I really want to use the RichTextBox in an application I'm finalizing but I have been stymied by the issues I've enumerated below. Firts of all let me provide some background on my particular use so that you can determine if the scenario applies broadly.

Scenario: RichTextBox is used to create Html fragments that are integrated into a finished document where formatting (headings and indents) are adjusted by where the fragment appears in the documents outline hierarchy. Fragments are created as if they are at level 1 (one) and the indent level is programmatically adjusted by where in the outline the fragment appears.

To the best of my knowledge...

1. HtmlFormatter translates Hn tags to <p> tags presents a challengs.
2. Import process defines classes using some sort of internal naming approach. (I'd like associated classes and their name to be retained.)
3. Providing an embedded stylesheet within an imported html document is not used.
4. StyleDefinition(s) do not provide an ability to "name" the definition so that they can be programmatically assigned to a paragraph or span. (There may be a StyleProperty that supports this but I could not determine it.)
5. I was pursueing the approach of wrapping the existing HtmlFormatter object and extending its utilty but many of the underlying classes are exposed at the Friend level versus Public level which prevents this approach

My application is very concerned with **structure** while the RichTextBox is very concerned with retaining **style**. Whle addressing my point 1 above solves all my concerns points 2 - 5 I believe would be of value to other implementers.

I'm going to have to fall back to using the web based Editor (which presents its own set of restrictions) but I will anxiously be watching developments in the RichTextBox as I believe that once finalized it will be an excellent product.

Hi,

Thankful for attention!
  

Hi 

I have an application that has been written over the past 4 years. My company has now purchased RadControls for WinForms and so I am going to slowly convert it screen by screen.

In the meantime though I have a function that is called by all current screens.

SetupScreen(byval frm as form)

I want to do different actions if the form is a Telerik RadForm. How do I know if the frm passed to my function is the standard form or a telerik form? Hopefully without changing the signature of my function "SetupScreen"

Cheers

We Have thread deadlock problem since we upgraded to Telerik 2010.3.
In our application we have a form which is initialized in the background. in some cases, which we can't exactly define the back thread and the main thread lock one each other and the application gets stuck.
The call stack shows that the thread is stuck at Telerik function

We'll appriciate your help as quick as possible.

Going by your examples, I set the AllowDrop for the RadListControl to true. I also have set the SelectionMode to MultiExtended. Also, per your example in the TreeView section, I coded the RadListControl's MouseDown event to call the DoDragDrop() method. However, now I can not select rows with the mouse. I can select extended with the arrow keys and shift key, and I can drag them into the TreeView, succesfully. It's like the mouse only works for Dragging, it won't even control the scroll bar in the RadListControl.

Basically I did everything you wrote in the Treeview "Enabling Drag and Drop" section, except I used a RadListView instead of a Windows listbox for the source control.  It works with a Windows listbox, but I would like to use the Telerik version.

Help Please.

We've bought Devexpress in 2009 and use it all the time.Last week,we found telerik can write WPF-like window form,so we downloaded and tried it to evaluate to buy or not.we found some problem which prevent us from using it. 
     1.when we place a  radtreeview in the form,and click "open property builder", in the RadTreeView Property Builder dialog,we can't see OK,Cancel and Apply button.It seems Property Builder dialog have the same problem.
      2.Sample or demo program have region and language problem.We can't build the demo at first,after changing region and language to english,we can build it.I found there are  many "..." characters [0x85] in the program,which will lead to some problem in other region code.
      we tried it in many computers and  these problems still exist.

I have upgraded to RadControls for WinForms  Q2 2011 (version 2011.2.11.831) from Q3 2010 SP1 (version 2010.3.10.1215)

In Q3 2010, the RadMaskedTextBox supports a right click menu.  In Q2 2011, it does not.

Am I doing something wrong ? (my code hasn't changed).  I noticed that it still does exist on the RadTextBox.

If it was removed (or is a bug), how do I recreate/enable the right click functionality.

Thanks,
Chet

I attempted to reinstall RadControls for WinForms 2001 Q2 (8/31/2011) after being unable to use the designer for the new RadPage controls in Visual Studio 2008. I tried a repair installation; when that didn't work, I uninstalled it completely. Now when I try to install, the installer reports the error:


The installer I'm using is RadControls_WinForms_2011_2_11_0831_dev.msi', located on my desktop.

I've downloaded another copy, thinking the file may have gotten corrupted, but I received identical results the second time. When I tried to select the installer by browsing to my desktop file, I get the error that the installer "is not a valid installation package for the product Telerik RadControls for WinForms Q1 2011", then reference the "_419_dev.msi" file again.

I thought Q2 was out of beta, but I'll install Q1 if it works. What do I need to work around this error?
