Hi,

Recently we found one show stopper bug after we moved to telerik controls version 2010.2.812. In this version TrasitionControl seems had serious changes. We use transition control inside datatemplates and rendering of views is done mostly with datatemplates.

Thanks for any help.

Exception - "Cannot resolve all property references in the property path 'Effect.Progress'. Verify that applicable objects support the properties."

Hi.

I am to provide a graph that indicate deviation from a set point.

There are five significant points on the Y axis
* Upper scale limit.
* Upper alarm limit
* The desired point (set point).
* Lower alarm limit.
* Lower scale limit.

These can be, for instance
High Scale : 100
High Alarm: 80
Set Point : 50
Low Alarm: 20 
Low Scale: 0.

They can also be,
High Scale : 100
High Alarm: 80
Set Point : 76
Low Alarm: 10 
Low Scale: 0.
 
These two sets of axis settings should draw the exact same Y Axis. Even in the case where the distance from High Alarm to set point is just 4 units and distance from Set Point to Low Alarm is 56 units, they should take equal amount of space of the drawing area. A linear dataset would draw a gently sloping curve from Low Alarm to Set Point, but it would be very steep from Set Point to High Alarm as the whole distance would be covered in just 4 units.

How do I achieve this? I consider using four stacked curves that would each cover one area of the curve on the scale for its area so that it would only APPEAR to be a single curve, but would actually be four different curves. This, however functionally adequate, does not draw a continuous curve. Any better suggestions?

I am using Telerik chart control and I want to set the minor ticks on X axis.
I tried this.

radChartROIComparison.DefaultView.ChartArea.AxisX.MinorTicksVisibility = Visibility.Visible;

But compilation fails telling that

Error 1 'Telerik.Windows.Controls.Charting.AxisX' does not contain a definition for 'MinorTicksVisibility' and no extension method 'MinorTicksVisibility' accepting a first argument of type 'Telerik.Windows.Controls.Charting.AxisX' could be found (are you missing a using directive or an assembly reference?) 

What is the reason for this????

Am I using an old version which does not support this property?

Hi,

I' ve got the following problem:

In my application there is a window which includes a scheduleview on the left side and a treeview on the right side. The scheduleview itself is inside a user control. In the scheduleview there exist some appointments.
This scenario should work, but currently doesn't:

I select one treeview item and start a drag drop operation. If I am over an appointment in the scheduleview some conditions between the appointment and the treeview item should be checked.
Currently nothing works: I start dragging the treeview item. As soon as I am over the scheduleview, a "forbidden" symbol appears, and nothing more happens.

I've implemented following:


DragQuery works, but I never reach DropInfo or DropQuery. What am I doing wrong? I have to say, that a treeview item is NOT of type Appointment.

In RadScheduler, the procedure described above worked perfectly.

Please respond soon.
Thanks

Is there an event that I can hook into to be notified when the active pane is changed in the RadDocking control? I have a ribbon that changes based on the active RadDocumentPane.

I found some similar questions in the forum with answers that suggested using the RadPane.GotFocus event. My issue with this is that I also need to properly handle when no RadDocumentPanes are active. I think the ideal solution would involve the RadDocking class having both an ActivePane property and ActivePaneChanged event.

Thanks,
Joey

I have a simple candlestick chart:

<telerik:RadChart Name="radChart1" ItemsSource="{Binding ChartData}" Visibility="{Binding CandlestickVisibility}">

        <telerik:ChartDefaultView.ChartLegend>
            <telerik:ChartLegend IsEnabled="True" Visibility="Collapsed" />
        </telerik:ChartDefaultView.ChartLegend>
    </telerik:ChartDefaultView>
    <telerik:RadChart.SeriesMappings>
            <telerik:SeriesMapping>
            <telerik:SeriesMapping.SeriesDefinition>
                <telerik:CandleStickSeriesDefinition />
            </telerik:SeriesMapping.SeriesDefinition>
            <telerik:SeriesMapping.ItemMappings>
                <telerik:ItemMapping DataPointMember="Open"
                                    FieldName="OpenPrice" />
                <telerik:ItemMapping DataPointMember="High"
                                    FieldName="HighPrice" />
                <telerik:ItemMapping DataPointMember="Low"
                                    FieldName="LowPrice" />
                <telerik:ItemMapping DataPointMember="Close"

            </telerik:SeriesMapping.ItemMappings>
        </telerik:SeriesMapping>
    </telerik:RadChart.SeriesMappings>
</telerik:RadChart>

When I go into the designer and click the IsDateTime for the X Axis, I get a Microsoft .NET Framework exception: "Specified cast is not valid"

How do I make the X Axis a datetime without blowing out the designer?

Hi Everyone, 

I am looking for a kml example to go off of.  When I follow the documentation i get nothing.  Does anyone have anything. 

Thanks,

We are building an application that uses the MVVM pattern and Prism.
Our application utilizes Rad Docking Serialization.
The application has a DocumentHost with several tabbed Panes.  When a new Pane is added to the application inside the DocumentHost, it's not initially displayed after the docking serialization is read in.  But we hook a toggle button up to each pane to control visibility and clicking the button brings the new pane into view.
Here's the problem.
When we add a new Pane outside of the DocumentHost, the trick above doesn't work.  The pane will not be seen unless the serialization is deleted.

I found mention of using LayoutSerializationLoadingEventArgs but could not find an example.
Is there an event I can catch to add the new pane to the serialization?
Or should this just work, and there's something wrong with my implementation?
Thanks

Hi,

I need to create gauges dynamically and put them in a WrapPanel. So I created a user control as follows:

The code behind looks like:
It all works fine if I add just one PercentUtilizationGauge to the WrapPanel. However as soon as I add second PercentUtilizationGauge several excaptions of type System.InvalidOperationException are thrown:

A first chance exception of type 'System.InvalidOperationException' occurred in System.Core.dll

Additional information: Sequence contains no matching element

They all seem to occur in Telerik code - the call stack looks like:

> System.Core.dll!System.Linq.Enumerable.First<object>(System.Collections.Generic.IEnumerable<object> source, System.Func<object,bool> predicate) + 0x150 bytes 
  Telerik.Windows.Controls.Gauge.dll!Telerik.Windows.Controls.Gauges.ScaleBase.FindOffPosition(Telerik.Windows.Controls.Gauges.IGaugeIndicator indicator = {Telerik.Windows.Controls.Gauges.Needle}) Line 1930 + 0x7b bytes C#
  Telerik.Windows.Controls.Gauge.dll!Telerik.Windows.Controls.Gauges.RadialScale.ArrangeIndicator(Telerik.Windows.Controls.Gauges.IGaugeIndicator indicator = {Telerik.Windows.Controls.Gauges.Needle}) Line 314 + 0xc bytes C#
  Telerik.Windows.Controls.Gauge.dll!Telerik.Windows.Controls.Gauges.IndicatorBase.ArrangeOverride(System.Windows.Size finalSize = {162,30}) Line 1121 C#
  Telerik.Windows.Controls.Gauge.dll!Telerik.Windows.Controls.Gauges.Needle.ArrangeOverride(System.Windows.Size finalSize = {162,30}) Line 94 + 0x26 bytes C#

So how do I find out what is going wrong here? Any help would be greatly appreciated.
Thanks
