Tiled layer

Hello,

Is it possible to have a tiled layer mechanism as you can do for providers? I currently have a bing map provider, but want to overlay them with a tiled source, ie images served from a webservice according to coordinates and zoomlevel.
So in my case it's not possible to use another provider, as I still need to see the bing maps underneath the (semitransparent) tiled images.
I read in this post that multiple layered tile providers were not possible, but is planned in a future release.

In Bing maps this was possible using a Microsoft.Maps.MapControl.LocationRectTileSource.
I see i Telerik a class TilesVisualizationLayer, but it says it's for internal use, and I can't find an example of how to use it?

Is this scenario possible in Telerik maps, and if so: could you point me to an example to analyse?

Thank you,
Tom

add close button a tileview header when using Prism and RadFluidContentControl

Hello;

I would like to remove a tile view dynamically in a wpf project using Prism to inject the views as data and look is different per view. It is working when tileviews are created in view model with simple header and content by updating header style and associate a command to the close button, but this is not working with Prism framework. How can I get the existing tileviewitems in an observable collection and remove one when we click on close or cross button from the differents views (large, small, normal) ?

Thanks for your feedback.

Typing over selection problem

Hi,

We currently have a problem with the RichTextBox when someone tries to type over selected text. If the text is selected and the first letter they type is a capital letter it will sometimes re-select text and any further typing will crash the program with this error.

"inline does not belong to this document."

When typing all lowercase with selected text this doesn't seem to happen. It also appears to work properly when using delete or backspace and then typing the text.

If someone could let me know if this is a known issue or if there is a solution to this problem it would be greatly appreciated.

Thanks,
Aaron

save tileview item position in Prism framework

Hello;

I am working with telerik WPF tileview and Prism framework to generate a dashboard with different views content in large, small & normal view.
I would like to save the position of the tile view if the user reorder the different views so that this order is used in the next connexion. How to do that ? I search many posts and the given solutions are quite simples since they deal with tileview without prism framework.
Please let me know if it is possible to do this in my context ?

Thanks

Data Filter and Inheritance

Hello,

I'm working with a RadDataFilter and a GridView, in the following manner:
XAML :
<telerik:RadDataFilter Grid.Row="0" x:Name ="radDataFilter_Report" Source="{Binding TaskReportsItemsSource.View }" />
<dataGrid:ThemeDataGrid Grid.Row="1" ItemsSource ="{Binding FilteredSource, ElementName= radDataFilter_Report}">

Where as in the ViewModel:
private readonly ObservableCollection<IDerivedClass> TaskReportsItemsSource = new ObservableCollection<IDerivedClass>();

and the DerivedClass is:

public interface IDerivedClass: IBaseClass1, IBaseClass2, IEquatable<IBaseClass2>, IBaseClass3, INotifyPropertyChanged
{
ISomthing Something {get;set;}
bool IsMessageUnread {get;set;}
Enum1 ManagerDecision {get;set;}
Enum2 Status {get;set;}
}
In the filter fields list I can only see the fields from IDerivedClass and none of any of the base classes

How can I get all the fields ( the derived and all base classes)?
Thanks a lot,
Liora

Cartesian Chart Only Shows 1 Value

I have a problem working with a LineSeries in a RadCartesianChart: my binding series has 10 values, but the chart only shows 1 of them.

What could be the problem in my code?

XAML:

<telerik:RadCartesianChart x:Name="chPrueba" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Width="972" Height="477">

<telerik:RadCartesianChart.Grid>

<telerik:CartesianChartGrid

MajorLinesVisibility="XY"

StripLinesVisibility="Y"

MajorXLineDashArray="10, 5"

MajorXLinesRenderMode="All">

<telerik:CartesianChartGrid.YStripeBrushes>

<SolidColorBrush Color="#FFDFDFDF" Opacity="0.3" />

<SolidColorBrush Color="Transparent" />

</telerik:CartesianChartGrid.YStripeBrushes>

</telerik:CartesianChartGrid>

</telerik:RadCartesianChart.Grid>

<telerik:RadCartesianChart.VerticalAxis>

<telerik:LinearAxis

Minimum="0"

Maximum="100" />

</telerik:RadCartesianChart.VerticalAxis>

<telerik:RadCartesianChart.HorizontalAxis>

<telerik:CategoricalAxis LabelOffset="0" LastLabelVisibility="Visible"

LineThickness="1" MajorTickOffset="0" MajorTickInterval="1"

PlotMode="BetweenTicks" TickThickness="1" ZIndex="0" LabelFitMode="Rotate"/>

</telerik:RadCartesianChart.HorizontalAxis>

<telerik:LineSeries x:Name="chLineSeries" CategoryBinding="fecha" ValueBinding="valor" AllowSelect="True" Stroke="#FF0DAE0D"/>

<telerik:RadCartesianChart.Behaviors>

<telerik:ChartTrackBallBehavior ShowIntersectionPoints="True"/>

</telerik:RadCartesianChart.Behaviors>

</telerik:RadCartesianChart>

Data Class:

public class vAbortos

{

public Double valor { get; set; }

public String fecha {get; set;}

public vAbortos()

{

}

Creating the data and loading it to the chart:

public void WindowLoaded()

{

List<vAbortos> valores = new List<vAbortos> { };

Random rnd = new Random();

DateTime fc = new DateTime(2013, 12, 1);

for (int i = 0; i <= 9; i++)

{

vAbortos ab = new vAbortos();

ab.fecha = fc.AddDays(1).ToShortDateString();

fc.AddDays(1);

ab.valor = rnd.NextDouble() * 10;

valores.Add(ab);

}

this.chPrueba.Series[0].ItemsSource = valores;

(chPrueba.VerticalAxis as LinearAxis).Minimum = 0;

(chPrueba.VerticalAxis as LinearAxis).Maximum = 15;

}

Round Off Issues in RadMaskedTextBox

Hi,

We are using RadMaskedTextBox in our application. We have faced Round Off issues with RadMaskedTextBox.

Below are the issues :-

1)When we are entering values into RadMaskedTextBox , we can only enter the number of decimals in the Mask and it does not round, if we continue to type numbers, the last digit will keep changing to whatever we are typing.

2)When we copy and paste values from say Excel or Notepad that contain more digits after the decimal than what we set in the mask. , the value is not rounded, instead, the last digit in the number being pasted is the last digit displayed. i.e. if we paste the value 1.10003 and we have selected 2 decimal places in 1.2.2, the value will be displayed as 1.13, not 1.10 which is the rounded value.

Please help us to figure out this issues.

Thanks.
Wayne
