speedy help! I'm back on track :D
