RadComboBox and CanAutocompleteSelectItems

I'm using the following setttings on my combobox..

<telerik:RadComboBox x:Name="cboUppdragsmallar" Text="{Binding Namn, UpdateSourceTrigger=LostFocus}" EmptyText="Uppdragsnamn" Height="40" FontSize="18"
DockPanel.Dock="Top" Margin="5 10 5 5" ToolTip="Uppdragsnamn" IsEditable="True" ItemsSource="{StaticResource UppdragsmallLista}" DisplayMemberPath="Namn" CanAutocompleteSelectItems="False" SelectionChanged="cboUppdragsmallar_OnSelectionChanged" />

My intention is to let the user pick a name for a project, if he wants he can use the dropdown to select a predefined template that lets picks some information of the template to fill certain fields.

However the CanAutocompleteSelectItems does not seem to work because as soon as i type something in the dropdown it autocompletes and fired selectionchanged which fills all the fields with data from the template being selected.. I don't want this behaviour unless the user selectes an option from the dropdown by hand...

So What i want is for the selectionchanged event only to fire when a dropdown selected is made by mouseclick or by keyboard. Not by autocompletion!

add dropshadow to calendar picker?

I have what seems like it should be an easy question - how do i simply add a dropshadow to the calendar picker that is shown in the popup after selecting the calendar icon of a datetimepicker? I've tried editing the PART_Popup in my custom style, however the dropshadow just gets ignored. is there a secondary calendar control somewhere i need to modify or create a custom style for?

What Series to use to get Category val for TrackBall

I am using just a LineSeries and setting it's ItemSource to uint array and when I use the TrackBall I just get the Y-value and not the Category one.
My guess is I need to use a different series type such as ScatterSpline, but I couldn't figure out how to specify data for that sort of series. My array updates 30 times a sec so I'm constantly nulling out the series ItemSource and setting it back to the uint array
Also, is it possible to change the "Category" label in the TrackInfo box to something else such as "Channel?"

Thanks!

My ChartView in XAML

<telerik:RadCartesianChart Grid.Row="0"

Name="radCartesianChart1"

>

<telerik:RadCartesianChart.HorizontalAxis>

<telerik:CategoricalAxis

MajorTickInterval="255"

LabelInterval="1"

ShowLabels="True"

/>

</telerik:RadCartesianChart.HorizontalAxis>

<telerik:RadCartesianChart.VerticalAxis>

<telerik:LinearAxis />

</telerik:RadCartesianChart.VerticalAxis>

<telerik:RadCartesianChart.Behaviors>

<telerik:ChartPanAndZoomBehavior ZoomMode="Both"

PanMode="Both">

</telerik:ChartPanAndZoomBehavior>

<telerik:ChartTrackBallBehavior ShowIntersectionPoints="True"

ShowTrackInfo="True"/>

</telerik:RadCartesianChart.Behaviors>

<telerik:RadCartesianChart.Series>

<telerik:LineSeries Stroke="Orange"

StrokeThickness="2"/>

</telerik:RadCartesianChart.Series>

</telerik:RadCartesianChart>

My CodeBehind where I set the ItemSource when my array upda

void setData(uint[] data)

{

//may use with ScatterSplineSeries??

//List<PlotInfo> dataList = new List<PlotInfo>();

//for (int i = 0; i < _EDSData.Length; i++)

// dataList.Add(new PlotInfo() { XVal = i, YVal = _EDSData[i] });

radCartesianChart1.Series[0].ItemsSource = null;

radCartesianChart1.Series[0].ItemsSource = _EDSData;

}

Thanks!

[Solved] UI Virtualization of DataFormComboBoxField

Hi,

I am trying to UI Virtualize a DataFormComboBoxField through styling, but could not find a way to do that.I copied the DataFormComboBoxField style in Blend but was not able to find the combo box on which to set the ItemsPanel to VirtualizingStackPanel.I am now doing through code and it works fine, but would like to move that to global style.

IEnumerable<DataFormComboBoxField> comboFields = MyRadForm.ChildrenOfType<DataFormComboBoxField>();

foreach (DataFormComboBoxField comboField in comboFields)

{

((RadComboBox)comboField.Content).ItemsPanel = Resources[

"VirtualizingItemsPanelTemplate

"

] as ItemsPanelTemplate;

}

<ItemsPanelTemplate x:Key="VirtualizingItemsPanelTemplate">

<VirtualizingStackPanel />

</ItemsPanelTemplate>

Thanks

Sorting does not work after DataLoadMode is set to Asynchronous

Hi,

I am binding my GridView to QueryableDataServiceCollectionView<T> to load data from a WCF Data Service.I wanted to disaplay the grid built-in busy indicator when paging/sorting the grid, so I set DataLoadMode to Asynchronous.Paging works fine and the busy indicator is shown when data is being fetched but sorting stopped working.Clicking on the column header does not trigger anything.

MyEntities db = new MyEntities(Global.DataServiceUri);

var query = db.Sims;

QueryableDataServiceCollectionView<Sim> dataContext = new QueryableDataServiceCollectionView<Sim>(db, query);

dataContext.PageSize = 20;

dataContext.AutoLoad = true;

DataContext = dataContext;

<telerik:RadGridView DataLoadMode="Asynchronous" Name="SimsGridView" ItemsSource="{Binding}" CanUserFreezeColumns="False"

AutoGenerateColumns="False" MouseDoubleClick="SimsGridView_MouseDoubleClick">

Environment:
VS 2012
RadControls 2012 Q3
.NET 4.5
WCF 5.0

Thanks

RadGridview Group Panel Height

I am Working on customizing a RadGridview and can't seem to find any way to change the height of the grouping panel. I want to make it a little bit smaller. Is there a way to do this built-in to the control? Or maybe even a work around that anyone has found?

Here is the code that I have now.

telerik:RadGridView Name="ExceptionsListBox"

IsReadOnly="True"

UseLayoutRounding="False"

EnableRowVirtualization="True"

AutoGenerateColumns="False"

RowIndicatorVisibility="Collapsed"

Background="#FF202020"

RowHeight="20"

GroupPanelBackground="#FF202020"

GroupPanelForeground="white"

telerik:StyleManager.Theme="Expression_Dark">

<telerik:RadGridView.Resources>

<Style TargetType="telerik:GridViewHeaderRow">

<Setter Property="MinHeight" Value="15" />

</Style>

</telerik:RadGridView.Resources>

<telerik:RadGridView.Columns >

<telerik:GridViewDataColumn DataMemberBinding="{Binding TruckCode}"

Header="Truck"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Content}"

Header="Content" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

Thanks for any help.

Control Y-Axis growth

For say a line chart is it possible to tweak the way the Y-Axis grows? It appears to grow a certain percent every time the highest bin reaches the top of the chart. Instead I’d like the highest bin to be 85 or 90% of the Y-Axis height at all times so live-data graph is not so jumpy. A code snippet would be greatly appreciated!
