ADOMD Empty Grid

I'm testing out the pivot grid control and adapted the sample to use adomd.

The problem is when I run it, I get no fields in the picker. Everything is empty. No errors, no extended errors in VS when debugging.

I can verify my connection string is working because I can create an AdomdConnection using Microsoft's API and successfully connect to the SSAS server and see the connection metadata/properties while it's open when debugging with VS.

SASS is 10.50.1600.1,
Microsoft.AnalysisServices.AdomdClinet is v 10.0
WPF 4.0

Not sure why I'm not getting anything using the telerik control.

Adding Groups Programmatically

Hi,

I am trying to build a rad grid view dynamically and I have a slight issue with the column groups.

When the table is shown not all of the groups are shown but when I scroll they appear (only the first 10 get drawn when the grid is first loaded).

I have tried tow different approaches to make this work;

Extending RadGridView and building the table based on a dependency property that contains the details of what columns/groups need to be added and,
Moving the dependency property up a level and working with an out of the box RadGridView.

Do you have any suggestions of what I can do to get all of the column groups to be drawn when the grid view is first loaded?

Thanks,

Steven

How to make Column aligned aggregates in grid view

I just updated to the newest version and went through the release note. The change "Column aligned aggregates" in GridView caught my interest, but I seem to be unable to find anything usefull when I search for that term anywhere (also in the documentation).

There were no link in the release note to take me to a detailed description of this change.

How and where do I find the documentation of this?

Thanks

Binding Single Objects to a RadCartesianChart's BarSeries

Hey there, I'm creating a project where I want to display attributes of specific objects in a chart. For example, I have 2 different loan objects (Current Loan and Proposed Loan) and I want to display each one of those object's "Tax Savings" in a bar chart. I am trying to do something EXACTLY like this:

http://www.telerik.com/help/wpf/radchartingkit-series-barseries.html

But I want the properties themselves to be properties on my objects. I've tried basic bindings and I can't seem to get it to work. The objects bind find throughout my app it's just not functioning here. The code I've got is:

<telerikChart:RadCartesianChart Width="500" >

<telerikChart:RadCartesianChart.HorizontalAxis>
<chartView:CategoricalAxis/>
</telerikChart:RadCartesianChart.HorizontalAxis>

<telerikChart:RadCartesianChart.VerticalAxis>
<chartView:LinearAxis/>
</telerikChart:RadCartesianChart.VerticalAxis>

<telerik:BarSeries>
<telerik:BarSeries.DataPoints>
<telerik:CategoricalDataPoint Value="{Binding Path=CurrentLoan.TaxSavings}"
Category="Proposed Loan"/>
<telerik:CategoricalDataPoint Value="{Binding Path=ProposedLoan.TaxSavings}"
Category="Current Loan"/>
</telerik:BarSeries.DataPoints>
</telerik:BarSeries>

</telerikChart:RadCartesianChart>

When It loads, it actually blanks out my entire "View" that the charts are supposed to be in. Any suggestions? Thank you

Binding columns to view model

I'm currently evaluating TreeListViews from various vendors and am trying to determine if what I'm looking for is possible. We are using an MVVM model for our code. That being said I have a view model that has a collection of items. Each item has a collection of children and a collection of additional properties. Below is some sample code:

public class PsuedoClass

{

public IObservableCollection<IBaseClass> Parents { get; set; }

}

public class Parent : IBaseClass

{

public String Name { get; set; }

public IObservableCollection<IBaseClass> Children { get; set; }

public IDictionary<string, string> OtherData { get; set; }

}

public class Child : IBaseClass

{

public String Name { get; set; }

}

public interface IBaseClass

{

String Name { get; set; }

}

Now obviously this code isn't complete, but I wanted to give you an idea of the basic structure. Now I want to display this in a TreeListView where each row has a choice of a couple templates, one template for if its a Parent, the other if its a child. And then I want the columns to be bound to the "OtherData" in the Parents class (Meaning, I want the Header to be the "Key" in the dictionary and the data to be the "Value" of the dictionary, or some similar structure).

