Setting GridViewRow.IsPinned through style

Hi

I'm trying to data-bind the IsPinned-property of the GridViewRow to a value from my model.

After numerous unsuccessful tries, I tried setting the IsPinned property to true through a style (see below).

However, the row is not pinned, also the button does not reflect the Pinned state.

How can I set the IsPinned-property through a property of my model?

01.<telerik:RadGridView Grid.Row="2" ItemsSource="{Binding Path=CalculablePersons}" GroupRenderMode="Flat" PinnedRowsPosition="Top">

02. <telerik:RadGridView.Resources>

03. <Style TargetType="{x:Type telerik:GridViewRow}" BasedOn="{StaticResource {x:Type telerik:GridViewRow}}">

04. <Setter Property="IsPinned" Value="True" />

05. </Style>

06. </telerik:RadGridView.Resources>

07.

08. <telerik:RadGridView.Columns>

09. <telerik:GridViewPinRowColumn />

10. <telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Path=Name}" />

11. </telerik:RadGridView.Columns>

12.</telerik:RadGridView>

multiple legends on radMap

hello,

I want to present multiple legends on radMap, each legend item I want to present is actually a userControl that I build and it contains spectrum, numbers and some other buttons and options.

my final result is to have the map layer and above it a layer in witch allow the user drag and drop the legends all over the map (in order to place them wherever he wants)

so basically i need a layer that:

1. transparent

2. I want it not to block the layer below it

3. I want it to allow drag and drop

attached a png to show what i mean

I'm trying to use itemsControl in information layer in order to bind MapLeged to it but no success.. nothing presented on the map

this is my code in generally:

<telerik:RadMap>

<telerik:InformationLayer x:Name="informationLayer">

<ItemsControl itemsSource= " {Binding LayersProvider.Layers} "

<ItemsControl.ItemsPanel>

<ItemsPanelTemplate......./>

</ItemsControl.ItemsPanel>

<ItemsControl.ItemTemplate>

</DataTemplate>

</ItemsControl.ItemTemplate>

</ItemsControl>

</telerik:InformationLayer>

<telerik:VisualizationLayer......................./>

</telerik:RadMap>

<telerik:MapLegend x:Name="mapLegend"

Layer="{Binding informationLayer}" />

maybe you will have an idea for me.

thank you so match

StepLine and Marking Annotation Issue

Hi Telerik,

We are facing two issues when we are using Stepline series.

ISSUE 1 :

When there is only one category / data point then chart is not drawing . We have such cases  and we need solution or workaround for this case

<telerik:StepLineSeries>

<telerik:StepLineSeries.DataPoints>

<telerik:CategoricalDataPoint Category="1" Value="1.0" />

<!--<telerik:CategoricalDataPoint Category="2" Value=1.1" />

<telerik:CategoricalDataPoint Category="3" Value="1.0" />

<telerik:CategoricalDataPoint Category="4" Value="1.1" />-->

</telerik:StepLineSeries.DataPoints>

</telerik:StepLineSeries>

ISSUE 2 :

We are using marked zone but marking falling in between and not from beginning so we used margin workaround from telerik to fix (Please see code from attached xaml.cs file)

Before Shifting

See image

After Shifting

See image

BELOW CODE USED TO ALIGN MARGIN

int categoriesCount = this.horizontalAxis.Categories.Count();

double categorySlotSize = this.chart.PlotAreaClip.Width * this.chart.Zoom.Width / categoriesCount;

var margin = new Thickness(-(categorySlotSize / 2), 0, 0, 0);

if (!margin.ToString().Contains("Infinity"))

{

this.chart.Annotations.Where(x => x is CartesianMarkedZoneAnnotation).ToList()

.ForEach(m => { m.Margin = margin; });

}

But we are facing issue when we zoom the chart.The marking going out of actual area.Please help to resolve it.

After Zooming

See Image

ISSUE 3 :

When we are using marking for last category then the marking done for half way only.Please help to draw until end (Need to support while zooming as well)

<telerik:StepLineSeries>

<telerik:StepLineSeries.DataPoints>

<telerik:CategoricalDataPoint Category="1" Value="1.0" />

<telerik:CategoricalDataPoint Category="2" Value="1.1" />

<telerik:CategoricalDataPoint Category="3" Value="1.0" />

<telerik:CategoricalDataPoint Category="4" Value="1.1" />

</telerik:StepLineSeries.DataPoints>

</telerik:StepLineSeries>

<telerik:CartesianMarkedZoneAnnotation VerticalFrom="1.0" VerticalTo="1.1" HorizontalFrom="4" Fill="Red"/>

Timebar Animation Exception, Version 2011.1.405.40

Hi,

I have the license for version 2011.1.405.40. And in this version, i am getting the Animation exception whenever i move the mouse over the timebar control. Apparently it is trying to access Hand property of Cursor and it is unable to animate it over the Border control. Following is my code:

<telerik:RadTimeBar x:Name="timeBar"

Width="950"

Height="250"

PeriodStart="01-01-2011"

PeriodEnd="01/01/2012"

VisiblePeriodStart="01/01/2011"

VisiblePeriodEnd="06/01/2011"

SelectionStart="02/01/2011"

SelectionEnd="03/01/2011"

MinSelectionRange="28.00:00:00"

MaxSelectionRange="31.00:00:00"

IsSnapToIntervalEnabled="True">

<telerik:RadTimeBar.Intervals>

<telerik:YearInterval/>

<telerik:MonthInterval/>

<telerik:WeekInterval/>

<telerik:DayInterval/>

<telerik:MinuteInterval IntervalSpans="1,10,15,30"/>

<telerik:SecondInterval IntervalSpans="10,15,30"/>

</telerik:RadTimeBar.Intervals>

</telerik:RadTimeBar>

I have attached the image of exception as well. The newer version does not have this bug, but I cannot upgrade due to compatibility issues. I hope that there is a fix for this, disabling the animation or something like that.
Waiting for your early response. Thanks!

MeasureOverride Performance

I seem to be having some issues with a TreeListView placed inside a Grid with a single Row with Height="*" (as indicated here http://docs.telerik.com/devtools/wpf/controls/radgridview/troubleshooting/performance), with some severe performance issues when scrolling either vertically or horizontally: TreeListCellsPanel.MeasureOverride seems to be a bottleneck, and placing a breakpoint at this method indicates that this function is called successively with availableSize equals to either {0; 26} or {+Inf, +Inf}. Adding more rows or columns makes this even worse.

RadGridView scrollbar speed adjustment

Hi,

I could not find out how to adjust speed options of RadGridView scrollbar. Actual behaviour is that the more is scrollbar moved by mouse the speed is increased. Grid is showing complex data so scrolling with higher speeds in combination with more rows leads to scroll tearing. The more is speed the tearing is worse.

One solution is to set scrolling to be deffered, another one is to optimize columns, data bindings etc. and try result but I would like also to know how to fix speed at some pages a time or something like that.

Thank you very much.

Detect moved shape from container to diagram

If I move a shape from diagram to a container, i can attach the OnCollectionChanged() in the container to detect the moved shape. But, if I move the shap back to diagram, i dont have method to attach the change event in the diagram control. because the shape is already added in the graphsource, so the AddItem() method isnt invoked.

How can i detect a shape that is moved from container to diagram?

Thanks for a replay!
