I created a simple RadChart with the following code that binds to a collection of data.  The x-axis binds to Date property of DateTIme and the y-axis binds to Quantity property of type Int.  When I try and set a property in ChartARea.AXisX, the UI is not updated.  For example, I try and set LabelRotationAngle = 45.  Nothing happens.  What I see in the x-axis since it is bound to DateTIme values, is LongDateTime format values which is making the x-axis all messy.  I set DefaultLabelFormat="dd-MMM" but the UI doesn't get updated again. 

Can anyone figure out why my chart is not getting updated in the UI.  I've looked at all the Chart Sample Demo's and my XAML looks pretty much the same.  Not sure what I'm doing wrong where the UI does not updated.

Thanks

Since this this an observablecollection, I just need to add a new TreeFolderHierarchyItem object to my observable collection
Adding new Item works fine and RadTreeView control refreshs correctly with the new item. But I want, enter in edit mode for this new item in order to change its header .
using MyRadViewTree.ItemContainerGenerator.ContainerFromIndex(0) returns always null even when all the node are expanded . So I am not able to iterate into the hierarchy ...
I thought to set IsEditMode=True but when I calls MyRadTreeVieew.Items I get my Observable collection of TreeFolderHierarchyItem  as expected but useless for setting the EditMode ..
What am I doing wrong ?
Thanks for your help

Hi

Can we set the width of the tabcontrol according to the containter Control?

For eg:
The tab control size should increase according to the usercontrol size.

Hi,

I know there is new feature in current version copy paste into excel. but i found only demo. would you please provide me example in C#.


RadControls for WPF Trial Version: 2010.2 812 

thank you.

Hello,

I would like to have the Slider thumb control move to the correct position when I set the value programmatically.  How would I go about doing this?

Thanks

Hi,
We are having trouble getting a RadDock in WPF to resize to the height/width of it's container.  We'd like it to be 100% of the grid row's height and width so it adjusts to the size of the window as it's the main area users will work in.

We want a RadRibbon to appear at the top of the screen in a manner where the user cannot remove it then have the docking area for windows appear beneath that taking up the remaining space in height.

I have a grid where the rows have a DatePicker and a DropDown. I want to disable the DropDown if the DatePicker is empty. I have this in my grid:

 

<telerik:GridViewDataColumn DataFormatString="d" Header="Termination" DataMemberBinding="{Binding TerminationDate}" >

<telerik:GridViewDataColumn.CellEditTemplate>

<DataTemplate>                                                        

<telerik:RadDatePicker x:Name="TerminationDate" SelectedDate="{Binding Path=TerminationDate, Mode=TwoWay}"/>

</DataTemplate>

</telerik:GridViewDataColumn.CellEditTemplate>

</telerik:GridViewDataColumn>

  

<telerik:GridViewComboBoxColumn                                                

x:Name="TerminationReasonType"

Header="Beneficiary Terminated"

ItemsSource="{Binding Path=ReferenceData.AllBeneficiaryTerminationReasonType}"

DisplayMemberPath="Description"

SelectedValueMemberPath="_BeneficiaryTerminationReasonTypeID.Id"

DataMemberBinding="{Binding TerminationReasonID,UpdateSourceTrigger=PropertyChanged}">


<!--
<telerik:GridViewComboBoxColumn.Style>

<Style TargetType="telerik:GridViewComboBoxColumn">

<Style.Triggers>

<DataTrigger Binding="{Binding ElementName=TerminationDate}" Value="{x:Null}">

<Setter Property="FrameworkElement.IsEnabled" Value="false"></Setter>

</DataTrigger>

</Style.Triggers>

</Style>

</telerik:GridViewComboBoxColumn.Style>
-->                                            


</telerik:GridViewComboBoxColumn>

 

 

 

I have tried the commented code but did not work. I can not reach the TerminationDate element.
Ideas?
Thx

 

 

 

 

 

I would like to open two different context menus when user righ clicks on GridView Column and GridView Row.
I take a look on samples provided and both sample has only one of the right click enabled either for GridViewRow or GridViewColumn. Please provide guidance on it.

Hi,
I just spend the whole day to find out why my RadGridView is not working like I thought it should.
No matter where and how (xaml | c#) I put my GroupDescriptions and AggregateFunctions the GridView always showed a different behaviour and never did what I wanted it to do. Sometimes the grouping failed sometimes the aggregates failed and sometimes it worked after removing and adding the groups multiple times from code-behind. I finally took a telerik sample (http://www.telerik.com/community/forums/wpf/gridview/group-header-with-aggregated-functions.aspx) and changed it to use a DataTable instead of ObservableCollection ==> and suddenly the demo worked as weird as my application. In WPF you always have to bind to the DefaultView(or any other DataView) if you want a working TwoWay-Binding to a DataTable. Because I had no more idea what to try I just bound to the DataTable instead of DataTable.DefaultView ==> and everything started working as expected.

Are DataViews not supported anymore???

Best Regards

Hi All
I have a listbox and a pie chart and you can drag from the listbox to the chart to populate it with some default values.

The scenario I am trying to actually implement is this: When the user clicks on a pie segment, a popup/new window (ideally I would like to use a DialogWindow so once the user clicks on a segment, they will be forced to edit or cancel their edit) opens up and allows the user to change the underlying data of the segment. At the same time, if the user clicks and drags the pie segment, it is removed from the chart.

I am handling all the drag and drop and the ItemClick event. The problem is that ItemClick is fired when the mouse button is pressed, NOT when it is released - that is, it responds to MouseDown rather than MouseClick. Therefore I cannot implement this scenario because as soon as the user clicks, the popup is shown and they are unable to perform any drag and drop.

In short, I would like to click and edit or click and drag. I also tried using the MouseUp event, but this is fired all over the RadChart. I want this to only happen when the user clicks on just a pie segment and so far I cannot seem to find a working solution.

Is there anyway to get around this limitation. This functionality is a requirement for us, but so far we don't seem to have a clean solution for the problem. Hope the Telerik team can give us some ideas.

Thank you very much. We are using 2010 Q1SP2 and 2010Q2Beta.
