Is there a way to copy/export the data in a GridView without applying DataFormatString? We have custom formatting on some values and when pasting the values in Excel it's not able to parse them correctly.

I guess that the issue lies in Excel, but a value that is displayed in the RadGridView as "2 250,00" (DataFormatString = "N2", Swedish culture) is parsed as a String when pasted to Excel, and it's impossible to apply any other format until I remove the thousand separator (even when Excel is using a format with a thousand separator).

We're currently copying to the clipboard in Html-format, because some cells contains text with linebreaks, and this seems to be the only way to keep them without breaking the rows.

 

The image I'm working on has some metadata because of which the landscape photo is displayed portrayed. User can rotate once loaded, but what I'm trying to achieve is load the image with proper orientation in first place. I have tested my C# code to read the metadata orientation of image and correct it accordingly to load it properly in normal WPF image control. But I'm having problem using the same code in the Telerik RadImageEditorUI. Basically, I'm looking for an event that could be raised when user selects open>select image from radImageEditorUI dialog box, which then I can use to handle the orientation handling code. 

So, my question is, is there something in Telerik RadImageEditorUI that can handle the orientation issue when loading image? or Is there some kind of image loading or image selected event raised?

    

My software occasionally triggers the exception below. I'm not sure how to catch it or prevent it. Any ideas? I'm using version 2013.2.812.40.

I created a custom diagram shape style that has the content presenter above the shape. The shape looks great until I select it or attempt to create connections to it. I want the selection box only around the shape and not the text. The connectors are also not attached to the connection points on the shape. I have included some images of the issues I am seeing. I assume it has something to do with modifying the manipulation adorner to target the shape within the DiagramShape rather than the entire DiagramShape.

i'm using richtextbox for displaying html and when i got text with 500k char the system stuck for 40 minutes, with 100k it took 3 minutes, with 10k it took 3 seconds
is there anything to do with the performance? is it known issue?
except trimming the text is there anything else to do?

I'd like to place additional content to *left* of a standard, top/left aligned set of tabs. I know that RadTabControl offers an AdditionalContent property, which allows me to specify the necessary content, but it always places that content on the far-right edge of the tab strip. How can I shift that to the left edge of the tab strip?

Hello,

When I use RadScheduleView in visual studio designer, the following exception appears and I cannot visualize control at design-time:

(Note all is fine at runtime).

Any Idea ? Tanks a lot !

When I select multiple shapes in my RadDiagram and execute the Delete command, I expect two events to fire: 

RadDiagram.ItemsChanging and RadDiagram.ItemsChanged.

In each event, I expect e.OldItems to contain all shapes that are being deleted.

Instead, I get individual event: first ItemsChanging and then ItemsChanged for every individual item in my selection. e.OldItems contains a single object every time.

Is this expected behavior? If not, what might I be doing wrong? Getting the shapes in individual events is bad because it doesn't allow me to prioritize the order in which I operate on each shapes. And because ItemsChanging and ItemsChanged fire for each shape until the next one happens, I can't easily cache all the changing items and THEN operate on the whole collection, either.

HI ,

I am using property grid with multiple sections. I would like to sort the categories with my preference (not alphabetically or not default). How can i do it?

Hi,

I would like to define shifts which would start from noon (12pm-12pm), so basically 1 shift would be part in one day, and part in outer day, (minimum shift/appointment duration should be 24h) but would also like to preserve regular day header above it. Please take a look at the screenshot attached. It explains it much better than I could explain it. Is it possible to achieve something like this?

 

Thank you for you help!
