Hi,

I have a grid view that specifies a RowDetailTemplate, something simple, like an empty grid.  Whenever I populate the ObservableCollection which is bound to the ItemsSource property of the grid, everything works fine, and the grid contains the data.  I can remove one element at a time, no problems.  Whenever I try to .Clear() the collection or .Remove() the last element, BOOM!, Object Ref Not Set...If I take off the RowDetailsTemplate, I can remove all items without exceptions.  Has anyone found a work around for this bug in the GridView?  I really need to remove all items and still have the Row Details.  Thanks for any suggestions!

Hi !

I've got a simple project with a ScheduleView in the MainWindow. The constructor code is as follows:

public MainWindow()
        {
            InitializeComponent();

            m_scheduleView.AppointmentsSource = new List<Appointment>();

            // Init the schedule view
            m_scheduleView.ViewDefinitions.Add(
                new WeekViewDefinition()
                {
                    FirstDayOfWeek = DayOfWeek.Sunday,
                    VisibleDays = 7,
                    TimerulerMajorTickStringFormat = "{0:H:mm}"
                } );
            m_scheduleView.ViewDefinitions.Add(
                new MonthViewDefinition()
                {
                    FirstDayOfWeek = DayOfWeek.Sunday
                } );

            // Make the beginning of the schedule read-only.
            var excludedRange = new ObservableCollection<Slot>();
            excludedRange.Add( new Slot( DateTime.MinValue, new DateTime( 2011, 10, 22 ) ) { IsReadOnly = true } );
            m_scheduleView.SpecialSlotsSource = excludedRange;

            m_scheduleView.ScrollIntoView( new Slot( new DateTime( 2011, 10, 23 ), new DateTime( 2011, 10, 24 ) ) );
        }

What I'm trying to do here is make the schedule read-only up to a certain date, then scroll the following day into view.
However, the last line, where I attempt to scroll a date into view, doesn't work.

Am I missing something or was this broken in SP1 ?

Thanks,
Sebastien

I have an application that has a vertical splitpanel that has two horizontal splitpanels. In the horizontal splitpanels I have RadDocking controls hat hold a viewer control that can show camera images. When docking or undockung a pane it gets reloaded, and the camera images blanks for a moment because the connection needs to be setup again. It would be nice if there is a solution for this, so if anyone has ideas please respond.

To solve this I tried setting PaneGroup.IsContentPreserved to true. This caused a nasty side effect: some of my content controls of the RadDocking did not receive resize events anymore, and they got loaded with an ActualSize of 0. So my application came up with some empty RadDocking controls while others were working correctly. After quite some time I discovered that Solution for this is to leave IsContentPreserved to false.

Just install 2011 Q2 and when I drag a column head the ghost image is 2.5 inches down and 3 inches to the right.

I'm interested in reading from a local database, as my shapefiles are far far too large to read completely into memory. I need to both do a Read() on a SqlGeospatioalDataReader based on the current view and also respond to the DynamicLayer's ItemRequest event.

How should I go about doing both these things?

This is a strange one.  We've been using RadDocking/RadPanes for a while for the main window of our application.  There were lots of problems like the window not going behind the Task Bar, etc., so we upgraded to version 2011.2.0920.40.  Now something that used to work doesn't work. 

We put controls in the header portion of the some of the panes in the dock.  One of the controls is a drop-down menu custom control, which is meant to be sort of a toolbar control that is a drop-down menu.  So you click it, and it brings up a submenu, and the user picks something.  Worked like a champ in previous versions.  Now, with 2011.2.0920.40, I click the button, and the submenu appears, but as soon as I mouse over the menu, it disappears. I have attached a picture.  I made a movie of it disappearing as well, but your site won't let me upload a .swf file.

To try and diagnose why the menu is closing, I subscribed to the SubmenuClosed event of the menu.  When my handler gets hit, the call stack is not that interesting.  I think it's too late.  Here is most of it:

Any thoughts on what would be different that breaks this scenario?  What other info do you need from me?

Thanks,

Does this work? It is not listed as a supported on the documentation, but a SQLiteDataReader is an IEnumerable, it seems. I guess I'll try it regardless. I'm attempting to create my own SpatiaLite dynamic source and I need to create RadMap compatible objects from the WKB returned.

Thanks,

I have started playing with this control.  I can not find documentation.  I did see that the windows phone version has behaviors to support Zooming. Is Zooming available in the WPF version? 

More questions to follow as I play more.... 

I would like to override the original error template to do the following
- add an warning icon at the back of the control
- add the error content to the tooltip of the icon with converter to convert the error content from error code to error message for validation from Model that implemented IDataErrorInfo interface.

I tried to do it as follows but it doesn't work. Is there anything wrong or there is another solution in handling this case?

 

<ControlTemplate x:Key="GeneralErrorTemplate">  

<Grid>

<Border BorderBrush="#66FF0000" BorderThickness="3">

<AdornedElementPlaceholder x:Name="adorner" />

</Border>

<Image Source"/Images/error.png"

ToolTip="{Binding ElementName=adorner, Path=AdornedElement.(Validation.Errors).CurrentItem.ErrorContent, Converter={x:Static con:CodeConverter.Instance}}">
</Image>
</Grid>

</ControlTemplate>

<telerik:GridViewDataColumn Header="Value" DataMemberBinding="{Binding Value, Mode=TwoWay, ValidatesOnDataErrors=True}" Validation.ErrorTemplate="{StaticResource GeneralErrorTemplate}">  

</telerik:GridViewDataColumn>

 

Hi,
I added RadPane programatically,
     myPaneGroup.Items.Add(myRadPane);
Initially, it show up fine.
Then, I close the pane (click on x button) and trying to re-add the same pane.
It won't show up the second time.

I'm trying to avoid to create a new pane everytime as it's quite heavy, instead, reuse the pane I already created.

Could you please tell me what's going on?

Thanks.
