Hi,
Can you explain the following settings; the documentation is not very clear
AutoCalculateClusteringThreshold = true;
ClusteringEnabled = true;
ClusteringEnabledThreshold = 18;
ClusteringEnabledThresholdMinItems = 100;
I have changed my code to use the VisualisationLayer instead of a DynamicLayer to try and improve performance. I used to handle the clustering of my points in the code, but now want to use your mechanism.
My datasource may contain say 5000 pin points, all in the uk.
When I zoom to see all of the uk, I would like the points clustered
When I zoom in, I would like to see the points clustered until we get to a point where we can safely display the points e.g. if there are less than 100 visible points in the viewport.
At the moment, I seem to get clustering all the time, and it shows clusters even when there is just a single point
Thanks
Simon

Hi,
is there a way to achieve that the validation error tooltip is not only shown if the mouse cursor is within the red triangle in the upper right corner of the cell but also when it is somewhere else in the area of the invalid cell? I need this behaviour especially in non-edit mode.
Regards Uli

I used RadPdfViewer in WPF. I put the pdfviewer in grid. I set the height="*". But the problem is, the pdfviewer extends beyond the screensize of the window and the scrollviewer also not working. Help me to fix it. I have attcached the Snapshot of the window.
<Grid >
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<telerik:RadPdfViewer Grid.Row="0" x:Name="pdfViewer1" DocumentSource="{Binding url1}" telerikControls:StyleManager.Theme="Expression_Dark">
</telerik:RadPdfViewer>
</Grid>
<Grid >
<Grid.RowDefinitions>
<RowDefinition Height="*" />

We are drawing a RadCartesianChart using a StepLineSeries. So far so good.
How can we make the last step go until the end? Say our last data point is at (8;1) and the end of the x-axis is at 10. How can we make the ChartView draw a line from 8 to 10 to depict the last step (we would not like to add an additional point at (10;1).
See screenshot...

Hi @ all,
is there already a build-in localization for the ExpressionEditor? I just found this post for silverlight, which also works for WPF.

Hello Team,
Please help me to resolve the below two issues in PivotGrid.
1. Ability to sort aggregate columns doesn't work.In the calculation If you choose highest to lowest A.) it doesn't work B.) it won't allow us to keep the number format you desire. In the example below I want to keep % and rank highest to lowest. Please see the attached image (image1.png).
2. Cannot use the same field twice (i.e, we cannot add a column in both Row Labels and Report Filter) This is extremely limiting. Please see the below image (image2.png).
If we achieve the above two, then we can generate more reports easily with Pivot Grid. Please help me to resolve the above two.
Regards,
Shahrooz

Hello,
I implement a WPF Application with RadGridView. Some columns are invisible and selectable. But I have also columns that must be unvisible and not selectable.
How could I achieve this behavior?
Thanks a lot in advance!
