Hi,

we would like to create a CustomControl that derives from a RadComboBox with a special ItemTemplate. On our first approach we tried it with a usual combox by adding to following lines to the Generic.xaml file of the project:

<Style TargetType="{x:Type local:ComboBoxLookupDataMaterialMainGroups}" BasedOn="{StaticResource {x:Type ComboBox}}">

<Setter Property="ItemTemplate">

<Setter.Value>

<DataTemplate >

Individual Template Definition

</DataTemplate>

</Setter.Value>

</Setter>

</Style>

It worked as expected so we changed the baseclass of the custom control to a RadComboBox, searched for the correct "BasedOn" content and changed it to:

<Style TargetType="{x:Type local:ComboBoxLookupDataMaterialMainGroups}" BasedOn="{StaticResource RadComboBoxStyle}">

Because the RadComboBoxStyle was unknown, we also added the implicit theme XAMLs

Telerik.Windows.Controls.XAML and
Telerik.Windows.Controls.Input.XAML

to the project's theme folder and added the following includes to the Generic.XAML:

<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source="Telerik.Windows.Controls.xaml" />

<ResourceDictionary Source="Telerik.Windows.Controls.Input.xaml" />

</ResourceDictionary.MergedDictionaries>

The whole project is just a WPF control assembly that is used by another WPF application project, so it doesn't contain an App.xaml file.

After starting the application it hangs with a XAMLObjectWriterException: Zeilennummer "7" und Zeilenposition "10" von "Beim Festlegen der Eigenschaft "System.Windows.ResourceDictionary.Source" wurde eine Ausnahme ausgelöst.".

Maybe it's just a small missing piece but it also might be a fundamental lack of knowledge since we are new to WPF. Could you please help us out?

Thanks!
David

displaymemberpath, autocompletemode and selection on focus

Hello,

i'm testing the autocompletebox, and so far i like it. But i have 3 questions:
1.) Is there a way to set the DisplayMemberPath? The property has no effect.
2. ) The autocompletemode doesn't work. I'm trying to use the mode "SuggestAndAppend", but it does neither. Also tried the other modes, but the control only filters the entries, but doesn't Highlight a match or autocomplete the value in the TextBox.
3.) is there am easy way to select all text on Focus?

Regards
Michael

XMLA Data Provider

Hi,
I've tried Xmla Data Provider. It works great but If I have several databases on same SSAS server, it takes always the first one.
I have a RadPivotFieldList and a RadPivotGrid: RadPivotFieldList updates fields list correctly and accordingly to the specified database/cube but RadPivotGrid connects to wrong database (the first in analysis services).

Is there a way to specify the correct catalog with Xmla data provider?
My configuration is:

<telerikDataProviderXmla:XmlaDataProvider x:Key="dataProvider">

<telerikDataProviderXmla:XmlaDataProvider.ConnectionSettings>

<telerikDataProviderXmla:XmlaConnectionSettings

Cube="MY_CUBE"

Database="MY_DATABASE_01"

ServerAddress="http://MY_WEBSERVER:8888/msmdpump.dll" />

</telerikDataProviderXmla:XmlaDataProvider.ConnectionSettings>

</telerikDataProviderXmla:XmlaDataProvider>

In this case, if I have also MY_DATABASE_00 it connects to MY_DATABASE_00.

Many thanks in advance!
Regards!

How to make the history drop down to match it's parent width?

Hi,

I am trying to make the dropdown history list's width match the breadcrumb's one. Which style or container should I overwrite to achieve this? I would like to make the breadcrumb look like the standard windows explorer one.

I suppose it is a matter of replacing a stack panel with a grid somewhere down the line, but I can't figure out where exactly. Any help is much appreciated.

Kind Regards,

Ivan.

I cannot see my connectors?

I've created a project based on your "OrgChart" sample. I'm trying to modify it so that I can see some connectors on the nodes, but I can't figure it out. Also, I need to add the connectors programmatically. How can I accomplish this?

So far I have this (for the shapes in the diagram toolbox). Not sure if this is right...

var shape = new RadDiagramShape();

shape.Geometry = ShapeFactory.GetShapeGeometry(CommonShapeType.RectangleShape);

double offset = 0.25;

foreach (var c in connections)

{

var connector = new RadDiagramConnector() { Name = name };

connector.Offset = new Point(1.0, offset);

offset += 0.25;

shape.Connectors.Add(connector);

}

var galleryItem = new GalleryItem(displayName, shape, category);

gallery.Items.Add(galleryItem);

Chart X axis text labels

Hello,

I am trying to create chart with text labels on X axis. I know about categorical chart, but in my case this is not an option and I'll tell why.
Each of my items has Count filed, CustomDate field and Label field. Count is used for Y axis. CustomDate is integer value and it is used on X axis. Label field is a string that is generated based on CustomDate and I want it to be displayed on X axis ticks, not CustomDate values. I cannot use XCategory to bind to X axis because chart can calculate difference between CustomDate values, i.e. it knows that there is difference of 5 between 5 and 10. But if use XCategory and string field it cannot calculate difference between for example "5" and "10". But this gap between values on X axis is very important.

So, is there is any possibility to use integer values on X axis using XValue, but to display string labels not these integer numbers?
