ChartTrackBallBehavior CommandParameter Issue

Hi,
first of all I'm using the MVVM pattern.

In order to get the ActualVisibleRange from my DateTimeContinuousAxis i hooked up to the LayoutUpdated event and passed the axis via the CommandParameter:

<telerik:DateTimeContinuousAxis x:Name="horizontalAxis" LabelFormat="dd.MM hh:mm" LabelFitMode="MultiLine">

<i:Interaction.Triggers>

<i:EventTrigger EventName="LayoutUpdated">

<i:InvokeCommandAction Command="{Binding LayoutUpdatedCommand}" CommandParameter="{Binding ElementName=horizontalAxis}"/>

</i:EventTrigger>

</i:Interaction.Triggers>

</telerik:DateTimeContinuousAxis>

When I apply this pattern to the ChartTrackBallBehavior to pass the Data of the Behavior i got an error:

<telerik:ChartTrackBallBehavior x:Name="trackBallBehavior" ShowTrackInfo="True">

<i:Interaction.Triggers>

<i:EventTrigger EventName="TrackInfoUpdated">

<i:InvokeCommandAction Command="{Binding TrackInfoUpdatedCommand}" CommandParameter="{Binding ElementName=trackBallBehavior}"/>

</i:EventTrigger>

</i:Interaction.Triggers>

</telerik:ChartTrackBallBehavior>

Is there an alternative way to pass the data of the ChartTrackBallBehavior to my ViewModel?

Regards Markus

Change chart palette

Hi,

I was looking the chart appearance demo and I want to implement something like that, I am using a RadChart with PieSeriesDefinition, a RadRadialGauge and a RadChart with AreaSeriesDefinition, I can't find how to apply the palette, I also have a RadPolarChart and a RadCartesianChart and I have no problem assigning the palette.

I don't know if for the first 3 charts is not possible assign a palette or it works in a different way.

Thanks,

Alberto

RadWindow.Show() behaviour

Hi

I am using a RadWindow as the apps Main window. What i want to do is create a second Window using RadWindow.Show() which means IsModal = false which is what I want. However, when I click into the main window the second window stays on top. How do I get either window to be on top when clicked-in. The only way I can get the mainwindow on top is by minimizing the second window. I need these two windows to be loosely coupled.

Thanks
Rich

ScrollPositionIndicatorTemplate doesn't show all content

I have implemented this on a grid that I have, and I have noticed that even if I click and drag the scroll bar to the very bottom, it doesn't show the bottom-most record. I have also noticed this same behavior in your WPF Example for this feature. Is this a known issue?

RadButton Command in GridViewColumn doesn't Work sometimes

Dear telerik,

I have to fix a problem in our software and we are using a gridview, which contains articles as items.
Each Item has a deletebutton (only visible for the the selected one), which Command is bound on a DelegateCommand (in the ViewModel). We are using the MVVM-pattern.
This button is only for removing the selected item of the gridview and works fine but when i have more than 16 articles in the grid there is always one or two articles, which I can't delete with the button. The other ones work fine.

The routed method doesn't get called in this times and I don't know why. A Button Click Event always works even when the bound command doesn't work.

I don't know where I have to search this mistake and would like to use the command and not the buttonclick.

Did you ever hear of a problem like this? Could you please help me?

Thanks a lot.

Cheers

Frank

BusyIndicator with RadCartesianChart

Hello,

I am trying to implement a BusyIndicator when loading data into a RadCartesianChart.

I have this code:

<telerik:RadBusyIndicator Name="busyInd" HorizontalAlignment="Left" Grid.Row="1" Margin="10,10,0,0" VerticalAlignment="Top" Height="255" Width="372" IsIndeterminate="True">

<telerik:RadCartesianChart x:Name="CartesianChartDemo" Grid.Column="5" Margin="10" Grid.Row="2" Grid.ColumnSpan="3">

<telerik:RadCartesianChart.Behaviors>

<telerik:ChartPanAndZoomBehavior PanMode="Both" ZoomMode="Both"/>

</telerik:RadCartesianChart.Behaviors>

</telerik:RadCartesianChart>

</telerik:RadBusyIndicator>

I load data in the code behind file:

CartesianChartDemo.VerticalAxis = new CategoricalAxis();

CartesianChartDemo.HorizontalAxis = new LinearAxis();

CartesianChartDemo.Grid = new CartesianChartGrid() { MajorLinesVisibility = GridLineVisibility.XY };

string strQuery = "MyQuery";

//Function to get datatable

DataTable dtAlloys = DataRetriever.GetDataTable(strQuery);

BarSeries barSer = new BarSeries();

barSer.ShowLabels = true;

barSer.CombineMode = ChartSeriesCombineMode.Cluster;

BarSeries barSer2 = new BarSeries();

barSer2.ShowLabels = true;

barSer2.CombineMode = ChartSeriesCombineMode.Cluster;

foreach (DataRow drAlloy in dtAlloys.Rows)

{

barSer.DataPoints.Add(new CategoricalDataPoint() { Category = drAlloy["MATERIAL_CODE"], Label = string.Format("{0:N}", drAlloy["WT"]), Value = double.Parse(drAlloy["WT"].ToString()) });

barSer2.DataPoints.Add(new CategoricalDataPoint() { Category = drAlloy["MATERIAL_CODE"], Label = string.Format("{0:N}", drAlloy["TARG"]), Value = double.Parse(drAlloy["TARG"].ToString()) });

}

CartesianChartDemo.Series.Clear();

CartesianChartDemo.Series.Add(barSer);

CartesianChartDemo.Series.Add(barSer2);

I was thinking to add:

busyInd.IsBusy = true;

//Code to load data

busyInd.IsBusy = false;

But I'm not sure if this is the way the BusyIndicator works.

Does anyone has any pointers to accomplish that?

Regards,

Alberto
