How can I change the mouseover of the contextmenu when I add a checkbox? I can easily change radmenuitems but haven't found a way yet to change the checkbox' team. I did check in the contextmenu itself for teams but nothing exists there whatsoever about mouseover themes.

Is it possible to draw in the charting area? For example, I would like to draw a red line, perhaps, through the chart at the Y-Value of 60 (assuming this chart has one Y-Axis). Or perhaps I would like to shade the area above the Y-Value of 100 red. I know I can do the shading by setting the background brush, but its critical to know where the Y-Value of 60 or 100 is in these examples. Is this possible with RadChart?

Hi,
Because this supports the INotifyCollectionChanged event, the RadChart attaches to this event.
I am binding the following list of dataseries to a RadChart ItemsSource to get dynamic updates:
| var chartSeries = new RadHierarchicalObservableCollection<ObservableCollection<AnalogDataPoint>>(); |
However, if I later close my window and set ItemsSource to null, the event handler is not removed. Therefore, the whole RadChart is still connected to the data and is not collected. (Actually, the whole view is retained because the RadChart keeps references to its parent...).
Please correct this to remove any event handler when the item source changes.
Kind regards

Hi All
I have tried all manor of solutions to this problem.
Basically I have an attributes table which contains a type. this type is bound to a GridViewComboBoxColumn. when the selection in this column is changed, it needs to set the isvisible value of other columns in the same grid row.
So, in the usual way, I have created a converter such as this:
in the xaml, the converter is called like this:
The value for the cell is updated when the attribute_id is changed, but the visibility converter is never called.
the second option that I have tried is to use the GridViewdataColumn element, such as this:
gridAttributes_attributeType1 is the name of the GridViewComboBoxColumn.
This also does not call the converter as I suspect that the path SelectedValue does not exist in a GridViewComboBoxColumn.
The solution does call the converter however, if I bind it to a combo outside of the gridview..
Is there any solution to this problem.
Regards
Nick

| return false; |
| } |
| } |

Hi,
i want to use checkboxes in several columns and therefore my code - for 1 gridview column - looks like this:
____________________________________________________________________
<telerik:GridViewDataColumn x:Name="colResultNT" Header="Result NT" IsReadOnly="True" IsEnabled="False" DataMemberBinding="{Binding ResultNt}">
</telerik:GridViewDataColumn>
<telerik:GridViewDataColumn x:Name="colReview" Header="Review Needed?" DataMemberBinding="{Binding IsReviewNeeded}">
<telerik:GridViewDataColumn.CellStyle>
<Style TargetType="GridView:GridViewCell">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="GridView:GridViewCell">
<CheckBox Margin="5,0,0,0"
HorizontalAlignment="Left"
VerticalAlignment="Center"
IsChecked="{Binding IsReviewNeeded, Mode=TwoWay}" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</telerik:GridViewDataColumn.CellStyle>
</telerik:GridViewDataColumn>
____________________________________________________________________
This code works fine, but actually the vertical grid line on the right sight disappered (see attached screenshot). Any ideas why? How can i get it back?
Thx in advance

Hello,
I have a difficulty about binding a list of type Binding<T> list to Grid. The binding is working fine, but grouping is not working on the side of XAML.
| <Telerik:RadGridView.GroupDescriptors> |
| <data:GroupDescriptor Member="CodeOrganizationType"> |
| <data:GroupDescriptor.AggregateFunctions> |
| <data:CountFunction Caption="Count:" /> |
| </data:GroupDescriptor.AggregateFunctions> |
| </data:GroupDescriptor> |
| </Telerik:RadGridView.GroupDescriptors> |
grouping via code works fine, XAML is not working.
Am I doing something wrong ?
Telerik Version : 2010.1.0422.35

I'm thinking of a hybrid control that would allow the user to select a year, a month in a year a date, or collection of dates.
My scenario is that we have an application that sits on top of an Analysis Services Cube. In that cube we have a date dimension and you can use that dimension to slice data by year or month or date or set of dates.
My current implementation involves a TreeView - where the user selects year or month and then uses the calendar to select a date (screenshot). This allows then to select the Year by selecting that TreeNode, the month, or a specific date in the month.
However, I don't really love this implementation. I like the contextual representation and ease of mouse gesture movement in the RadCalendar control. Particularly, drilling up and down to through the views (Decade View, Year View). I have this nagging feeling that I could customize the control in some way so that I could get it to work for my uses instead. For example in the Year View, instead of clicking the month drilling down to the Month View - change it so clicking the Month selects the month instead - and instead change the drilldown to be attached to a linkbutton on the month text abbreviation (screenshot).
Would something like that be possible?
If so, I'm not sure how to go about doing that. I tried loading up Expression Blend 3 and dragging the RadControl into it, thinking it's got to be somewhere in the template/style area that I do this but I get an error 'Cannot locate resource 'themes/genericvista.xaml'' (screenshot). Admittedly by Blend experience is terrible but I'd like to work on that.
Am I on the right track?
