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:

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

Hi,

I have used RadTreelistview  in one my project to achive Parent,child relation(Plz check attached Image).

I want the action like when i click the parent checkbox the assosiated childnode checkboxes has to check in RadTreelistview .

Pn:I have identified IsTriState property in RadTreeview to achive this,but this property is not there in RadTreelistview


Please help me.

I have a RadGrid nested within another grid.  During the DataLoading event for the main outer grid, I have setup a RowLoaded event.  In this event, the click event for the checkboxes in the inner grid are wired to the appropriate method.  However, when I run the project the click event will not fire.  Any suggestions will be greatly appreciated.  Thank you.
