RibbonWindow and docking

Hello

I found a bug i cannot solve on my own

When you put RadDocking on RadRibbonWindow
Compass gets a strange translation to the right and bottom
same as all his markers

what i want to do is to combine docking with RibbonView on one window

Overview of code:

<telerik:RadRibbonWindow>
<DockPanel>
<telerik:RadRibbonView DockPanel.Dock="Top" />
<telerik:RadDocking/>
</DockPanel>
</telerik:RadRibbonWindow>

All works perfect except the problem i described :

Compass, transparent overlays that shows where new panel will be docked and markers are translated to the right and bottom

Export to PDF

HI, I have a problem to export my document to PDF file radrichtexbox to the error shown is: "Operation is not valid due to the current state of the object".

This happens sometimes, it seems the problem is in the format that takes the document to put bullets.
My process for creating the PDF document is:

Try
ProviderPdf Dim As New PdfFormatProvider PdfFormatProvider = ()
Using output As Stream = File.Open (AppDomain.CurrentDomain.BaseDirectory & "\ temp \" & Label1.Content &. "Pdf", FileMode.Create)
providerPdf.Export (RadRichTextBox1.Document, output)
End Using
Catch ex As Exception
MsgBox (ex.ToString)
End Try

The stack trace is:
   in Telerik.Windows.Documents.FormatProviders.Pdf.RadPdf.PdfFontPool.get_Item (Span span) in 54
   in writer, Paragraph Paragraph, RectangleF rect) in 64
   in writer, Paragraph paragraph) in 84

Menu item disabling itself?

I have a main window that contains a RadMenu and a RadDocking.

When I select a menu item, I add a new RadPane to the RadDocking's RadPaneGroup. If I select the menu item multiple times, I get multiple RadPane's added, which is what I want.

The odd thing is that if I close one of the RadPanes, by clicking on its corner 'x' icon, the menu item disables itself. So once I close a pane, I can no longer open any more.

I can envision of no mechanism by which this could be happening, but happening it is.

I've created a stripped-down solution that demonstrates the problem. It works out to a 8.7MB zip file. I can't attach it here, should I email it to someone?

Prevent user from using the backspace key to leave value blank

I am using a ComboBox with the following settings:

<Setter Property="TextSearchMode" Value="StartsWith" />

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

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

Is there a codeless (MVVM) way to force a valid value to be chosen? As it stands, the user can click into the "TextBox" part of the RadComboBox, hit the backspace key repeatedly to clear out the text, and effectively set the value to null. This is even though the ComboBox does not have a null / blank value available for selection via the mouse / arrow keys.

The ideal situation would be to return the ComboBox to its original value if the user does not select a valid value.

I'm sure there is a method of doing this via code behind, but this seems like something that could already be built into the control.

Thank you,
Kevin

How to control display of rows in RadGridView

I've got a RadGridView on a WPF form. The control is in a cell of a Grid control. The cell isn't tall enough to show a full number of rows all of the same height. That is, the last row at the bottom is displaying as a partial row.

When I scroll all the way down to the bottom, the last row is not displaying fully. Even though the scroll bar is all the way down, it doesn't scroll the whole last row into view.

How do I fix this so the last row will display in full?

Tony

Edit: Here is the XAML for the RadGridView control:

<my:RadGridView AlternationCount="1"

AutoExpandGroups="True"

AutoGenerateColumns="False"

CanUserDeleteRows="False"

CanUserFreezeColumns="False"

CanUserInsertRows="False"

CanUserResizeColumns="True"

CanUserSortColumns="True"

DataLoadMode="Asynchronous"

EnableColumnVirtualization="True"

EnableRowVirtualization="True"

FontSize="18"

FontWeight="Bold"

Grid.Column="1"

Grid.Row="1"

IsReadOnly="True"

Margin="5"

Name="HotListResults"

SelectionChanged="HotListResults_SelectionChanged"

SelectionUnit="FullRow"

ScrollViewer.CanContentScroll="True"

ScrollViewer.HorizontalScrollBarVisibility="Auto"

ScrollViewer.VerticalScrollBarVisibility="Auto"

ShowGroupFooters="True"

ToolTip="Matching Hot List Entries">

<my:RadGridView.Columns>

<my:GridViewDataColumn DataMemberBinding="{Binding ListName, Mode=OneWay}" Header="Hot List" Width="150" />

<my:GridViewDataColumn DataMemberBinding="{Binding AlarmClass, Mode=OneWay}" Header="Alarm Class" Width="200" />

<my:GridViewDataColumn DataMemberBinding="{Binding CountryId, Mode=OneWay}" Header="Country" Width="100" />

<my:GridViewDataColumn DataMemberBinding="{Binding LocaleCode, Mode=OneWay}" Header="State" Width="75" />

<my:GridViewDataColumn DataMemberBinding="{Binding Plate, Mode=OneWay}" Header="Plate" Width="150" />

<my:GridViewDataColumn DataMemberBinding="{Binding BeginDate, Mode=OneWay, Converter={StaticResource DateConverter}}" Header="Begin Date" Width="200" />

<my:GridViewDataColumn DataMemberBinding="{Binding EndDate, Mode=OneWay, Converter={StaticResource DateConverter}}" Header="End Date" Width="200" />

</my:RadGridView.Columns>
