I have an InformationLayer that contains points through a LocationCollection property in a view model. When I call the Clear() method on the LocationCollection, the lines on the map don't go away (even if I zoom in or out). My InformationLayer XAML looks like the following. As mentioned, MyPolyline is a LocationCollection:

<telerik:InformationLayer>

<telerik:MapPolyline Points="{Binding MyPolyline}" Fill="Transparent" Stroke="Teal" StrokeThickness="1" />

</telerik:InformationLayer>

It appears I'm running version 2011.2.920.40. I have confirmed the MyPolyline.Count property is 0 after calling the Clear() method, but as mentioned, the lines on the map don't go away.

UriImageProvider and RenderOptions

Based on a recent response, I now understand that you use the WPF Image class for rendering the underlying image specified in the UriImageProvider. However, on large images I run into performance issues. Normally, I can use something like:

RenderOptions.SetBitmapScalingMode(oImage, BitmapScalingMode.LowQuality)

But I am not sure how to do this when working with the UriImageProvider.

Thanks,
Seth

SortDescriptor removed when click on column header

I am using SortDescriptor for multi column sorting in TreeListView. My requirement is there is a context menu appearing on columns cells with option like "Sort Ascending" & "SortDescending". When user right click on any cell then i find the corresponding column and add to SortDescriptor. So now when i add the column to SortDescriptor then the column header is highlighted with a small tringle. This is working fine for multiple columns.

My Problem is suppose I have 10 columns out of which I have added three columns to SortDescriptor and now 3 column header are highlighted. This is done by right click context menu. Now user directly click on 4th column header to sort. In that case the previous 3 columns are removed from SortDescriptor automatically and the user clicked column only highlighted. In my case I need to show all those 4 columns highlighted with 4 values in SortDescriptor. Please help me how I will be able to do.

Thanks

Custom Links

Hi,
we are evaluating RadRichTextBox at the moment, because we have some specifice requirements.

We wanna show a textbox where the user can enter simple text, but furthermore we have some custom links in the text. This links point to another item in our application.

This can look like this:

"[X] is doing [Y]" where [X] and [Y] are two links. The source of this links are simple Ids, but we also wanna shows some custom tooltip.

I guess that I can do this using a InlineUIContainer.

The second requirement is that we wanna support Intellisense for the links, how can we do this and is there any example for this requirement?

ScaleVisibility bug?

On our RadMap we have some layers. The layers contain some objects/mapItems.
All these objects have tooltips and when moving the mouse over an object the cursor changes to a hand-cursor and the ToolTip shows..

This works fine.
But...
When ScaleVisibility = "Visible" this won't work for objects which are placed in the bottom of the map. Or you can say: it doesn't work for objects lying on or under the same height as the ScaleBar.
When ScaleVisibility = "Collapsed" all the objects are working OK.
Could this be a bug in the z-index of the Scalebar?

For your information:
<DataTemplate.Triggers>
<Trigger SourceName="pin" Property="IsMouseOver" Value="true">
<Setter Property="Cursor" Value="Hand"/>
</Trigger>
</DataTemplate.Triggers>
