How do I go about animating multiple series using utils:ChartAnimationUtilities.CartesianAnimation="Rise"? Below is my code, I have tried multiple ways and none work. Thanks.

<telerik:ChartSeriesProvider  Source="{Binding Data, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:ParameterTraceControl}}}">             
                    <telerik:ChartSeriesProvider.SeriesDescriptors>
                        
                        <telerik:CategoricalSeriesDescriptor CategoryPath="ReadTime" 
                                                        ValuePath="Value" 
                                                        ItemsSourcePath="Items">
                            
                            <telerik:CategoricalSeriesDescriptor.Style>
                                <Style TargetType="telerik:LineSeries" BasedOn="{StaticResource LineSeriesStyle}">
                                    <Setter Property="StrokeThickness" Value="{Binding SelectedStrokeThickness, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type View:MainWindow}}}" />
                                    <Setter Property="LegendSettings">
                                        <Setter.Value>
                                            <telerik:SeriesLegendSettings Title="{Binding SeriesName}" />
                                        </Setter.Value>
                                    </Setter>
                                  
                                </Style>
                            </telerik:CategoricalSeriesDescriptor.Style>
                            
                        </telerik:CategoricalSeriesDescriptor>

                </telerik:ChartSeriesProvider>

Hello,

When user enter a text in TrackChange mode, text divides by minutes. For example, if user begin write "This is a" at 16:09, and completes write " test for Telerik" at 16:10, Track Change detects it as 2 changes made in 16:09 and 16:10. Is it a feature, or is it a bug? :)

Is it possible to register a change when user completes write a text, at least on FocusLost action. Or may be other solution? I want to view "This is a test for Telerik" as one change, made in 16:10.

Thank you.

Hi,

please can you advice me how to achieve range selection in RadCartesianChart which has dynamic number of series?
For chart itself I used ChartSeriesProvider as descripted in your tutorial but now I stuck with range selection.

Many thanks!

I have a RadCartesianChart that I am dynamically adding linear series to. I set the minimum and maximum for the y-axis but sometimes it doesn't show a tick for the maximum value at the top of the y-axis. How can I get the graph to always display a tick for the maximum value?

Thanks

can i use RecurrenceTask in array?

Hello,

I've based my code on the RecurringTask example project.
I was able to get my desired visual result but I've now discovered an action that causes my application to crash.
This makes it pretty much unusable, so I need to find a solution or at least a way to catch the exception and prevent it from crashing.

I've been able to pinpoint the cause of my problem, but have been unable to solve this by myself.

Let me start by describing my current situation/environment.

In the RecurringTask_WPF example project if you collapse the "Recurrence Series" (the parent tree node) then you can see all the child recurring tasks next to each other.
When you click on one of the events, so for example: "Recurrence 1"  block (in the TimeRuler Part of the RadGanttView), then this specific recurring task gets selected. This causes the tree node to be expanded automatically and the selected task/event becomes highlighted.

This behaviour works perfectly as intended and I wish to keep it like that exactly.
However once you nest recurring tasks into one extra level of hierarchy, which is on my requirements, an exception is thrown and the program stops working.

First I'll give you the code that changes the example project in order to recreate the problem. (This should also help with explaining the exact problem)
You should replace the GetTasks() method of the ViewModel.cs with the code below:

When you run the example with these code changes, you should see that the "Recurrence 3" task now is moved into a new "Recurrence Series2".
This new series is also a child of the original "Recurrence Series1".
So when then all the nodes become collapsed you can still see all child recurrences next to each other.
If you now click on the "Recurrence 3" event (in the TimeRuler Part of the RadGanttView) the application will throw a System.NullReferenceException.

This is the StackTrace  (it is in Dutch, but I believe it should still be readable):

Here are some other observations that might help you find the exact cause of this problem:

• If you were to click any other recurring task then the program would keep working as expected.
• If only the top note is collapsed and the child "Recurrence Series2" stays expanded, then the behaviour also keeps working as expected

It would seem that the problem only occurs when nested nodes are collapsed and a child task of a hierarchy that is at least 2 levels deep gets selected.

Now I would just like to find a way to stop my program from crashing.
I've tried handling click events in order to prevent the user from clicking on events in the TimeRuler Part of the RadGanttView, but I wasn't able to figure out how to and I would also still like to keep the behaviour of the automatic expanding and selecting the specific task.

I've also tried to implement a click-command which showed me that the expanding actually works correctly and the exception only occurs afterwards.

Any help would be very much appreciated.

Hello,

I trying to move rows up or down depending on user selection from the Context Menu.

And for some reason (still trying to figure out), the IndexOf is returning -1.

Below are my XAML code =>

             <telerik:RadGridView x:Name="gridView1" Grid.Row ="1" AutoGenerateColumns="False" Margin="0,5,0,10" FontSize="12" Deleted="OnDeletedIO"

                                <MenuItem Header="MoveUp"  Click="MoveUp_click"/>
                            </ContextMenu>
                        </telerik:RadGridView.ContextMenu>

                        </telerik:RadGridView.Columns>
                  </telerik:RadGridView>

C# code =>

namespace MBM_WPF

            catch 
            {
                mbm1 = new MBM();
                mbmView = new MBM_view(mbm1, OnSettingChanged);
                BindMyData();
            }
        }

private void MoveUp_click(object sender, RoutedEventArgs e)
        {            
            //Get the clicked MenuItem
            var menuItem = (MenuItem)sender;
            
            //Get the ContextMenu to which the menuItem belongs
            var contextMenu = (ContextMenu)menuItem.Parent;            

            //Find the placementTarget
            var item = (RadGridView)contextMenu.PlacementTarget;
            
            int index = this.gridView1.Items.IndexOf(item.SelectedItem);

            this.gridView1.Items.Remove(item.SelectedItem);
           
            this.gridView1.Items.Insert(index - 1, item.SelectedItem);
            item.SelectedItem = item; 

            mbmView.IoListCleanUp();
            mbmView.AlarmsCleanUp();    

        }
     }
}

Please help.

Thank you!!
