Hi Telerik Team.

The CandlestickSeries seems to have an odd behavior for negative values. The attached image shows a graph where the candlestick values should decrease linearly from left to right, but they stop at around y=0.

What is a workaround for this?

I use Telerik Version 2012.2.912.40, WPF

Code:

<telerik:RadCartesianChart>

<telerik:RadCartesianChart.VerticalAxis>

<telerik:LinearAxis/>

</telerik:RadCartesianChart.VerticalAxis>

<telerik:RadCartesianChart.HorizontalAxis>

<telerik:CategoricalAxis/>

</telerik:RadCartesianChart.HorizontalAxis>

<telerik:CandlestickSeries x:Name="Series0"

HighBinding="High"

OpenBinding="Open"

CloseBinding="Close"

LowBinding="Low"

CategoryBinding="X">

</telerik:CandlestickSeries>

</telerik:RadCartesianChart>

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

this.Loaded += new RoutedEventHandler(MainWindow_Loaded);

}

void MainWindow_Loaded(object sender, RoutedEventArgs e)

{

var chartData = new List<MyChartDataClass>();

for (int i = 0; i < 35; i++)

{

var cdc = new MyChartDataClass()

{

X = i,

High = 5 - i,

Open = 4 - i,

Close = 3 - i,

Low = 2 - i,

};

chartData.Add(cdc);

}

Series0.ItemsSource = chartData;

}

public class MyChartDataClass

{

public int X { get; set; }

public double Close { get; set; }

public double Low { get; set; }

public double Open { get; set; }

public double High { get; set; }

}

Hi everyone,

I would like to open, focus and select all text in editable RadComboBox when my wpf form is opened.

So I set following properties:

OpenDropDownOnFocus="True" SelectAllTextEvent="GotFocus"

and I call the Focus(); on form's constructor.

But the comboBox is closed with no selected text in it.

Could you help me what am I doing wrong?

Thank you for your replies.

Setting Pan and Scale

Using your pdfviewer control.
If I set IsInPanMode = "true" on the contol it doesn't seem to honor that setting. However if i have a toggle button that i bind to the FixedDocumentViewer.IsInPanMode property it seems to work.

I get the same effect with ScaleMode - except here : if i set it directly on the control it doesn't work, but I also can't seem to get FixedDocumentViewer.ScaleFactor binding to work on other controls like Slider etc.

Any hints at what I'm doing wrong?

Radribboncombobox - Type of the selected item is displayed instead of value in 2013.1.220.1050

When a list is bound to RadComboxBox, the selected item is showing the type instead of actual value.

<Controls:RadRibbonComboBox x:Name="namesCombo">

<Controls:RadRibbonComboBox.ItemTemplate>

<DataTemplate>

<Border Background="Transparent">

<TextBlock Text="{Binding Name}">

<UserControls:TooltipHelper.Tooltip>

<ToolTip Template="{StaticResource TextToolTipTemplate}" Content="{Binding Description}"/>

</UserControls:TooltipHelper.Tooltip>

</TextBlock>

</Border>

</DataTemplate>

</Controls:RadRibbonComboBox.ItemTemplate>

</Controls:RadRibbonComboBox>

private void SetWriteableTemplates(bool isUserAdmin)

{

if (Templates == null) return;

namesCombo.ItemsSource = Templates.Where(t => isUserAdmin || !t.IsSystem).ToList();

namesCombo.SelectedIndex = 0;

}

But the selected item will be the type of the list instead of actual value.

The value for Name wont be displayed in selected value.
for eg : The Name property contains certain values and its type is observable collection. Then the selected value will be displayed as that observablecollection

Z Order of Map object and whole InformationLayer

I have multiple InformationLayers inside my RadMap control, each of them showing different MapItems. The objects (MapItems) are bound via ItemsSource.

How can I bringt a MapItem to front?
It seems that there is no ZIndex Property. I managed it by moving an object to the end of the ItemsSource. Is there a better way?

How can I bring a whole InformationLayer to Front?
When moving an object to the end of ItemsSource like said above, it is still covered by MapItems which are part of a "higher" layer. Is there anything like good old "BringToFront()" for InformationLayer?

[Solved] How to conditional style a row of TreeViewList

Hello,

I have created a RadTreeViewList using mvvm pattern with a simple class named TreeItem:

public class TreeItem

{

private string title;

private ObservableCollection<TreeItem> items;

public string Title

{

get { return title; }

set { title = value; }

}

public ObservableCollection<TreeItem> Items

{

get { return items; }

set { items = value; }

}

public TreeItem()

{

}

public TreeItem(string ptitle)

{

this.Title = ptitle;

this.Items = new ObservableCollection<TreeItem>();

}

I manually create the object hierarchy and binded the control in code. I wanted to style the control as in the provided image, desired.png. However, what I was able to attained is shown in the image, result.png.

I have studied the Style & Templates sections of both RadTreeViewList and RadGridView, but none of those guides "show" what part of the control they affect. If it is possible, please provide an example of how to style each row based on either indent position, or how to augment the data class to accomplish my goal.

Thanks in advance.
