Hi,

Before I begin, this is more of a question about a Popup control rather than the RadRichTextBox itself. Feel free to move this post if you think it should belong in a different section.
I've been creating my own RadRichTextBox Intellisense application where I'm positioning a Popup control based upon the caret position.

I know how to obtain the position of the caret, like so:

Point position = new Point();

if (!richTextBox.Document.CaretPosition.Location.IsEmpty)

{

position = richTextBox.ActiveEditorPresenter.GetViewPointFromDocumentPosition(richTextBox.Document.CaretPosition);

position.Offset(offsetX, offsetY);

return position;

}

The problem I have is that the Popup placement will alter depending on the size of the Popup/ListBox and if it is positioned towards the top or bottom of the screen.

When the the Popup is showing above my position point (the caret is the bottom of the screen) it is aligned in the correct place. However, should the caret be towards the top of the screen, the top edge of the Popup is aligned with the top of the caret.

You can better see what I mean from the attached images.

I need to some way to determine if the popup placement is Above or Below my point and adjust the vertical offset accordingly.

Thank you for your time,

Rob

Reduce the available fonts in the RadRichTextBoxRibbonUI

Hi,
I'm using RadRichTextBoxRibbonUI to handle a richtext box. By default the control creates a drop down list with all the available fonts of the system. I would like to restrict my user and provide him/her with specific ones. How do I do that?

Popup calendar behind the control

Hi,

we use V2012.1.326.35 of Telerik and our application run on a Virtual Machine and we access it through Windows Remote Desktop. If you look at the attached file, when I click on the button of my RadDatePicker to popup the calendar, the calendar appear behind my control. If I run our application directly on my computer, I tried to reproduce the problem without any success :( I remark that this problem occur with some other Telerik controls also like the filters dialog with the RadGridView controls.

Thank's

RadGridView: Binding multiple datatables

Hello,

I would like to know if its possible to bind multiple datatables to a single RadGridView? I need to bind a datatable to populate the grid and beside that I would also like to bind the column header properties.

xaml

<telerik:RadGridView Margin="0"

AlternationCount="2"

AlternateRowBackground="#d7e8ff"

AreRowDetailsFrozen="True"

AutoGenerateColumns="False"

CanUserFreezeColumns="False"

IsReadOnly="True"

ItemsSource="{Binding}"

SelectionMode="Single"

ShowInsertRow="False"

RowHeight="30"

RowIndicatorVisibility="Collapsed"

telerik:StyleManager.Theme="Office_Blue"

x:Name="Listing">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="ID" DataMemberBinding="{Binding Path=vis_ID}" IsVisible="False" Footer="Test"/>

<telerik:GridViewDataColumn Header="{Binding [str_gridview_lastname]}" MinWidth="150" DataMemberBinding="{Binding Path=vis_lastname}"></telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

cs

// Bind datatable to populate grid

Listing.DataContext = myDataTable;

// Bind column header text properties

Listing.DataContext = myColHeaderTable;

The second binding overrides the first binding. Any suggestion to bind both are welcome

Kind regards,
Dennis
