Spline series

Hello,

I'm currently evaluation the chart control and tried to draw a spline line. The result looks odd (see attached screenshot). I would expect a line as shown in the second attachment.

These are the point of spline:

this.DataContext = new List<ChartData>()
{
new ChartData { XVal = 1, YVal = 0.2 },
new ChartData { XVal = 2, YVal = 0.259 },
new ChartData { XVal = 15, YVal = 2.884 },
new ChartData { XVal = 25, YVal = 5.15 },
new ChartData { XVal = 40.3, YVal = 8.73 },
new ChartData { XVal = 50, YVal = 9.9 },
};

It seems there is a problem with the slope. Is there a way to set the start slope?

Best Regards

Olaf

Bar chart label far away from axis

Hi, I am using telerik:RadCartesianChart in my UI. But I can't control the alignment of the vertical labels.

My code looks like this:

================================================================================================

<telerik:RadCartesianChart x:Name="BarChart" Grid.Row="1"
                                       VerticalAlignment="Stretch"
                                       HorizontalAlignment="Stretch">
                <telerik:RadCartesianChart.HorizontalAxis>
                    <telerik:CategoricalAxis GapLength="0.4"
                                             LabelFitMode="Rotate"
                                             ShowLabels="True"
                                             SmartLabelsMode="SmartStep"
                                             LabelStyle="{StaticResource BarLabelTextStyle}"
                                             PlotMode="OnTicksPadded" />
                </telerik:RadCartesianChart.HorizontalAxis>
                <telerik:RadCartesianChart.VerticalAxis>
                    <telerik:LinearAxis Maximum="{Binding MaxCount}"
                                        Minimum="{Binding MinCount}"
                                        ShowLabels="True"
                                        LabelStyle="{StaticResource BarLabelTextStyle}" />
                </telerik:RadCartesianChart.VerticalAxis>
                <telerik:RadCartesianChart.Grid>
                    <telerik:CartesianChartGrid MajorLinesVisibility="Y" />
                </telerik:RadCartesianChart.Grid>
                <telerik:BarSeries CategoryBinding="Name"
                                   ValueBinding="Proportion"

                                   ShowLabels="{Binding LabelEnabled}"
                                   CombineMode="Cluster"
                                   IsHitTestVisible="True">
                    <telerik:BarSeries.PointTemplate>
                        <DataTemplate>
                            <Border
                                Background="{Binding DataItem, Converter={StaticResource SliceToBarBrushConverter}}"
                                MouseEnter="BarElement_MouseEnter"
                                MouseLeave="BarElement_MouseLeave" />
                        </DataTemplate>
                    </telerik:BarSeries.PointTemplate>
                </telerik:BarSeries>
                <telerik:RadCartesianChart.Behaviors>
                    <telerik:ChartTrackBallBehavior />
                    <telerik:ChartPanAndZoomBehavior x:Name="ZoomPanBehavior" ZoomMode="None" PanMode="None"
                                                     DragMode="Pan" />
                    <telerik:ChartSelectionBehavior DataPointSelectionMode="Multiple" HitTestMargin="2"
                                                    SelectionChanged="BarChartSelectionBehavior_SelectionChanged" />
                </telerik:RadCartesianChart.Behaviors>
            </telerik:RadCartesianChart>

================================================================================================

Changing the BarLabelTextStyle HorizontalAlignment is not affecting anything for bar labels.

The result looks like from attachment. You can see that the first bar chart's vertical labels are too far away from axis. And the second bar chart's labels are too close to the first bar chart, comparing to it's own axis.

Is there something I can do here?

Thanks.

Remove duplicate members from SimpleFilterMemberComboBox

I am trying to find a solution to display only unique members in the rad data filter. For ex I have a class Employee with 3 properties Name, Age, Address. User clicks on the + sign and in the first filter editor selects Name. Then user adds another filter editor, in this one i do not want to display Name property similarly if user selects age in the second one, I want to remove age option from the first filter and not have that in other editors.

I am reading some posts about SimpleFilterMemberComboBox and how to manipulate the available members items, but that looks very compilcated, Just wondering if there is some easy option for this.

Data from RadDataForm doesn't fall into property of object to which RadDataForm is bound.

