I'm re-visiting our previous approach to create an arrow annotation, as our current one is clunky - a line with a shape appended to the end of it to emulate an arrow. It doesn't scale well with zooming in and out and our QA folks are asking for a better implementation.

Is there any add-on widget to achieve an arrow annotation in a RadCartesianChart ?

Is there a newer Chart that has arrow annotations built in ?

Thanks,

Barry

Filter icon doesn't appear on derived classes

I have a project which is using a base class (called Job) and two derived classes (Hire & Sales) - which share a lot of properties. When I add a string property to Hire and bind to that column in a gridview - the filtering icon doesn't appear above the column, however it works fine on when I bind to the base class - I've read that perhaps this is because it can't determine the datatype, but it is just a string.

This is a xaml example of two columns, next to each other, the first column displays the filter icon (SiteLocation is held within base class), the second column (SiteLocation1 held in Hire class) doesn't - they both show the correct data.

<telerik:GridViewDataColumn Header="Location" UniqueName="Location" DataMemberBinding="{Binding ScheduleItemJob.SiteLocation}" HeaderCellStyle="{StaticResource GridViewHeaderCellStyle}" IsReadOnly="True" CellStyle="{StaticResource GridViewCellStyle}"/>

<telerik:GridViewDataColumn Header="Location1" UniqueName="Location1" DataMemberBinding="{Binding ScheduleItemJob.SiteLocation1}" HeaderCellStyle="{StaticResource GridViewHeaderCellStyle}" IsReadOnly="True" CellStyle="{StaticResource GridViewCellStyle}"/>

How to prevent move a child shape of a RadDiagramContainerShape?

I'm trying to disable moving a child shape of a RadDiagramContainerShape by override DraggingService as below:

public class MyDragging : DraggingService

{

private readonly RadDiagram diagram;

public MyDragging(RadDiagram graph)

: base(graph as IGraphInternal)

{

this.diagram = graph;

}

public override void Drag(Point newPoint)

{

if (this.DraggingModels.FirstOrDefault().ParentContainer != null)

{

return;

}

else

{

base.Drag(newPoint);

}

It does make the child shape immovable. However, after I dragged the child shape, it will be removed from the parent container shape. (subShape.ParentContainer will be null). Then, when I drag the child shape again, it can be moved.

How to fix this issue?

IsHidden binding not showing Pane

I'm setting the style of my RadPane just like the 'VisualStudio' example:

<Style TargetType="telerik:RadPane" BasedOn="{StaticResource RadPaneStyle}">

<Setter Property="CanDockInDocumentHost" Value="False" />

<Setter Property="Header" Value="{Binding Header}" />

<Setter Property="IsHidden" Value="{Binding IsHidden, Mode=TwoWay}" />

</Style>

<Style TargetType="telerik:RadDocumentPane" BasedOn="{StaticResource RadPaneStyle}">

<Setter Property="Header" Value="{Binding Header}" />

<Setter Property="IsHidden" Value="{Binding IsHidden, Mode=TwoWay}" />

</Style>

My ViewModel has the IsHidden property, and is notifying fine. Removing the panels works. However, 'unhiding' them fails.

protected override RadPane CreatePaneForItem(object item)

{

var viewModel = item as IDockPane;

if (viewModel == null) return base.CreatePaneForItem(item);

var pane = viewModel.PaneType == PaneType.DocumentPane ? new RadDocumentPane() : new RadPane();

pane.DataContext = item;

RadDocking.SetSerializationTag(pane, viewModel.Header);

pane.Content = new TextBlock { Text = "Test" };

return pane;

}

After some searching these forums, it seems an issue with the binding not updating because it's removed from the visual tree? If so, is there any alternatives? How is the Visual Studio example getting around this? I can find no other code that attempts to restore the hidden panes - but maybe I'm missing it.

I tried simply listening for the IsHidden property change:

viewModel.PropertyChanged += (sender, args) =>

{

pane.IsHidden = viewModel.IsHidden;

};

And this half works. The first time it does nothing, but the second time you 'cycle' the IsHidden property (say with a checkbox) it appears again! Except the tabs are missing their headers.

The DataContext is set fine, and if I go in and press 'reset' on the binding in the Visual Studio live property editor it refreshes just fine to the right header.

Losing focus clears Text when IsFilteringEnabled="True"

Hello,

I want to use the Combobox with IsFilteringEnabled="True" to allow users to select items from a combobox.
However users should also be able to enter new things, that are not (yet) available in the list. Kind of like a recently used list.

When I enable filtering the combobox always clears itself when the focus is lost, thus my users can never enter anything new.
Is there a way to turn this off?
Or is there any other way I can do this?

Thanks!

Regards,
Peter

RadGridView Scroll working very slowly in new telerik version

Hi Team,

I was using Q2 2010 SP2 - 2010.2.924.40 version and in that I was using RadGridview ScrollIntoView method to scroll to the last record.

It was only taking around 30 seconds for 1000 records

Now we updated to latest version 2018.2.515.45 version now with same code it is taking more than 1 minutes to autoscroll to last record.

Xaml Code:

<telerik:RadGridView Grid.Row="1" Grid.Column="0" Name="EmployeeSheetGrid" Height="300" CanUserInsertRows="False" ItemsSource="{Binding Path=WorkItems}" ColumnWidth="*" AutoGenerateColumns="False" ScrollMode="RealTime" CanUserReorderColumns="False" DataLoadMode="Synchronous" CanUserSortColumns="False" CanUserFreezeColumns="False" ShowGroupPanel="False" IsReadOnly="True" >

Xaml.cs record.

public class Employee { public int EmpId { get; set; } public string Name { get; set; } public string Address { get; set; } public string State { get; set; } public String Country { get; set; } public DateTime CurrentDate { get; set; } }

EmployeeList having 1000 records

employeeList.OrderBy(i => i.EmpId).ToList().ForEach(s => { EmployeeSheetGrid.ScrollIntoView(s); });

Please provide solution for the issue.

Thanks
