Binding radAreaSparkLine to dictionaries

Hello,

I am having some trouble binding a radAreaSparkLine to an ObseravbleCollection of dictionaries. I am trying to use a radTimeBar using the getting started1 video. The code I have is below. When I run parseResourceFile, the resourceItems collection is populated. However, when I create the radAreaSparkLine, no areaPoints are created, are nothing shows up in the timeBar. Does it look like I am doing anything incorrectly?

Thanks,
Eric

<telerik:RadTimeBar Grid.Row="2" x:Name="radTimeBar">

<telerik:RadTimeBar.Intervals>

<telerik:HourInterval />

<telerik:MinuteInterval/>

<telerik:SecondInterval/>

<telerik:MillisecondInterval/>

</telerik:RadTimeBar.Intervals>

</telerik:RadTimeBar>

class ResourceItem

{

public Dictionary<int, double> NumericalResourceValues

{

get { return numericalResourceValues ?? (numericalResourceValues = new Dictionary<int, double>()); }

}

public Dictionary<int, double> numericalResourceValues;

}

class Resource

public ObservableCollection<ResourceItem> ResourceItems { get; set; }

}

void populateTimeBar()

{

int

startTimeColumnIndex = 1;

int dataColumnIndex = 1;

var resourceParser = new ResourceParser();

Resource resource = resourceParser.PaserResourceFile(Constants.LogFilePath);

var rasl = new RadAreaSparkline

{

ItemsSource = resource.ResourceItems,

XValuePath = "NumericalResourceValues[" + startTimeColumnIndex + "]",

YValuePath = "NumericalResourceValues[" + dataColumnIndex + "]"

};

this.radTimeBar.Content = rasl;

this

.radTimeBar.DataContext = resource.ResourceItems;

}

sparkline DateTime for XValuePath

Hello,

How can I bind to a dateTime for the xvalues for the sparkline control? It gives me an argumentException if I try. It seems to want a double value for the xvalue.

Thanks,
Eric

first column, selected row indicator column

How do you hide the first column in the grid. It's the selected row indicator column. So when you select a cell in a row, the arrow indicator moves to that row. It's the column that shows up before you data columns are generated.

THanks

[Solved] DropShadowEffect

I can create RadContextMenu with a DropShadowEffect if I just show it in a Grid; however if I try and attach it to a Window.ContextMenu (or any other control) the shadow doesn't appear. I've tried all sorts of variations using Resource Styles and ResourceDictionaries, and nothing works. I'm including the MainWindow.xaml source and a screen shot showing the results.

<Window

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

x:Class="WpfApplication2.MainWindow"

x:Name="Window"

Title="MainWindow"

Width="640" Height="480"

>

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu ClickToOpen="True"

InheritDataContext="False">

<telerik:RadContextMenu.Effect>

<DropShadowEffect ShadowDepth="3" Opacity="0.445" RenderingBias="Quality"/>

</telerik:RadContextMenu.Effect>

<telerik:RadMenuItem Header="Copy" />

<telerik:RadMenuItem Header="Paste" />

<telerik:RadMenuItem Header="Cut" />

<telerik:RadMenuItem IsSeparator="True" />

<telerik:RadMenuItem Header="Select All" />

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

<Grid x:Name="LayoutRoot">

<telerik:RadContextMenu

Margin="105,53,247,147"

ClickToOpen="True"

InheritDataContext="False">

<telerik:RadContextMenu.Effect>

<DropShadowEffect ShadowDepth="3" Opacity="0.445" RenderingBias="Quality"/>

</telerik:RadContextMenu.Effect>

<telerik:RadMenuItem Header="Item 1">

<telerik:RadMenuItem Header="Sub Item 1"/>

<telerik:RadMenuItem Header="Sub Item 2"/>

</telerik:RadMenuItem>

<telerik:RadMenuItem Header="Item 2">

<telerik:RadMenuItem Header="Sub Item 3"/>

<telerik:RadMenuItem Header="Sub Item 4"/>

<telerik:RadMenuItem Header="Sub Item 5"/>

</telerik:RadMenuItem>

</telerik:RadContextMenu>

</Grid>

</Window>

What am I doing wrong?

Thanks in advance,
Steve

Selection Zooming issue

Hello,

I'm experiencing an issue with using the mouse selection zooming (where you select a rectangle to zoom in on). After a few successful zooms, an error is thrown (ArgumentException: Width and Height must be non-negative.) when trying to zoom in to fine detail. I assume this has something to do with rendering the pan/zoom bar, but I'm not certain.

I can catch the previewMouseUp event, but I'm not sure how to correctly check/handle this issue.

Any help/guidance would be appreciated.

Also, the interesting bit of the stacktrace from the exception:

at System.Windows.Size..ctor(Double width, Double height)
   at Telerik.Windows.Controls.ChartView.ChartPanAndZoomBehavior.UpdatePanAndZoom(Double startX, Double endX, Double startY, Double endY) in c:\TB\102\WPF_Scrum\Release_WPF\Sources\Development\Controls\Chart\Visualization\Behaviors\ChartPanAndZoomBehavior.Branch.cs:line 278

Can we extend the InputBox parsing logic?

Hi there,

We need to support some customised formats for user to type in the input box. e.g. if I type a "+5" in the input box today (03/03/2010), it needs to be converted to 08/03/2010 (the 5th day from today's date).

We've tried to bind a converter to the datepicker, but it's too late as the input has already been updated by the default parsing logic. And the fact that having inputText as a private member is not helping either.

So, Is there a way to change/extend the datepicker's default inputbox text parsing mechanism? Thanks in advance.

Cheers,

DatePicker
