Points below minimum value showing with PointTemplate

I'm having an issue where my chart is displaying values on that minmum axis that should be below that axis. This is using a PointTemplate to show a BarSeries as points. This happens for both logarithmic and linear axes. Example is as follows:

<Window x:Class="ZeroLogAxis.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

Title="MainWindow" Height="350" Width="525">

<Grid>

<telerik:RadCartesianChart>

<telerik:RadCartesianChart.Resources>

<DataTemplate x:Key="PointTemplate">

<Ellipse Width="8" Height="8"

VerticalAlignment="Top"

Margin="-4,-4,0,0"

Fill="Black" />

</DataTemplate>

<Style TargetType="telerik:BarSeries">

<Setter Property="PointTemplate"

Value="{StaticResource PointTemplate}" />

</Style>

</telerik:RadCartesianChart.Resources>

<telerik:RadCartesianChart.HorizontalAxis>

<telerik:DateTimeContinuousAxis

LabelFitMode="Rotate" LabelFormat="dd-MMM-yy" />

</telerik:RadCartesianChart.HorizontalAxis>

<telerik:RadCartesianChart.VerticalAxis>

<telerik:LinearAxis Minimum="3" Maximum="6" />

</telerik:RadCartesianChart.VerticalAxis>

<telerik:RadCartesianChart.Series>

<telerik:BarSeries Name="BarSeries" />

</telerik:RadCartesianChart.Series>

</telerik:RadCartesianChart>

</Grid>

</Window>

Code Behind:

public MainWindow()

{

InitializeComponent();

for (int i = 1; i < 6; i++)

BarSeries.DataPoints.Add(

new Telerik.Charting.CategoricalDataPoint()

{ Category = DateTime.Today.AddDays(i), Value = i });

}

With a Minimum="3" on my VerticalAxis, I would expect to see half of the "3" point, and the full 4 and 5 point. However, I'm also seeing half a point on the axis for the 1 and 2 values, as indicated by the red arrows in the attached screenshot.

Any suggestions on how to not display points that should not be on the chart?

Thanks,

Louis

Use RichTextBox to Send Email

Hi,

I am using a RadRichTextBox to allow a user to write the content of an email. I export the content to HTML and use this as the content of the email. I am unable to get images pasted into the RadRickTextBox to appear in the email (although when viewing the HTML in chrome the image is there). I was wondering if you had encountered a similar situation before, or if you had any idea how to solve this issue.

I have attached an image of what I get when the email opens in outlook

Thanks,

Steven

All group headers recreated on every expand / collapse / add group / remove group

Hi there,

I have a RadGridView with a GroupHeaderTemplate. Every time any group is expanded / collapsed or a new column grouping is added or removed, all group header controls (as defined in the GroupHeaderTemplate) are unloaded and new ones are created. Is it possible to stop this behaviour so that all group header controls are not recreated on every action?

Thanks

How to move RadToolBars inside RadToolBarTray

We have several RadToolBars inside a RadToolbarTray and the user of the application should be able to shift these RadToolBars around inside the Tray. So that he can customize his Tray depending on screen size.

How do we get this done? The IsLocked property shows no effect.

Insert Defined Name in formula

Hi,

Please note that I posted this question a few days ago, but it seems to have been deleted, so I am posting it again.

I have modified the WorksheetEditorContextMenu so that a user can right click on a cell and select from the context menu one of the Workbooks currently Defined Names. I need the selected Defined Name to be inserted at the cursor position of the selected cell.

For example if the cell already has =A1+ typed in it and the user right clicks and selects the Defined Name TotalKMs the cell should then read =A1+TotalKMs with the ability for the user to keep tying the rest of the formula.

I am currently achieving what I require by setting the text on the Clipboard and calling radSpreadsheet.CommandDescriptors.Paste.Command.Execute(null).

This is a poor solution because the clipboard should not be used by applications in this manner.

Is there a better way to achieve this?

Thanks
Anthony

BringPathIntoView Not Working With ExpandAll

Hello,

after I load the tree I want to expand all items, then call BringPathIntoView(). This does not work. If I do not call ExpandAll(), BringPathIntoView will select the correct item. My requirement is that I expand the whole tree and select a specific item based on certain rules. Here's my code:

radTreeView.ItemsSource = _radTreeViewItems;

radTreeView.ExpandAll();

radTreeView.BringPathIntoView("something\\somethingChild");

The "something\\somethingChild" path is an item near the bottom of a large tree and it does not scroll down. Is there a way to wait for the ExpandAll() method to finish, then call BringPathIntoView?

Thanks,

Scott

Displaying RTF file containing binary picture data

Is it possible to display RTF files in the RadRichTextBox that contain binary picture data? I have a stripped-down file that contains a jpegblip\bin tag which the RadRichTextBox does not display. The first line of the file is:

{\rtf1{\pict\picw2700\pich2700\picwgoal2700\pichgoal2700\jpegblip\bin9889

I created a second file with the binary data converted to hex data and the text box shows the image as expected. The first line of that file is:

{\rtf1{\pict\picw2700\pich2700\picwgoal2700\pichgoal2700\jpegblip

While the binary data contents of pictures is a part of the RTF standard, is this part of the standard supported by RadRichTextBox?

NB: I have two RTF files that demonstrate the issue, however only images can be attached this thread.

Thanks,
Jason.

Cant create connections interactively

I am using the diagram view in MVVM mode and I have built my test app starting from the MVVM SDK sample and the Class Diagram demo.

I can create shapes and connections programmatically. Connections created programmatically can be edited. I am using "gliding" connectors. My test app is able to create new shapes by dragging/dropping shapes from the toolbox. However, I cant create new connections interactively. When I click a shape, the center point of the shape shows up, when mousing over it, it gets highlighted and the tooltip "Connect" does appear. I am getting ConnectorManipulationStarted event. When dragging the mouse away no connector is showing up, and no Completed event ever fires. I have made sure that every editing related property is enabled on shapes, connectors and diagram style, but nothing...

Any idea ?

Thanks !

L.
