[Solved] RadCartesianChart Bar Series - two linear axes (plot a bar series like a scatter plot)

Hi All,

I am attempting to code a RadCartesianChart Bar series with two linear axes - similar to a scatter plot where there would be an X and Y coordinate, but instead of scatter points, I'd use a bar series; is anyone familiar with doing this?

In a nutshell I want to have time as the x axis - so I can plot a couple of data points where they would fall at any time from 0 to max, instead of having a Categorical axis where increment on the axis represents on category/value . I want them to be plotted freely on this axis, and at times overlap. (see attached radchartview-series-barseries - mine)

The y-axis would be a linear (dependent? ) axis as well, allowing me to plot my data point against a scale of kilo Joules 0 to the max.

Right now I am using C# WPF and just painting the points on a canvas and I had to paint grid lines and calculate the squares/scaling lines - very tedious. And telerik has some great pan, zoom and data point summary info on item click capabilities.

Please help

Many thanks

Kevin

Multiple row drag and drop between gridviews

Hi,
I've had a look at the Wpf-AutoDrag project which I found at this forum.
I've adjusted it to fit my wishes and all is find and dandy, BUT, how on
earth do I enable drag and drop for MULTIPLE rows? Right now I can
only move the rows one by one, which can be a tedious task if you need
to move like 50 rows every time. :(

I guess there's a simple solution to this issue, however I've still to find it, please help!

:)

RadButton content foreground not always correct with Office 2016 theme

Hi,

I noticed that the Office 2016 theme is the only theme where the RadButton foreground and background colors get inverted on mouse hover.

Unfortunately, if I do this, the text stays black even on mouse hover:

<telerik:RadButton>

<TextBlock Text="Test" />

</telerik:RadButton>

The following 2 versions work:

<telerik:RadButton Content="Test" />

<telerik:RadButton>

<telerik:RadButton.ContentTemplate>

<DataTemplate>

<TextBlock Text="Test" />

</DataTemplate>

</telerik:RadButton.ContentTemplate>

</telerik:RadButton>

But I cannot use the first because in reality the content I want to put in the button is more complex (TextBlock containing Run objects).
And the second would be a workaround which I would like to avoid as it is not the optimal way.

The reason it does not work is because the IsMouseOver trigger in the template does this:

<Setter TargetName="Content" Property="TextElement.Foreground" Value="{telerik1:Office2016Resource ResourceKey=MarkerInvertedBrush}"/>

By setting TextElement.Foreground on the ContentPresenter inside the control's template, only children that consider the ContentPresenter as their logical parent will inherit from its Foreground property.

When using the ContentTemplate property, the elements within the DataTemplate become logicial descendents of the ContentPresenter, so the inheritence of the Foreground property works.
When using the Content property, the logical parent of the topmost element that forms the content is not the ContentPresenter within the control's template, but the control (RadButton) itself. Therefore the foreground of the content will depend on the Foreground property of the control itself. The latter is not changed by the trigger, so it stays black, and so does the content's foreground.

The seemingly obvious fix would be to change the template trigger's setter to this:

<Setter Property="Foreground" Value="{telerik1:Office2016Resource ResourceKey=MarkerInvertedBrush}"/>

If you feel like this is an appropriate fix, please include it in future versions so that we do not have to customize your template just for that.
If not, and you have advice, you're welcome share it.

Best regards

Camera Behavior in RadCartesianChart3D

I am currently implementing RadCartesianChart3D to display some data. Everything seemed to be working perfectly fine, and I was mostly able to follow the examples provided by Telerik. However, it seems I am unable to set the Behaviors property of the RadCartesianChart3D.

<telerik:RadCartesianChart3D.Behaviors>

<telerikcv:Chart3DCameraBehavior />

</telerik:RadCartesianChart3D.Behaviors>

The above code block (set inside a RadCartesianChart3D) yields "The member Behaviors is not recognized or accessible".

References are set as follows:

xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Chart"

xmlns:telerikcv="clr-namespace:Telerik.Windows.Controls.ChartView;assembly=Telerik.Windows.Controls.Chart"

Export to Excel - maintaining cell color

In regard to your WPF grid, in some cases we set the background and/or the foreground color of certain cells, and would like to maintain these colors if and when the grid is exported to excel.

When the GridView_ElementExportingToDocument event is fired, a GridViewElementExportingToDocumentEventArgs object is passed. How can I use this object to determine the foreground and background color of the cell?

[Solved] How to use Scroll bar in Grid ?

Hi All,

I am using RadGridView for my WPF application and want to display vertical and horizontal scroll bar whenever the number of colums and rows are more.

I have set its Styles as folows :

<Style TargetType="{x:Type telerik:RadGridView}">

<Setter Property="HeaderRowStyle" Value="{DynamicResource GridViewHeaderRowStyle1}"/>

<Setter Property="AlternateRowStyle" Value="{DynamicResource AlternateRowStyle}"/>

<Setter Property="IsFilteringAllowed" Value="false"/>

<Setter Property="RowStyle" Value="{DynamicResource GridViewRowStyle}"/>

<Setter Property="GridLinesVisibility" Value="Both"/>

<Setter Property="Cursor" Value="Hand"/>

<Setter Property="VerticalGridLinesBrush" Value="#CCCCCC"/>

<Setter Property="HorizontalGridLinesBrush" Value="#CCCCCC"/>

<!--Setter Property="MinColumnWidth" Value="20"/>

<Setter Property="MaxColumnWidth" Value="150"/>

<Setter Property="ColumnWidth" Value="100"/-->

<Setter Property="RowIndicatorVisibility" Value="Collapsed"/>

<Setter Property="AlternationCount" Value="2"/>

<Setter Property="VerticalAlignment" Value="Top"/>

<Setter Property="HorizontalAlignment" Value="Center"/>

<Setter Property="ShowGroupPanel" Value="False"/>

<Setter Property="AutoGenerateColumns" Value="False"/>

<Setter Property="IsReadOnly" Value="True"/>

<Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto"/>

<Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Auto"/>

<Setter Property="IsScrolling" Value="True"/>

</Style>

Then in the main XAML i am using the following code :

<telerik:RadGridView x:Name="billDataGrid"

Grid.Row="5" >

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Name" Width="*" TextWrapping="Wrap"/>

<telerik:GridViewDataColumn Header="Address" Width="*" TextWrapping="Wrap" />

</telerik:RadGridView>

But when i am running my screen then I am not able to see the scroll bar even the data is very large.

Kindly let me know where i am wrong in defining the scroll bar.

[Solved] Change background of RadRibbonWindow

I'm using the fluent theme, but I'd like to change the RadRibbonWindow's background to a darker color. That's easy to achieve by setting the Background property. However, since the title bar's foreground is black, it is almost impossible to see the title and the minimize/maximize/close buttons anymore when I'm using a very dark color..

I've found a style defiition for telerikRibbonViewPrimitives:WindowTitle in Telerik.Windows.Controls.RibbonView.xaml and changed the Foreground color to white. This works for the title, but how can I change the color of the minimize/maximize/close buttons?

I've seen that I could do that by setting FluentPalette.Palette.IconColor, but this changes all icons, not only the window icons.

Thanks for your help!
