Move a MapEllipse by drap And drop

Hi,

I have to show some 'POIs' on a map.
The POIs collection is bound using a typical MVVM approach.
Once the map is loaded, a 'best fit' must be applied to see all the POIs as closely as possible.
Finally, I must be able to change the location of the POIs by using drap and drop.

In my first attempt, I used MapPinPoint as elements for the POIs.
The 'move' operation was working fine, but unfortunately the GetBestView gave strange results.
(In fact I had to call it several times in order to really get the best view)
Here is the xaml for the pin point :

        <DataTemplate x:Key="ObstructionPointItemTemplate" DataType="mapLayers:ObstructionPointViewModel">
            <telerik:MapPinPoint                                        
                                        telerik:MapLayer.Location="{Binding Path=Location}"                                        
                                        ToolTip="{Binding Label}"
                                        >
                <i:Interaction.Behaviors>
                    <behaviors:PointBehavior/> <!--This behavior allows the drap and drop move-->
                </i:Interaction.Behaviors>
            </telerik:MapPinPoint>
        </DataTemplate>

Based on the decompiled code, I assumed my issue with 'GetBestView' was due to the fact that MapPinPoint wasn't a 'MapShape'
Thus, I decide to give it a chance with 'MapEllipse' :

        <DataTemplate x:Key="ObstructionPointItemTemplate" DataType="mapLayers:ObstructionPointViewModel">
            <telerik:MapEllipse Width="0.1"
                                        Height="0.1"
                                        telerik:MapLayer.Location="{Binding Path=Location}"
                                        Fill="{StaticResource PointFill}"                                        
                                        ToolTip="{Binding Label}"
                                        Stroke="{StaticResource ObstructionPointColor}"                                      
                                        StrokeThickness="2"                                
                                        >
            </telerik:MapEllipse>
        </DataTemplate>

Then the 'GetBestView()' just works fine, but unfortunately, I'm don't know how I can nicely implements the 'drag and drop' feture for MapShape.

Can you please provide some help ?

Thx

What happened with local demos?

Just upgraded to 2013.3.1204 and installing Local Demos is no longer an option. Neither during the upgrade or later after 2013.3.1204 is installed using Turn Features On/Off.

ASP.NET and Kendo still have Local Demos but not WPF. Local Demos are really useful and provide plenty of source code as reference.

If I install the click once WPF demos from the web site will I get the source code as well?

Document Assembly

I have been usingDocumentFragment to assemble a RadDocument from RadDocuments, but need to maintain the section headers from the original document. Currently they get dumped when assembling the document.

			var radDocument = RadDocumentHelper.GetDefaultDocument();
			foreach (var item in ClausesSelectedList)
			{
				radDocument = item.ClauseData.GetRadDocument(FieldOrderNumber, RevNumber.Value);
				var section = new Section();
				var frag = new DocumentFragment(radDocument);
				var docPos1 = new DocumentPosition(radDocument);
				docPos1.MoveToLastPositionInDocument();
				radDocument.InsertFragment(frag, docPos1);
			}

Dashboard DnD w/ User Controls

I am creating a drag and drop dashboard page and I need some assistance with the drag and drop from RadTreeView to Grid. My goal is to drag an item from the tree which is text base, and have it render a user control at the point of drop on the Grid.

I have been looking for an example of this with no luck and was hoping this is possible. If it is possible do you have an example project that demonstrates this?

Property FieldIndicatorVisibility doesn't work with DataTemplate

Hello,

i have a problem with the property FieldIndicatorVisibility. When i use RadPropertyGrid direct in my control, it works find, when i set FieldIndicatorVisibility="Collapsed". But when i define a DataTemplate, in which i use the RadPropertyGrid, and then use the DataTemplate in my control, the field indicator will always be shown.

Have you some suggestion for that? Thanks!

Different color of row selection

Hi,
I have a gridview attached to the list of entities using MVVM pattern.
If the user select the row, the color of the selected row is orange ( or gradient of the orange), but if the selection
of the row is by code, the color is gray.

How can you let the same color for selection?

Thanks

Performance, labels, and zooming

I think this product does not meet my needs, but I would still like answers to the following questions. If there is a better product fit, please let me know. What I want is this HeatMap display in a 2D chart.

I need to display several hundred thousand points in a heatmap, possibly several million. The product page says HeatMap can "render an obscene amount of visual detail without slowing down and without sacrificing interactivity". I am not seeing this so I would like to know what I need to change. Using 120,000 points it is pretty slow.

I wonder if the problem is the column headers. I was hoping HeatMap would act like a chart and only display "axis labels" at appropriate points, not *all* of them.

Is there any way to zoom along the x-axis? With this many points, the user will want to zoom in on specific areas.

BTW, it would be nice if we could upload zip files of projects, not just code snippets.

Public Class TempInfo

Public Property SensorIndex As Int32
