Reorder RadGridView Rows inside a RadLayoutControl doesn't work

Hey community,
the row redorder sample doesn't work within a RadLayoutControl. It looks like as if the RadLayoutControl would intercept the DragEvent, so the GiveFeedbackEventArgs is not called within the RowReorderBehavior.
Can you provide me asample or give me a hint please.

I've tried it with this sample:

http://docs.telerik.com/devtools/wpf/controls/dragdropmanager/how-to/howto-draganddrop-within-radgridview

Kind regards,
Lars

Item Added To Group Event?

Hi,

I would trace in a RadTreeView the structure Groups/Items, wher Groups is first level and Items second one.

I thought that I could intercept "Item Added To Group event", can I do this in somehow?

Two cases I shuold keep:

I drag and drop 2 or more objects into RadDiagram, add theme both and create a group for theme.
I have already 2 or more objects into RadDiagram, user selects theme and clicks "Group Items" command.

Finding Row, Column, Overall Averages

Hi,

firstly thanks so much for the work you've done in providing the Pivotgrid. It has great functionality straight out of the box and our clients will love it!

My query is about row and column averages. I basically want to be able to highlight specific cells that fall below a row or column average. I know how to use the CellTemplateSelector to change the colour but don't know how to actually find the row, column or overall average so that I have an average threshold to compare the cell value against. For example, take the following grid...

Q1 Q2 Q3 Q4

Fred 2 6 7 9

Wilma 10 10 3 9

How would I work out that Fred's average is 6 (2+6+7+9 / 4) or that the overall average is 7 (2+6+7+9+10+10+3+9 / 8) so that I can highlight the cells falling below the average?

Thanks for any help here : )

Iain.

RadDataFilter: limit depth of filters tree

Hi, we are using telerik RadDataFilter but we do not want the user to be able to create an infinite-depth tree of filters (we think an excessive deep tree makes the UI messy and can get the filtering too complicated). We'd like to limit the depth in a way that after, let's say, 5 level of filters nesting, the user can't be able to generate a new level by clicking on the last green button of the filter, possibly hiding the button or cancelling some way the operation. We couldn't find a way to achieve our goal.

Thanks in advice!

RadComboBox Cell And Scrolling

Hi,
In my GridViewDataColumn I set following CellTemplate:

<StackPanel Orientation="Horizontal">
<telerik:RadComboBox IsEditable="True" x:Name="rcb"
DisplayMemberPath="Name"
Loaded="RadComboBox_Loaded"
Text="{Binding State, Mode=TwoWay}" Width="100"/>

<TextBlock Text="{Binding ElementName=rcb, Path=Text}" Margin="2 0" Width="100"/>
</StackPanel>

and the RadCombobox Items can be Following Values:
VeryBad, Bad, Good Plus, Good Neg, Good, ...

I set value of the first cell to Good
(=> RadComboBox and TextBlock Both show Good)
but when I scrolling
the text of RadCombobox change to Good Plus
but TextBlock Shows Good.

Theme Visual Studio 2013

Hi,

Following the steps of the documentation I installed the theme of visual studio 2013:

http://docs.telerik.com/devtools/wpf/styling-and-appearance/styling-apperance-setting-a-theme-overview

The problem I have is that it works for me in all grids except one that I have filters (I do not know if it has anything to do with).

As you can see in the picture 1.png works fine.

In the 2.png image we can see that the theme is applied in the grid header, but the shading and selection are of a different color (I guess the default theme). The same thing happens in the 3.png image that belongs to RadContextMenu, the shading is not of the visual studio 2013 theme.

<telerik:RadGridView Grid.Row="1" Name="DatagridResults" FilterOperatorsLoading="DatagridResults_OnFilterOperatorsLoading" Filtering="DatagridResults_OnFiltering" Filtered="DatagridResults_OnFiltered" ItemsSource="{Binding OptimizerResults}" helpers1:BarLogColumnsBindingBehavior.Columns="{Binding ResultsOptimizerColumns}" Loaded="DatagridResults_OnLoaded" MouseDoubleClick="ResultsOnMouseDoubleClick" Sorting="DatagridResults_OnSorting" Sorted="DatagridResults_OnSorted" ShouldCloseFilteringPopupOnKeyboardFocusChanged="True" IsReadOnly="True" ShowGroupPanel="False" CanUserDeleteRows="False" CanUserInsertRows="False" AreRowDetailsFrozen="True" CanUserReorderColumns="False" CanUserResizeRows="False" CanUserResizeColumns="False" RowIndicatorVisibility="Collapsed" IsFilteringAllowed="True" EnableColumnVirtualization="True" FrozenColumnsSplitterVisibility="Collapsed">

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu ItemsSource="{Binding MenuItemContextMenuItemsCollection}" >

<telerik:RadContextMenu.ItemContainerStyle>

<Style TargetType="telerik:RadMenuItem">

<Setter Property="IsCheckable" Value="True"/>

<Setter Property="IsChecked" Value="{Binding IsChecked}"/>

<Setter Property="Command" Value="{Binding Command}"/>

<Setter Property="Header" Value="{Binding Header}"/>

<Setter Property="CommandParameter" Value="{Binding RelativeSource={RelativeSource Self}}" />

</Style>

</telerik:RadContextMenu.ItemContainerStyle>

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

</telerik:RadGridView>

Do you think it may be happening? Thank you.

Regards,

Gerard.

Show miliseconds on timeline in GanttView

I was planning to use Winform-Gantt View. but I heard that recurring task is not supported in Winform Gantt-View.
(http://www.telerik.com/forums/show-multiple-tasks-on-one-line-in-gantt-view)

Thus, I change my plan to apply WPF GanttView for my project.
I tried many things using Telerik WPF demo for applying our project.
but I have some problems to do it.

1. Is it possible to show miliseconds timeline in a Gantt View?

I can only show in the minimum timeline as a minute (day:hour:01)
Is it possible to show miliseconds? or in a second?

2. In the recurrent task, is it possible to custom move? (not all just one task)

Thanks , Hyeon

TabItem Template

I must be missing something simple. I'm just trying to work with the background colors for the TabItems. I've made a Control Template and Style. When I explore the Live Visual Tree, I find that BorderVisual is being defined from the default Implicit Styles file. Everything else above seems to be pulling correctly from the Style and Template I've made. What am I doing wrong?