What I would like to be able to do is something like this:

<UserControl ... >

<UserControl.Resources>

<DataTemplate x:Key="ChildItemTemplate">

<TextBlock Text="{Binding Name}"/>

</DataTemplate>

<HierarchicalDataTemplate x:Key="ParentItemTemplate"

ItemsSource="{Binding Children}"

ItemTemplate="{StaticResource ChildItemTemplate}">

<TextBlock Text="{Binding Name}"/>

<SomeHowDisplayTheRestOfTheColumns/>

</HierarchicalDataTemplate>

</UserControl.Resources>

<telerik:RadTreeListView ItemsSource="{Binding Parents}"

Columns="{Binding SomePropertyThatExposesOurColumns}"

ItemTemplate="{StaticResource ParentItemTemplate}">

</telerik:RadTreeListView>

</UserControl>

Any insight into if this is possible with examples would be greatly appreciated. Thanks in advance.

All Other Items Become "Disabled" When DropDown Is Open

Telerik Support,

When a user has the DropDown to a ComboBox open, it becomes impossible to focus/click on any other element (seemingly in the entire program) until the DropDown is closed. I understand that this is the standard behavior even with the regular WPF ComboBox control, so what I'm wondering is if there's any way to change this behavior.

Thanks,

Kyle

How to disable radtreeview validation

I am binding my radtreeview to a collectionviewsource that is grouped on the employee's last name initial (A, B, C, etc.). I also bind the selecteditem to a property on my viewmodel which is of type Employee. The problem is that when I select the parent node (A, B, C, etc.) it fails validation and gives me a red border. I want to override that and disable it.

Private _selectedItem As Library.EmployeeInfo

Public Property SelectedItem As Library.EmployeeInfo

Get

Return _selectedItem

End Get

Set(ByVal value As Library.EmployeeInfo)

If IsBusy Then Return

_selectedItem = value

NotifyOfPropertyChange(Function() SelectedItem)

Events.Publish(New SelectionChangedEvent(Of EmployeeListViewModel, Library.EmployeeInfo) With {.Source = Me, .Obj = Me.SelectedItem})

End Set

End Property

<Grid.Resources>

<bengenconv:SingleCharacterConverter x:Key="SingleCharacterConverter" />

<CollectionViewSource x:Key="Emps"

Source="{Binding Model}">

<CollectionViewSource.SortDescriptions>

<componentModel:SortDescription PropertyName="Lastname" />

<componentModel:SortDescription PropertyName="Firstname" />

<componentModel:SortDescription PropertyName="EmployeeIdNumber" />

</CollectionViewSource.SortDescriptions>

<CollectionViewSource.GroupDescriptions>

<PropertyGroupDescription PropertyName="Lastname"

Converter="{StaticResource SingleCharacterConverter}" />

</CollectionViewSource.GroupDescriptions>

</CollectionViewSource>

<DataTemplate x:Key="EmployeeTemplate">

<TextBlock>

<TextBlock.Text>

<MultiBinding StringFormat="{}{0}, {1}">

<Binding Path="Lastname" />

<Binding Path="Firstname" />

</MultiBinding>

</TextBlock.Text></TextBlock>

</DataTemplate>

<HierarchicalDataTemplate x:Key="GroupsTemplate"

ItemsSource="{Binding Items}"

ItemTemplate="{StaticResource EmployeeTemplate}">

<StackPanel Orientation="Horizontal">

<TextBlock Text="{Binding Name}"/>

<TextBlock Text="{Binding ItemCount, StringFormat=' ({0})'}"

FontSize="11"

FontStyle="Italic"

Foreground="DimGray"

VerticalAlignment="Center"/>

</StackPanel>

</HierarchicalDataTemplate>

</Grid.Resources>

<telerik:RadTreeView x:Name="xTreeView"

ItemsSource="{Binding Source={StaticResource Emps}, Path=Groups}"

Grid.Row="1"
