Hi
In our application which is based on wcf data services and Entity Framework, we are using the dataservicedatasource in the mvvm pattern(with the QueryableDataServiceCollectionView object) togeher with the RadDataFilter.
the filter works great in all scenarios but when trying to retrieve data based on the "equal filter" of the property which is the primary key of the table we get this exception:
"Error translating Linq expression to URI: Cannot specify query options (orderby, where, take, skip) on single resource" (which is also the query on the loadingeventargs of the LoadingData event of the QueryableDataServiceCollectionView).
i.e. only when fetching a single data.
the Query.expression which is generated is:
Convert([10000].Where(item => (item.Company_No == 54)).Take(14)).IncludeTotalCount()

Thanks

geoserver geowebcache source

hello,
i am trying to convert a silverlight DeepEarth project over a geoserver into a WPF control. i have some problem trying to understand how the new WmsTiled Source work ( for example what kind of uri should i put in the string parameter?). Furthermore i was able to connect to a GeoWebCache using this litlle class overriding microsoft MapControl TileSource :

public class GWCTileSource : Microsoft.Maps.MapControl.TileSource

{

private const string TilePath = @"{GWC_ADDRESS}/service/gmaps?layers={L}&zoom={Z}&x={X}&y={Y}";

private string gwc_address;

private string layername;

public GWCTileSource()

: base()

{

}

public GWCTileSource(string gwc_address, string layername)

: base()

{

this.gwc_address = gwc_address;

this.layername = layername;

}

public override Uri GetUri(int x, int y, int zoom)

{

string url = TilePath;

url = url.Replace("{GWC_ADDRESS}", gwc_address);

url = url.Replace("{L}", layername);

url = url.Replace("{Z}", zoom.ToString());

url = url.Replace("{X}", x.ToString());

url = url.Replace("{Y}", y.ToString());

return new Uri(url);

}

any advice on how should i proceed to manage both wms and wms through GeowebCache sources ?

Change RadScheduleView background color cell based

We are currently developing a program using RadScheduleView. In our model any appointment can only be scheduled during user's working hours (which is user configurable).

Working hours can change from one day to another, and can be changed during program execution. We want it to be displayed behind other appointments (that is, in the background of RadScheduleView).

Is there an way to configure RadSchedule view background color in a cell independent way? i.e Working hours being displayed as green colored background cells while non working hours being displayed as gray colored cells, for example?

Thank you in advance,

Leandro

RibbonView and MVVM

Hi All,

I have a few classes that define the datacontext for controls in the RibbonView:

public class RibbonElement

{

public string Text { get; set; }

public bool IsEnabled { get; set; }

}

public class Tab : RibbonElement

{

public ObservableCollection<Group> Groups { get; set; }

}

public class Group : RibbonElement

{

public ObservableCollection<Button> Buttons { get; set; }

}

public class Button : RibbonElement

{

}

And I have several HierarchicalDataTemplates that define how the classes are visualized (modeled after the samples on this site):

<DataTemplate x:Key="ButtonTemplate">

<t:RadRibbonButton Text='{Binding Text}' IsEnabled='{Binding IsEnabled}' />

</DataTemplate>

<HierarchicalDataTemplate x:Key="GroupTemplate"

ItemsSource='{Binding Buttons}'

ItemTemplate='{StaticResource ButtonTemplate}'>

<TextBlock Text='{Binding Text}' />

</HierarchicalDataTemplate>

<HierarchicalDataTemplate x:Key="TabTemplate"

ItemsSource='{Binding Groups}'

ItemTemplate='{StaticResource GroupTemplate}'>

<TextBlock Text='{Binding Text}' />

</HierarchicalDataTemplate>

</Window.Resources>

<t:RadRibbonView ItemsSource='{Binding Tabs}'

ItemTemplate='{StaticResource TabTemplate}'

ApplicationButtonVisibility="Hidden" />

How can I create the RadRibbonGroup/RadRibbonTab controls in the templates, instead of using a TextBlock? I need to do this so that I can bind to IsEnabled to dynamically enable/disable groups. The RadRibbonTab seems to take the output of the template and put it in the group header instead of the actual RadRibbonGroup control. By contrast, the headered controls in the rest of WPF have HeaderTemplate property for headers and ItemTemplate property for items.

Can the RichTextBox be used on the server?

My company is currently looking at the possibility of combining the use of the Silverlight and the WPF RichTextBoxes (RTB).

On the client side we would have the Silverlight RTB. It would send its XAML to the server to be saved into the database.

Then from a service the XAML would be loaded into a in-memory WPF RTB and then an image of the content would be generated.

