ProportionalGradient on RadRadialGauge

Hi,
I'm working with RadRadialGauge and I want to color the BarIndicator with a ProportionalGradient similar to a linear gradient on more colors (Ex. green, yellow and red). I have seen that this option works on RadHorizontalLinearGauge, I would like to obtain the same thing with a RadRadialGauge.
Can someone help me?

I have attached an example of solution with the two kinds of RadGauges and an image with the desiderata.

Thanks a lot

RadCartesianChart LineSeries problem

Hello,
I am using RadCartesianChart for my project and I need to show the data I have with Line Series.
I am able to show it with BarSeries, but I cannot do the same with LineSeries.
This is my code for the data binding

<telerik:RadCartesianChart.Series>
<telerik:BarSeries CategoryBinding="date" ValueBinding="value" ItemsSource="{Binding}">
</telerik:BarSeries>
</telerik:RadCartesianChart.Series>

However, when I use the following code
<telerik:RadCartesianChart.Series>
<telerik:LineSeries CategoryBinding="date" ValueBinding="value" ItemsSource="{Binding}">
</telerik:LineSeries>
</telerik:RadCartesianChart.Series>

it gives me the error:
Error 1 Ambiguous type reference. A type named 'LineSeries' occurs in at least two namespaces, 'Telerik.Windows.Controls.ChartView' and 'Telerik.Windows.Controls.Charting'. Consider adjusting the assembly XmlnsDefinition attributes. C:\Users\.......

And in Window I only have this:
<Window ...
....
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
... />

How do I fix this?

Export to excel cell limit

Hello,

My problem is: the grid view contains cells with more than the total number of characters that an excel cell can contain (32,767 characters) and I export the data to excel with ToExcelML and I got the error at opening the result file. Is there a solution to limit just the export, without limit the grid cell?

Thank you.

[Solved] How to find selected cells after scroll?

Hi,
I have a radgridview where the user can make a random cells multiselection (see the attachment).
On the click button I need to know which cells are been selected. More specifically, for each row I need to know the item and the column of the selected cells.
If I use the radgridview.SelectedCells everything is works since the cells are visible, when I scroll the rows in the radgridview.SelectedCells they disappear.

How can I do?
Thanks
