I have some text in Notepad with paragraphs and the space between paragraph is 2 lines and when I copied same text from notepad or word pad and pasted in RAD Editor, I did not have any space between the parapgrahs, the new paragraph was just started on a new line, no space seperator especially in IE.
When I started adding space between the paragraph from the editor, it added about 5 spaces viually but only 1 when we are done editing. Basically what you see IS NOT what you get.

Thanks,

GridView scroll when dragging item at the bottom of the list.

Dear,

When I'm dragging a row from one GridView to another and I'm at the bottom of the GridView (where I want to drop the row), the GridView won't scroll down (I've attached an image to make the problem clearer).
Is there a property available which enables this or do I need to implement this myself? Just to make sure I don't do extra work :o)

Thanks in advance!

[Solved] Resize row height after scroll / cell value changed

I have a grid view with several columns that have text wrap turned on. AutoSizeRows is on. To set the row heights I am using the workaround described here. This works well for all rows that are initially visible.

1.
However, whenever I scroll down to other rows, the newly visible rows are displayed with incorrect row heights even though their height has been calculated correctly upon cell creation.

2.
Also I am not finding a way to force a row resize after cell contents have changed (e.g. long text entered).

Is there a way to force a row resize, e.g. hooked up to CellFormatting? Is there a timeline for implementing the AutoSizeRows enhancements that have previously been mentioned?

Thanks & kind regards
Frank

Error in Form Designer

I'm working on project with another programmer. After checking out the latest version from source control and attempting to open some of the windows forms in the designer, I get this error:

Could not load file or assembly 'Telerik.WinControls.UI, Version=7.1.1.0,Culture=neutral, PublicKeyToken=5bb2a467cbec794e' or one of its dependencies.The located assembly's manifest definition does not match the assemblyreference. (Exception from HRESULT: 0x80131040)

We are using RadControls for WinForms Q2 2009 SP1 and Visual Studio 2008 SP 1. Any suggestions on how to fix this error?

[Solved] How to reset cell backcolor?

I have a grid with cell backcolor customized in the CellFormatting event (selected cells are highlighted as blue). Once the cells are not selected, I need to return the cell backcolor to its original color. I first tried setting e.CellElement.BackColor = Color.Empty;

& Color.Transparent but this makes the cell as White instead of following the AlternateRowColor. After going through the documentation, I found that I can use CellElement.ResetValue(VisualElement.BackColorProperty). This seems to work better since it respects the AlternateRowColor. However, when I am using some of the Themes, it doesn't respect the ThemeColors. Is there something I am missing?

Binding grid - multithreading mode problem

We are currently writing an application that uses a frequently updated DataTable.

We tried out your grid view to display the data, where we used DataView as binding source.

The nature of the application is to receive continuance updates from several sources, all coming in asynchronic fashion.

The DataTable update is synchronized, and only one thread at a time updates it.

When we are using Windows.Forms.DataGridView control binded to the DataView, it seems to work fine, but when using your control we get an Invalid Index Exception once we try to sort the columns.

The current rate and volume of the updates is about 80 records per source every five seconds, with up to 100 sources, and it is suppose to increase.

Your grid has been tested with three event sources.

Is there any way to update the grid DataSource, DataTable or DataView, in an asynchronic fashion, meaning multithreaded, without having the need to overload the main thread using BeginInvoke ?

Are there any known design patterns for that manner ?

ToolWindow TitleBar text ot displaying properly when docked to a ToolTabStrip

Hi, I am currently evaluating various docking controls for the company I work for and I am very impressed with the RadDock control. I have one small problem, however, that I believe is a bug:

I have a ToolTabStrip that has docked (Fill) inside it a ToolWindow called with a toolwindow: PropertiesToolWindow. PropertiesToolWindow.Text = "Properties".

As I would expect my toolwindow is displayed with the text "Properties" in the title bar and with no tabstrip visible.

Next, I drag another ToolWindow: colourToolWindow (colourToolWindow.Text = "Colour") and drop it onto my ToolTabStrip over NameToolWindow. This Docks (Fill) ColourToolWindow to the ToolTabStrip. The contents of Colour form are shown in the ToolTabStrip area. There is a toolstrip shown with the tabs "Colour" and "Properties". Colour is highlighted. So far so good. Except the title bar still has the text "Properties" where I would expect to see the text "Colour". This happens both at design time and run-time.

Thanks for your help.
