I was not able to set custom appointment height and width at runtime So, I was used TimelineAppointmentsPresenter class and ResolveOverlappingAppointments method using possible to display manually height and width at runtime.But I was faced one problem our appointment data is 10,00,000 When I was  create new appointment and set only new appointment height and width set. then all other appointment height and width default set(Not  Consider when previously set).So,every time set all appointment height and width.So,how to set only current appointment height and width and all other appointment  are as it is ?

Because it's decrease performance.

----Code

 Protected Overrides Sub ResolveOverlappingAppointments(availableSize As SizeF)
        
Dim arrangedAppointments As New List(Of AppointmentElement)()
  
        AppointmentElements.AsEnumerable().Where(Function(e) e.Visibility <> ElementVisibility.Collapsed).
            All(Function(o)
                  
    End Sub

End Class

I am using a RadLiveTileElement. I want to put two custom user control and one LightVisualElement in it. I have written the following lines of code:

 

this.lteFrames1.ContentChangeInterval = 4000;
this.lteFrames1.TransitionType = ContentTransitionType.SlideUp;
this.lteFrames1.Text = "";
this.lteFrames1.TextImageRelation = TextImageRelation.Overlay;
this.lteFrames1.ForeColor = Color.Black;
this.lteFrames1.Row = 0;
this.lteFrames1.Column = 0;

RadHostItem host = new RadHostItem(new ucChartSalePerCompany()
{
Dock = DockStyle.Fill
});           
this.lteFrames1.Items.Add(host);

RadHostItem host2 = new RadHostItem(new ucChartSalePerMonth()
{
Dock = DockStyle.Fill
});

this.lteFrames1.Items.Add(host2);
this.lteFrames1.Items.Add(new LightVisualElement()
{
Padding = new Padding(4, 30, 0, 0),
       Font = new Font("Segoe UI Light", 12, GraphicsUnit.Point),
       ShouldHandleMouseInput = false,
       NotifyParentOnMouseInput = true,
       BackgroundImage = Properties.Resources.saleList2,
       BackgroundImageLayout = ImageLayout.Stretch,
       ForeColor = Color.Green,
       ZIndex = 10000
});

 

Everything is ok except the animation. The animation transition is ok only for the last item (LightVisualElement) that comes up inside of RadLiveTileElement and the other items (my user controls) come up from outside of RadLiveTileElement.

How can I solve this problem?

Thanks,

Hi,
if I add 2 FilterDescriptor with same propertyname, I get an exception:

An unhandled exception of type 'System.ArgumentException' occurred in mscorlib.dll
Additional information: Ein Element mit dem gleichen Schlüssel wurde bereits hinzugefügt.
(
An element with the same key has already been added.)

Stacktrace:

   bei System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
   bei System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
   bei Telerik.Data.Expressions.ExpressionContext.Add(String key, Object value)
   bei Telerik.WinControls.UI.RadTreeViewElement.EvalFilter(RadTreeNode node)
   bei Telerik.WinControls.UI.TreeNodeView.UpdateView()
   bei Telerik.WinControls.UI.RadTreeNodeCollection.Update()
   bei Telerik.WinControls.UI.RadTreeViewElement.UpdateNodes()
   bei Telerik.WinControls.UI.RadTreeViewElement.filterDescriptors_CollectionChanged(Object sender, NotifyCollectionChangedEventArgs e)
   bei Telerik.Collections.Generic.NotifyCollection`1.OnCollectionChanged(NotifyCollectionChangedEventArgs args)
...

Code:

    var fdc = new FilterDescriptorCollection();
fdc.Add(new FilterDescriptor("Time", FilterOperator.IsGreaterThanOrEqualTo, new DateTime(2017, 1, 1)));
fdc.Add(new FilterDescriptor("Time", FilterOperator.IsLessThanOrEqualTo, new DateTime(2017, 3, 31)));
fdc.Add(new FilterDescriptor("Location_Id", FilterOperator.IsEqualTo, 2));
this.radDataFilter1.FilterDescriptors.AddRange(fdc);

 

It works, if I calculate the Expressionstring:

this.radDataFilter1.Expression = fdc.Expression;

 

What is the correct way to initialize a Datafilter by code?

Peter

                        End With
                    End If

Is it possible to cancel a Drag and Drop Operation like on TreeView?
http://docs.telerik.com/devtools/winforms/treeview/drag-and-drop/cancel-a-drag-and-drop-operation

I'd like to impose some restrictions on drop operation based on from/destination rows.

Thank you.
