Hello,

I'm having trouble understanding the DeleteBehavior, BackspaceBehavior, and DeleteSelectedBehavior properties in annotations.  They do not seem to be working how I would expect them to.

I would like to have a custom annotation that works almost exactly like a read-only annotation range, but I would like to be able to select and delete the entire annotation range, including the text, from the UI.

I assumed that I would be able to customize this behavior by setting the DeleteBehavior, BackspaceBehavior, and DeleteSelectedBehavior, but it doesn't seem to work regardless of what settings I specify in those overridden properties.

Is it even possible to do what I am asking?

Thanks,

Frank

I have implemented the use of the 2D chart (bar, line, splinearea, splineseries) in software and have no problems setting the graphing color fill for each series in the charts data set.  I was hoping that the 3D chart used the same methodology but this does not appear to be the case.  I need to be able to set each series to a user chosen color.  It should not be this hard but I can't find any information on how to set up each series.  It appears that the chart just picks each color automatically without giving the ability to have it manually set.  Please help! 

The way that I set the color with the 2D charts is as follows:

 lineSeries.Definition.Appearance.Stroke = new SolidColorBrush(Colors.Blue);
 lineSeries.Definition.Appearance.Fill = new SolidColorBrush(Colors.Blue);

If I change the lineSeries type to Line3DSeriesDefinition then the default aqua color that comes up with the examples is used even when the color Blue is set as defined above.

Thanks for any help that can be provided!

I need to know how to set the background color of the charting area of a 3D chart.  For the 2D chart I create a MarkedZone object and apply a solidcolorbrush as follows:

 MarkedZone bgZone = new MarkedZone();
 bgZone.Background = new SolidColorBrush(Colors.Aqua);
 this.radChart1.DefaultView.ChartArea.Annotations.Clear();
 this.radChart1.DefaultView.ChartArea.Annotations.Add(bgZone);

This does not work for the 3D chart!  How would I make this work for the 3D chart or is it even possible.

Thanks,

James

Hi,

I have made a DayTemplateSelector - allowing me to style the calendar (highlighting different dates with colors..).
This works fine with all the different themes except the "Expression_Dark" theme (the dates are not highlighted with my color)
See attached images...(with and without "Expression_Dark" theme)
1. Any ideas why this theme is different from the others?

2. How can I decrease the height/width on the areas that show day/weeknumber?
They take up way too much space...(I have marked the areas with green color on image: RadCalendar - DayTemplateSelector 2.png)

In a current project, we've used the TreeListView to display hierachical data (sreenshot attached).

What we want to do is to expand all lines of a specific level.
For example (see screenshot) :
 > when the user clicks on button "1", all "level 1" lines should expand
 > when the user clicks on button "2", all "level 1 and 2" lines should expand
etc.

We've succeeded doing this scenario with a Style Selector (already used for background coloration) :

<styleSelectors:ConditionalStyleSelector.Level1Style>
     <Style TargetType="telerik:TreeListViewRow">
          <Setter Property="Background" Value="#6699FF" />
          <Setter Property="IsExpanded" Value="{Binding Path=IsExpandedLevel1, RelativeSource={RelativeSource AncestorType={x:Type UserControl}}, Mode=TwoWay}" />
     </Style>
</styleSelectors:ConditionalStyleSelector.Level1Style>

However, when the user collapses one "level 2" line (for example) all "level 2" lines are collasped.
So we've changed the binding mode to "OneWay" :

<Setter Property="IsExpanded" Value="{Binding Path=IsExpandedLevel1, RelativeSource={RelativeSource AncestorType={x:Type UserControl}}, Mode=OneWay}" /> 

However, with mode "OneWay" it doesn't work ...

Any idea ? Or sample code to do this ?

Hi,

I hit the captioned issue that Drop Down of RadComboBox is Going to the Top Left Corner of the Screen.
It's does not happen all the time, but sometimes it does happen.

Is there any way to solve this?

Thanks

I'm evalulating Rad Charts as a possible component for my company and seem to have hit a wall.  Is it possible to have a bar chart, with positive and negative values on the same series and have the x-axis held at zero?  This would be very common in the financial world for say a performance chart.  Some bars go up, some bars go down depending on positive and negative performance buckets.  Am I correct in thinking the product does not currently support this?  

Many thanks,

Hi!

Please advice me on how can I customize the weekinterval so that it starts from Wednesday of a week and to end to Tuesday the next week (in my company the operational weeks are formed this way).
I have a table in which these weeks are kept.
If there'e a way I can bind TimeBar to this table, I will be glad to receive some help.

I attached a capture with the intervals and the selection made using my weeks table (you will see selection slightly shifted to capture those mentioned above)

Thank you in advance!

Hi,

I am having an issue with styling MapPolygons. I am able to style some settings such as the tooltip but am unsuccessful in styling other aspects like the border.

What I am trying to do is apply an Effect to a MapPolygon when the mouse is over it. Below is a Xaml snippet of my style, which doesn't work with or without the trigger. 


Applying a BorderBrush in the style doesn't work either. Is there something I am missing?

Thanks in advance.

Hello,

I am using WPF Controls version 2009.2.904.35.

First issue: I have a GridView control inside a TabItem. Whenever the application loads, if I expand the rows of the GridView control, the expansion works and the child rows are displayed. However, if I first click trough the TabItems and come back to expand the Grid rows, then the expansion works but the child rows are not shown. If I have expanded the rows at least once before I tab through, the child rows continue to be displayed even after I have visited other tabItems; the problem seems to happen only when I tab through before ever expanding any rows. One more thing, if I expand let's say 3 rows out of 5 in the grid, then tab through, then come back to expand the other 2 rows, those 2 rows' children won't be shown, but the children of the other 3 pre-expanded rows do continue to show. If I sort or filter the grid, then the rows reappear.

Second issue: If I position the cursor in between two columns to drag and size, the sizing of the column jumps around, and i can make it smaller but not bigger; also, if I stop dragging (release the mouse button), the column sizing continues to happen while I move my mouse. This happens in the same grid that's having the first issue. I have another grid in another tabItem and that one does not have the sizing issue; it also does not have child rows so I don't know if it would be the same problem.

Thanks,
Laura
