How to: Check the target of Drag and Drop (OnDragCompleted)

Hi,

I have RadListBoxes and user can drag and drop stuff between them but how can I check what the drop target is when OnDragCompleted is fired?

The problem is that I want to remove data from database if user drags stuff outside the listbox but not remove data from database if user drags stuff to other listbox. I can't seem to find out which drag and drop has been done at the moment...

Now I can get the source of drag operation from sender but how can I get the target for the drop?

Editing template of RadComboBox inside RadPropertyGrid

Hi,

I have a control template that needs to be applied to all of my combo boxes in my project, including those in the property grid I have. I am using the Editable and and noneditable template to get the style that I am looking for. My property grid uses items such as textboxes, checkboxes, datetimepickers, and comboboxes. Is there a way to apply the same control template to all combo boxes that appear in my propertygrid?

Thanks

Binding CellTemplate properties to parent column's DataFormatString

I have the following CellTemplate for a few columns in my RadGridView:

<DataTemplate x:Key="TextCell" DataType="telerik:GridViewCell">

<TextBlock Text="{Binding Value,

RelativeSource={RelativeSource FindAncestor,

AncestorType={x:Type telerik:GridViewCell}}}"

TextAlignment="{Binding TextAlignment,

RelativeSource={RelativeSource TemplatedParent}}"

TextTrimming="CharacterEllipsis"

TextWrapping="NoWrap" />

</DataTemplate>

This is being applied correctly, but I need to access properties such as TextAlignment and DataFormatString that are set on the GridDataViewColumn for that cell. As you can see I've tried to access via the TemplatedParent, but to no avail. How can I access these properties, so I can use them within my template?

Thanks.

                                    ItemsSource="{Binding ChartData}"
                                    ValueBinding="Value"
                                    />

Chart Data has the values for X and Y axises. I need to show datas which represent each day of week per hour, and in one case it must be data per week

so i need to present sunday, monday ..... and whole week.

in my ChartData i put datas apropriately to my needs :

1 2 3 4 5 ... 24 --- CategoricalBinding
4 5 6 7 3 ... 221 --- Some Garbage datas

and for whole week i need have something like this :
1 2 3 4 ... 24 1 2 3 ... 24 1 2 3 ... 24 ..... 24 -CategoricalBinding for whole week this means 168 categories ( 7*24 hours)
2 1 1 1 ................... Some Garbage datas

But chart don't want to display whole week like 168 categories ( 7*24 hours), it just display 24 categories with united data.

Sorting the Data Inside Filter Popup

I have a WPF data Grid in which I have a Column called Qty having data sequnce:
2,1,4,5,3

When I click on Filter the popup also displays the data as 2,1,4,5,3. But how can it be sorted as 1,2,3,4,5

I thought of writing SortMemberPath inside <telerik:GridViewDataColumn but don't want to do that as I am not using GridViewDataColumn.

Attached the current scenario.

Column Specific Culture

I have develop a program that will be used in different countries.
We want everyone to work with date's and so on in there own culture settings.
On the other hand we can view Currency info from the differen countries. These are show in the same datagrid. I want these values to Show the right info So Euro for most Europe countries and Dollar for America.
It is only possible to select On country at a time.

Currently I am using

<telerik:GridViewDataColumn DataMemberBinding="{Binding TurnOver}" Header="Value" IsReadOnly="True" DataFormatString="{}{0:C}" >

<telerik:GridViewDataColumn.AggregateFunctions>

<telerik:SumFunction ResultFormatString="{}{0:C}" />

</telerik:GridViewDataColumn.AggregateFunctions>

</telerik:GridViewDataColumn>

How do I make it so that the rigth currency symbol and format is made on the selected country while keeping the rest of the UI the users culture setting.

This question is also for the Chart area where I use

<

telerik:SplineSeriesDefinition ShowItemLabels="False" ShowItemToolTips="True"

ItemToolTipFormat="Intake: #DATAITEM.Intake{C2}
Target: #DATAITEM.Target{C2}
Turn Over: #DATAITEM.TurnOver{C2}
Maintenance: #DATAITEM.Maintenance{C2}"/>

Telerik.Windows.Diagrams.Core
Telerik.Windows.Controls.Diagrams.Extensions
Telerik.Windows.Controls
Telerik.Windows.Controls.Navigation
Telerik.Windows.Controls.Input

Telerik.Windows.Data

is there any thing wrong? how can i use RadDiagramNavigationPane? and the same error occurs when i try to use RadDiagramContainerShape too......

i just want to make an app looks like the Demo project OrgChart, but the demo depends on too much other demos and the QuickStartFramework, is there any simply using RadDiagramNavigationPane.