My Question is, can the WPF RTB be used in a service that does not have an interface? And if it can, Will I be able to create a RenderTargetBitmap of its visual?

How to make a 3d horizontal Bar Chart

I can't find how to make a 3D horizontal bar chart. Is there a series definition to do this? Or does anyone have instructions on how to make a Custom 3D model that can do this?

I'm using the document at

http://www.telerik.com/help/wpf/radchart-getting-started-create-data-bound-chart.html

to build a test application. I'm also using the code behind, so a piece of my code is:

{
[...]
SeriesMapping seriesMapping = new SeriesMapping();
seriesMapping.LegendLabel = "Product Sales";
Bar3DSeriesDefinition def = new Bar3DSeriesDefinition();
seriesMapping.SeriesDefinition = new Bar3DSeriesDefinition();//new HorizontalBarSeriesDefinition();//new SplineSeriesDefinition();
seriesMapping.ItemMappings.Add(new ItemMapping("Month", DataPointMember.XValue));
seriesMapping.ItemMappings.Add(new ItemMapping("Quantity", DataPointMember.YValue));
seriesMapping.ItemMappings.Add(new ItemMapping("MonthName", DataPointMember.XCategory));
radChart1.SeriesMappings.Add(seriesMapping);
radChart1.ItemsSource = this.CreateData();
}

public class ProductSales
{
public ProductSales(int quantity, int month, string monthName)
{
  this.Quantity = quantity;
  this.Month = month;
  this.MonthName = monthName;
}
public int Quantity
{
  get;
  set;
}
public int Month
{
  get;
  set;
}
public string MonthName
{
  get;
  set;
}
}

private List<ProductSales> CreateData()
{
List<ProductSales> persons = new List<ProductSales>();
persons.Add(new ProductSales(154, 1, "January"));
persons.Add(new ProductSales(138, 2, "February"));
persons.Add(new ProductSales(143, 3, "March"));
persons.Add(new ProductSales(120, 4, "April"));
persons.Add(new ProductSales(135, 5, "May"));
persons.Add(new ProductSales(125, 6, "June"));
persons.Add(new ProductSales(179, 7, "July"));
persons.Add(new ProductSales(170, 8, "August"));
persons.Add(new ProductSales(198, 9, "September"));
persons.Add(new ProductSales(187, 10, "October"));
persons.Add(new ProductSales(193, 11, "November"));
persons.Add(new ProductSales(212, 12, "December"));
return persons;
}

thanks in advance

[Solved] Multiple 3dbar series - same graph, different Z

I saw http://www.telerik.com/community/forums/wpf/chart/is-z-axis-supported-by-3d-chart.aspx some time ago, which implies that Z-Axis is not only supported, but used by default (at least for line series). However, I can not achieve this behavior using 3d bar charts. I have constructed a simple chart using multiple series, as indicated in the aforementioned post. However, the bars from different series are drawn beside each other (instead of behind eachother), just as would be if the graph were 2d.

Is using the Z-Axis no longer the default behavior? How would I achieve an effect similar to what I've described? The files attached are the charts that currently get generated. Lines do draw on top of each other (desired), but bar charts draw beside each other (not desired).

DataServiceDataSource with Linq To Sql

Hello!

We already set up a silverlight project using the DataServiceDataSource. But now, we have a project in WPF, and we are trying to implement the same scenario, but in this WPF project we are using Linq to SQL (.dbml) to generate the models.

This is a short description of the project structure:

APP (Views, ViewModels) WPF Application
Core(.dbml, partial classes, business logic etc) c# class library
Service(WCF for something that the project might have) WCF

My question is, with this architecture, how do i use the DataServiceDataSource? I realy need a service exposed to use it? it would be great if you explain it a little bit.

Looking forward to a answer.

Thanks

[Solved] ToolTipTemplate

I have this defined to let each cell display it's value in a tooltip:

<Style TargetType="telerik:GridViewCell">

<Setter Property="ToolTip" Value="{Binding Value,RelativeSource={RelativeSource Mode=Self}}" />

</Style>

It works, but for cells that have lots of content, it doesn't wrap the text. So I defined this ToolTipTemplate for the column that has lots of text:

<DataTemplate x:Key="GridViewToolTipTemplate">

<TextBlock Text="{Binding Description, Converter={StaticResource LineBreaksConverter}}" TextWrapping="Wrap" MaxWidth="400" />

</DataTemplate>

The DataMemberBinding has the same expression as the Text of the Textblock, this just allows the text to wrap. It works well, but...

I'd like to reuse this template for another column, rather than having to define this template again. I'm just not sure what to bind the Text property to so that it works for whatever column I use it with.
