Hi,

i have a radtreeview filled with hierarchicaldata. In code i do the settings.

            _radTreeView = projectTreeView._xTreeView;
            _radTreeView.AllowDrop = true;

            _radTreeView.Drop += TreeViewDrop;
            _radTreeView.PreviewDrop += TreeViewPreviewDrop;
            _radTreeView.DragOver += ....

If i drop an item the dropevent doesnt fire. Temporarily i solved this and work with the previewdropevent. But i dont like this solution. Have anyone ideas where my problem is? Some points that i must check?

Thanks
Annett

Thanks in advance.

Hi, I have the following style set in my global resource dictionary but it is not being applied to the ScheduleView control since I upgraded to the 2010.3.1314.35 binaries. Used to work fine with version 2010.3.1110. Could someone please explain what the cause of this problem might be? I'm using the StringFormat on the binding to output just the day portion of the date but actually the whole date ('17-02-2011') is being output.

<Style x:Key="TimeRulerGroupItemBaseStyle" TargetType="scheduleView:TimeRulerItemBase">
        <Setter Property="Foreground" Value="{StaticResource RadScheduleForeground}" />
        <Setter Property="Background" Value="{StaticResource GroupHeaderHeaderBackground}" />
        <Setter Property="BorderBrush" Value="{StaticResource GroupHeaderHeaderOuterBorder}" />
        <Setter Property="BorderThickness" Value="1" />
        <Setter Property="HorizontalContentAlignment" Value="Center" />
        <Setter Property="VerticalContentAlignment" Value="Top" />
        <Setter Property="ContentTemplate">
            <Setter.Value>
                <DataTemplate>
                    <TextBlock Padding="0 3" Text="{Binding DateTime, StringFormat='dd'}" />
                </DataTemplate>
            </Setter.Value>
        </Setter>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="scheduleView:TimeRulerItemBase">
                    <Grid>
                        <Border x:Name="HeaderVisual" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
                            <Border BorderBrush="{StaticResource GroupHeaderHeaderInnerBorder}" BorderThickness="1" />
                        </Border>
                        <ContentPresenter Margin="0" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                                          VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

<Style TargetType="scheduleView:TimeRulerGroupItem" BasedOn="{StaticResource TimeRulerGroupItemBaseStyle}" />

Thanks,
Peter.

hi,
I am using the following code in aspx.cs and aspx page to turn off/on the filetring of radgrid, but its working the vice-versa. When I click on FilterOn button, filters hide and when I click on FilterOff button, filters show up. Thanks in advance.

Hey,
I've got strange issues with SelectedItem Binding of the Carousel, I believe it is due to virtualization, as when an item is visible somewhere along the rendered items, I am able to "jump" to the card of the item when I'm manipulating the SelectedItem binding.
if it's not visible than nothing is happening.

If I am correct with my assumption, how do I disable virtualization assuming this is what I need to do :)

Thanks
Ariel

Hi,

I need more information after the user changed an appointment per mouse-action (ViewDefinition = Timeline).
I have three cases:
a) the user changed the start time...
b) the user changed the position of the appointment
c) the user changed the end time...

In the AppointmentEdited-event I can´t find determination to handle the three cases.
My concret problem:
When the user changed the end time (see sample from 18. Oct to 19. Oct) the AppointmentEdited-event sends:
e.Appointment.start = #10/18/2011#  (ok), and...
e.Appointment.end =   #10/20/2011#. In my scenario I´m working with "full days"  (SnapAppointments="True") and i need  #10/19/2011# as end time. Thanks in advance for your feedback.


kindly regards,
Stefan

I'm trying to use the RadDocking for its tabs that can be peeled off into new windows- ideally when this is done I'll have something like Chrome or IE's tabs. I know it's not a perfect match, but I don't know of any other controls that work better for this. 

My specific problem, is that when I drag a tab out of its tab strip, it floats immediately, and I don't know how to catch an event for "dropping" it- letting go of the mouse in a non-docking region. I'm hoping that I can detect the drop, rather than the pick up, because I need to build a new window around floating tabs, but I also need to make sure not to "window in" tabs in transit to other docking areas.

For reference, my current (non-working) code is below. Its problem is that I never get a chance to move tabs to existing dockin gregions, it always makes the new window.


Also, if you can think of a better way to make a draggable tab interface than using RadDocking, please let me know.

Hello,

how can I set the font-family for all Telerik controls in my WPF project centrally?

Is there a way to override the Segoe font with Calibri?

THanks
