RichTextBox: Inserting an inline image goes partially on top of the previous line

Hi!

I'm trying to add an inline image to a RadRichTextBox by dragging and dropping the image from elsewhere in my application. I noticed that sometimes the image goes partially on top of the previous line as shown in the attached picture. Even when changing the wrapping style between square and top-and-bottom, it doesn't get fixed.

I wonder what's causing this? Is there a way to work around this? Could it be just my Visual Studio?

Thanks!

itemssource is updated in a different thread, how to update GridView, with losing filter or sorting?

Hi,

I've been struggling a bit with the radgridview since the Itemssource can be updated somewhere else, but the thing is, it's the full collection that gets updated, and when this happens, the entire sorting/filter is lost.

I assume I have to make sure that only one specific item in the collection gets modified, but not quite sure what the best approach is here, since the collection is filled with Telerik DataAccess entities and if I'm not wrong there is not Inotifyproperty on the entities.

Overflow not working when hosted in Excel addin

I'm using a RadToolBar in an Excel task pane. When the task pane is sized to move controls to the overflow, the overflow button will enable but clicking the overflow button will not display the controls. I've further narrowed the problem to when the WPF user control is converted to an INativeControlHandle and back before adding it to the task pane.

I've built a sample project to demonstrate the problem. The sample also includes a regular WPF ToolBar which does not have the same problem. (remove the .jpg extension from the .zip file)

Note that the same code hosted in a Word addin will function correctly as will a generic WinForms application.

Any advice would be appreciated.

Export to Excel Without Creating File

Hi Forum,

I'm trying to trying to open Excel and populate the worksheet with data without actually saving a *.xlsx a file first from WPF. When the user clicks on save within Excel, he/she should be prompted with file location selection prompt as no file exists.

The closest example I've found so far is Telerik's xlsxformatprovider, which is not exactly what i'm looking for.

Does anyone know how to do this?

Using EventTrigges in GridViewDataColumns

I have to react to a key-down-event in a datacell of a GridView. So in XAML I have defined the following:

<telerik:GridViewDataColumn Header="Bezeichnung" DataMemberBinding="{Binding Bezeichnung}">

<i:Interaction.Triggers>

<i:EventTrigger EventName="KeyDown">

<GalaSoft_MvvmLight_Command:EventToCommand Command=

"{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBox}}, Path=DataContext.OpenNachschlagText}"

/>

</i:EventTrigger>

</i:Interaction.Triggers>

</telerik:GridViewDataColumn>

With this snippet of code there are no errors in the output-console (no "DataContext.OpenNachschlagText not found" or so). But my ICommand (RelayCommand in my case) is not called when I press a key on the keyboard.

What is wrong or better: how can I react on a key, for example the F5 key?

Thanks in advance

Updating A Named Range Programmatically

Hello,

When I update a named range programmatically I am forced to remove the name and re-add it with the updated value. This is fine as a workaround but any cells that referred to the name can have strange visuals depending on the new value. For example, I have a named range 'Test' in which RefersTo is '=1'. I set A1 to be =Test and it displays 1 as expected. If I remove the name and re-add a new name 'Test' with RefersTo '=1000', A1 will extend into the neighboring cell.