Hi! I try to use RadDataForm in my WPF MVVM Prism 6 application. Since I began to use this control I've collided with some problems - data from form is not passed into properies of the object to which RadDataForm is bound. Below is the class to object of which RadDataForm is bound:

public class Group : IEditableObject

{

struct GroupData

{

internal string name;

}

private GroupData _newGroupData;

private GroupData _backupGroupData;

private bool _isEditMode = false;

public Group()

{

this._newGroupData = new GroupData();

this._newGroupData.name = string.Empty;

}

public string Name

{

get { return this._newGroupData.name; }

set { this._newGroupData.name = value; }

}

public void BeginEdit()

{

if(!this._isEditMode)

{

this._backupGroupData = this._newGroupData;

this._isEditMode = true;

}

public void CancelEdit()

{

if (this._isEditMode)

{

this._newGroupData = this._backupGroupData;

this._isEditMode = false;

}

public void EndEdit()

{

if (this._isEditMode)

{

this._backupGroupData = new GroupData();

this._isEditMode = false;

}

public override string ToString()

{

StringWriter stringWriter = new StringWriter();

stringWriter.Write(this.Name);

return stringWriter.ToString();

}

Then in view model:

private Group _profileElementsGroup;

public Group ProfileElementsGroup

{

get { return this._profileElementsGroup; }

set { this.SetProperty(ref this._profileElementsGroup, value); }

}

Then in XAML of view:

<Grid.Resources>

<DataTemplate x:Key="GroupTemplate">

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition/>

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>

<RowDefinition/>

</Grid.RowDefinitions>

<telerik:DataFormDataField Grid.Row="0" Label="GroupName" DataMemberBinding="{Binding ProfileElementsGroup.Name, Mode=TwoWay}"/>

</Grid>

</DataTemplate>

</Grid.Resources>

<telerik:RadDataForm HorizontalAlignment="Center" VerticalAlignment="Top"

AutoGenerateFields="False" Header="Add Element Group of Profile of Device" ReadOnlyTemplate="{StaticResource GroupTemplate}"

EditTemplate="{StaticResource GroupTemplate}" CurrentItem="{Binding ProfileElementsGroup}">

<telerik:EventToCommandBehavior.EventBindings>

<telerik:EventBinding

Command="{Binding HandleEndEditNewProfileElementsGroupCommand}"

EventName="EditEnded"

PassEventArgsToCommand="True"/>

</telerik:EventToCommandBehavior.EventBindings>

</telerik:RadDataForm>

When I printing in my RadDataForm in Name field I set breakpoint in C# code of Name property and this breakpoint is not activated. So data from RadDataForm doesn't fall into ProfileElementsGroup.Name property. What I do wrong? Please help.

Custom Pins

Can anyone point me to an example of how to place custom pins on a map? I've seen demos and other examples that do exactly what I'm looking for but none of them give any code or explanation of how to do the pins.

I've attached a screen shot of what I'm looking for.

Thanks in advance

RadComboBox SelectionChanged Text Property Not Set Properly

When processing the SelectionChanged event for a RadComboBox, the Text property of the control is not yet set with the new text value. For example, we add a RadComboBox with the SelectionChanged event set to the following OnSelectionChanged.

private void OnSelectionChanged(object sender, SelectionChangedEventArgs e)

{

RadComboBox cb = sender as RadComboBox;

Trace.TraceInformation("cb.Text = {0}", cb.Text);

}

When we start typing in the Combo Box, the displayed text is always the Text value before the latest character. So,l when we type 1, cb.Text is null, when we type 2, the combo box displays "12", but cb.Text is 1.

How can we see the current value of the text box when the selection is changed?

enter "-0" into RadDatePicker will crash the application

Hi,

We are migrating some existing systems to WPF and when I try "-0" with the RadDatePicker, The whole application crashed immediately without further error message etc. Is this a bug of the control? Would this be fixed in the next patch or release?

PS. We are testing with version Q3 2009 SP1 and "-0" is one of the shortcut keys of our existing system.

Thanks,
John

ApplicationMenu not closing with KeyTip

Hi,

I am running the following xaml:

<Grid><br> <telerik:RadRibbonView telerik:KeyTipService.IsKeyTipsEnabled="True"><br> <telerik:RadRibbonView.ApplicationMenu><br> <telerik:ApplicationMenu telerik:KeyTipService.AccessText="F"><br> <telerik:RadRibbonButton Content="New" telerik:KeyTipService.AltAccessText="N"/><br> </telerik:ApplicationMenu><br> </telerik:RadRibbonView.ApplicationMenu><br> </telerik:RadRibbonView><br> </Grid><br>

When I do "Alt+F", it opens the main menu like it should, but then if I press "N" alone, it clicks the button but does not close the application menu (and the access key disappears too). If I press "Alt+N", it closes the application menu promptly. My question is how do I close the application menu on just "N" alone?

Any ideas?

Best
