Hello,

I have a problem with the ScheduleViewDragDropBehavior class.
I want to be able to drop anything in my RadScheduleView, in an empty slot OR in an appointment.

Here is my dragDropBehavior class :

public class CPlanningTelerikDragDropBehavior : Telerik.Windows.Controls.ScheduleViewDragDropBehavior

{

public override void Drop(DragDropState state)

{/*Drop code*/

base.Drop(state);

}

But i don't know how to determine if the destination is an appointment or an empty slot.

Is there any way to do that ?

Regards,
Philippe.

Paste Plain Text

Does the RadRichTextBox support a 'paste plain text' mode?

If a user wants to paste in text that is formatted as a table, I would like it to just paste the data in the tables, becuase our reporting technology cannot handle html tables.

Any ideas if this can be done? I don't see anything in the Demos about special paste functions

RadRichTextbox in RadDiagramShape

Hello,

I have created a contentTemplate and an editTemplate for my control which inherits from RadDiagramShape. All works well with the other controls, but once I click on the RadRichTextbox in the editTemplate, the control switches back to the contentTemplate. So it is impossible to edit the text of the RadRichTextbox during runtime.

To make it more clear:
diagramItem -> editmode -> mouse click on the RadRichTextbox -> diagramitem immediately goes out of edit mode.

The RadRichTextbox has not been modified, and the control doesn't have any special events. All buttons, the watermarkTextbox and the normal Textbox work as they should.

Am I missing something or is the functionality not yet implemented in the RadDiagram component?

Regards,
James

Direction with SlideAndZoomTransition

Hi,
I have a problem with RadtransitionControl:
I set the transition property in the XAML as :

SlideAndZoomTransition

MinAlpha="1.0" MinZoom="1.0" StartSlideAt="0.2" LayoutAnimation="Animated" SlideDirection="LeftToRight"

My goal is to change the slideDirection at runtime from LeftToRight to RightToLeft, but I can' t access the RadTransitionControl object.

this is the xaml of my project:

Legend Customization

Hi,
I want to Manipulate the "Legend Label" to have different FieldName at run time on the basis of selection of Radio Button which would be either "Value" or "Percent".

As, such in case of Value it would be:-
<telerik:ItemMapping DataPointMember="LegendLabel" FieldName="ChartLegendValue"/>
and in case of "Percent" it would be:-
<telerik:ItemMapping DataPointMember="LegendLabel" FieldName="ChartLegendPercent"/>

How can i achieve this functionality ?
Can i use a data trigger / style or some other way?

Thanks in advance.

Zooming RadChart using MVVM

Hi,

I am using RadTreeView on the left side of the screen and showing relative data in RadChart on the right of the screen. I am using MVVM design pattern (WPF), but facing few problems (as mentioned below) while zooming chart data.

1. I am NOT able to bind values for RangeEnd and RangeStart with MVVM property for zooming my chart data. My XAML code looks like:
<telerik:ChartDefaultView.ChartArea>
<telerik:ChartArea Loaded="ChartArea_Loaded">
<telerik:ChartArea.ZoomScrollSettingsY>
<telerik:ZoomScrollSettings />
</telerik:ChartArea.ZoomScrollSettingsY>
<telerik:ChartArea.ZoomScrollSettingsX>
<telerik:ZoomScrollSettings MinZoomRange="0.01" RangeEnd="{Binding ChartRangeEnd, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" RangeStart="{Binding ChartRangeStart, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" ScrollMode="ScrollAndZoom" />
</telerik:ChartArea.ZoomScrollSettingsX>
<telerik:ChartArea.AxisX>
<telerik:AxisX IsDateTime="True"
AutoRange="True"
Step="1"
LabelStep="1"
DefaultLabelFormat="dd-MMM HH:mm"
LabelRotationAngle="30" StripLinesVisibility="Visible">
<telerik:AxisX.AxisStyles>
<telerik:AxisStyles RenderOptions.ClearTypeHint="Enabled" />
</telerik:AxisX.AxisStyles>
</telerik:AxisX>
</telerik:ChartArea.AxisX>
</telerik:ChartArea>
</telerik:ChartDefaultView.ChartArea>

The properties definition in ViewModel is:
double _chartRangeEnd;
public double ChartRangeEnd
{
get { return _chartRangeEnd; }
set
{
_chartRangeEnd = value;
OnPropertyChanged("ChartRangeEnd");
}
}

double _chartRangeStart;
public double ChartRangeStart
{
get { return _chartRangeStart; }
set
{
_chartRangeStart = value;
OnPropertyChanged("ChartRangeStart");
}
}

2. Zooming only works when I change RangeStart and RangeStart value pragmatically (in code behind on ChartArea_Loaded event), as shown below:
private void ChartArea_Loaded(object sender, RoutedEventArgs e)
{
this.radChart.DefaultView.ChartArea.ZoomScrollSettingsX.ScrollMode = ScrollMode.None;
this.radChart.DefaultView.ChartArea.ZoomScrollSettingsX.RangeEnd = _viewModel.ChartRangeEnd;
this.radChart.DefaultView.ChartArea.ZoomScrollSettingsX.RangeStart = _viewModel.ChartRangeStart;
this.radChart.DefaultView.ChartArea.ZoomScrollSettingsX.ScrollMode = ScrollMode.ScrollAndZoom;
}
Moreover if I remove top code line (this.radChart.DefaultView.ChartArea.ZoomScrollSettingsX.ScrollMode = ScrollMode.None;) then slider stretches 100% rather then getting within the limit of RangeStart and RangeEnd values.

The problem which I am facing while using code behind approach (using ChartArea_Loaded) is that when I click on any other node (after selecting first node) in the RadTreeView then RangeStart and RangeEnd values are not getting refreshed (as ChartArea_Loaded event is called only at the starting when Chart is loaded for the first time).

I am willing and hoping to resolve this problem by using MVVM.

Any help will be highly appreciated.

Thank you,
Moon
