Today I discovered the following file in my build folder: Telerik.Windows.Data.dll

Upon further research, I discovered that this file is listed as a dependency for RadMap:
http://docs.telerik.com/devtools/wpf/installation-and-deployment/deploying-telerik-ui/installation-installing-dependencies-wpf.html

I have 3 projects using the map and only one has this file in the build folder. Two are using WPF 4.5 and one is using WPF 4.0. I've been sending out the installations for years without this file and haven't had a problem. Can you explain why this file is needed? Also any idea why it is only just now showing up for this one project?

These are the two files I am actually referencing:
C:\Program Files (x86)\Telerik\UI for WPF\Binaries.NoXaml\WPF45\Telerik.Windows.Controls.DataVisualization.dll
C:\Program Files (x86)\Telerik\UI for WPF\Binaries.NoXaml\WPF45\Telerik.Windows.Controls.dll

Inconsistent error notification behavior between "Full Row" and "Cell" selection units

If "Full Row" selection unit is used, and particular field has an error, the row header displays an error icon summarizing the errors when hovered over (see attached "error - full row selection unit.jpg"). This is not the case when "Cell" is the selection unit (see "error - cell selection unit.jpg").

Do I need to set something to enable the same behavior, or is this a bug?

I am using trial version (2015.3.1104.45)

RadCartesianChart: Label of BarSeries are showing wrong position when windows is resized

Hi,

I'm trying to make a bar chart with long text of categories, so I wrapped them all by the following code

xaml

<Grid SizeChanged="Grid_SizeChanged">

<telerik:RadCartesianChart Grid.Row="0"

x:Name="ChartSeries"

>

<telerik:RadCartesianChart.HorizontalAxis>

<telerik:CategoricalAxis ClipToBounds="False" HorizontalLocation="Right" SmartLabelsMode="SmartStep" IsStepRecalculationOnZoomEnabled="True">

<telerik:CategoricalAxis.LabelTemplate>

<DataTemplate>

<TextBlock TextWrapping="Wrap" MaxWidth="{Binding ElementName=Self, Path=MaxWidthTextBlock}" Text="{Binding}" />

</DataTemplate>

</telerik:CategoricalAxis.LabelTemplate>

</telerik:CategoricalAxis>

</telerik:RadCartesianChart.HorizontalAxis>

<telerik:RadCartesianChart.VerticalAxis>

<telerik:LinearAxis Minimum="0"

RangeExtendDirection="Positive"

SmartLabelsMode="SmartStep"

>

</telerik:LinearAxis>

</telerik:RadCartesianChart.VerticalAxis>

<telerik:BarSeries ShowLabels="False" ClipToPlotArea="False">

<telerik:BarSeries.DataPoints>

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

<telerik:CategoricalDataPoint Category="TextTextTextTextTextTextTextTextText" Value="5" />

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

<telerik:CategoricalDataPoint Category="TextTextTextText" Value="10" />

<telerik:CategoricalDataPoint Category="TextTextTextTextTextTextTextTextTextTextTextTextText" Value="9" />

<telerik:CategoricalDataPoint Category="TextTextTextText" Value="7" />

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

</telerik:BarSeries.DataPoints>

</telerik:BarSeries>

<telerik:RadCartesianChart.Grid>

<telerik:CartesianChartGrid MajorLinesVisibility="Y" x:Name="Line">

<telerik:CartesianChartGrid.MajorYLineStyle>

<Style TargetType="Line">

<Setter Property="Stroke" Value="DarkGray"/>

</Style>

</telerik:CartesianChartGrid.MajorYLineStyle>

</telerik:CartesianChartGrid>

</telerik:RadCartesianChart.Grid>

</telerik:RadCartesianChart>

</Grid>

As you can see, I have a method to recalculate the maxwidth of textblock when the container's size is change(Grid) as the following code behind

private void Grid_SizeChanged(object sender, SizeChangedEventArgs e)

{

if(e.PreviousSize.Width != 0)

{

var ratio = e.NewSize.Width / e.PreviousSize.Width;

MaxWidthTextBlock *= ratio;

}

The calculation seems to compute correctly for max width of the textblock but the position of the label is not correct. It seems to be a bit right aligned.

Do you have any idea to make it center as before windows size is changed, please advise ?

I also attached the image for before / after windows size change.

Best Regards,
Witt

[Solved] Inconsistent Enter key handling between "FullRow" and "Cell" or "Mixed" selection units

I'm running into various issues with buggy behaviour between row and cell selection units. To start with, when cell is in view mode and SelectionUnit="FullRow", pressing "Enter" keys moves to the cell below ... perfect! However, if SelectionUnit="Cell" pressing "Enter" does nothing. Is this a known bug? I wired up a custom keyboard command provider to see what commands are being generated, and sure enough, I see 3 commands queued up: Activate, MoveDown, and Select the current unit. However, they are not actually invoked, or fail at some point, if they are invoked.

This behaves as expected when cell is in edit mode.

Inconsistent behavior and styling between column headers and column group headers

I've been evaluating a number of data grids from various vendors, and the way Telerik handles stacked column headers (GridViewColumnGroup) seems to be the most awkward and restrictive of them all. A couple of points to start with:

The group column headers styling does not match the style of the column headers as per selected theme (see attached "column group default header style.jpg"). I was able to hack something by wasting my time finding the style of the column header, and creating a custom style based on CommonColumnHeaderStyle to target CommonColumnHeader, which is obviously a convoluted way of getting this done. Am I missing something? How can I apply the same theme to the group column headers without resorting to hacking? This simply works out of the box with grids of other vendors, like ComponentOne FlexGrid, or DevExpress data grid.
It appears the behavior of the group column headers differs from column headers. For instance, the hover over visual state is not consistent between these column headers. Also, I cannot resize columns from group column headers. Again, this is something other grids support out of the box with no effort on the part of the developer. What am I missing?

In short, I would like consistent behavior between group column headers and column headers. I'd appreciate any insight on this subject.
