Is there a way to find out if the RadListBox.SelectionChanged event was triggered by user input (mouse click, touch, tabbing, keyboard input...) vs programmatically (by setting datacontext, binding, or  setting RadListBox.SelectedItem in code behind)?

Hi,

Can anyone help me with this problem. Please look here:

http://prntscr.com/m4t10v

The code of my GridView:

<telerik:RadGridView x:Name="GV_ProjectTerms" AutoGenerateColumns="False" Margin="10" RowIndicatorVisibility="Collapsed" ShowSearchPanel="False" CanUserFreezeColumns="False" CanUserReorderColumns="False" DragElementAction="None" IsFilteringAllowed="False" ShowGroupPanel="False">

I'm using 2017.3.1018.45 on 64-bit Windows 10 and Visual Studio 2017.

My application has a single chart view. I can change the data that is displaying. The DataContext changes out from under the view. When the DataContextChanged message arrives, I:

   1. save the current pan/zoom settings for the chart.

   2. clear all series.

   3. generate all series for the new data context

   4. restore the pan/zoom settings that were saved from the last time this data was displayed.

Except that it doesn't work at all. I have tried saving and restoring: Zoom, PanOffset, Horizontal/Vertical-ZoomRange-Start/End.

At first, I tried just saving/restoring Zoom and PanOffset. I could successfully set the Zoom, but the PanOffset was always (0,0) after the set.

I have tried invoking my restore operation on the dispatcher during Idle, so it should be done after everything has been complete.

Any ideas?

Hello,

Is there a way of customizing the appointment stack behavior when 2 or more items are overlapping on the timeline view?

Currently, the longest appointment will appear on top of the stack.

I would like to change this behavior so that the order of the stack is not calculated based on the length of the appointment but rather on a custom attribute or by the order in which the appointments are added.

Hello,

I have read the post on modifying RadChart Candlestick to display the median and therefore be a Box Plot / Box Whisker. http://docs.telerik.com/devtools/wpf/controls/radchart/how-to/howto-create-scatter-errorbars-and-boxplot-series

I would like to achieve this same effect using RadChartView, as I would like the implicit styles that ChartView provide over Chart. 

Please could you provide guidance on how I should go about adding a median line to the candlesticks in RadChartView 

Many thanks in advance.

Finally upgrading my controls..

How in the 'world' do I convert my Schedule to ScheduleView?

Hi,

I want my QueryableCollectionView Filter on event which invoke this function in my mainViewModel. Under is my attempt to filter this.

        private async Task OnContractGroupSelectionChanged()
        {
            this.ViewModelCategory.ViewModelCategory= new QueryableCollectionView(this.ViewModelCategory.CategoryData.Where(c => c.ID== this.SectionViewModle.ID));

        }

As you can see, I'm "newing" / creating a new instance of the QueryableCollectionView each time I choose a section in a grid.

How can I filter the QueryableCollectionView to only show items which is equal to the SectionID without having to new up an instance of the QueryableCollectionView? I can only choose one section at once, which means each time I choose a section, the QueryableCollectionView will only show the items with the same ID as the section.  I tried to add a FilterDescriptor in my MainViewModel which should update QueryableCollectionView  in my ViewModelCategory, but my program just hangs up when I try to do that.

Hi,

Is there any way of changing the background color on a RadDropDownButton when IsOpen = true, without needing to update the template?
