hi...

A Callout Control is in your roadmap for winforms please ?

thx in advance...

regards,

Users should be able to use the scrollbars of the container controls at design-time.

RadControls are slow when using at design time in a form containing a lot of controls, split containers and table layout panels

Workaround: manually resize the editor or drag it upwards 

Add the ability to add custom items to the RadPropertyGrid items collection.

To reproduce:
- Add RadLayoutControl to a form.
- Change the Language property at design time.
- You will receive the following message: There is already a command handler for the menu command '1496a755-94de-11d0-8c3f-00c04fc2aae2 : 103'. 

Workaround:
- Reopen the designer.

1. Run TelerikExamplesLauncher.exe - GanttView "First Look" example
2. Scroll and select a task near the bottom, for example: "Send your engagement announcement to newspapers" under "The Guest > 6 Months +"
3. Use splitter to resize between TextView and GraphicalView

You will see that GraphicalView doesn't move but TextView loses task position and scrolls to the top.

Note that using mouse Scroll refreshes the correct position of TextView on the selected task.

Project Update Utility throws unhandled exception when you try to upgrade project which files are not checked-out from source control.

To reproduce: run the sample project, open the test.rtf file and start scrolling with the mouse. As a result, you will encounter the following error:

IMPROVE. RadShortcut - having displayed two forms both using the same shortcut for some action, the shortcut is applied to the first opened form instead to the one on focus.

Setting the SyntaxEditorElement.HorizontalScrollBar.Visibility property to Collapsed indeed hides the horizontal scrollbar but it is still measured and arranged and overlaps the view if you shrink the view:

HI,

Exploring the Demo Winforms FilterView component a bug is present.

When you expand several categories ,the automatic Vertical Scroll bar is showed but the "Maximum"  property value is wrong.

You can't see all the items inside. Some items are hidden at bottom.

But if you collapse some category the new "Maximum" values takes the right previous value before collapsing showing more space as expected

I have a workaround to prevent this situation calling CategoryExpandedChanged event.

Firstly I need to call Application.DoEvents() in order to resizing internally by the component all the StackLayoutPanels connaining the Category Items 

After that, I call the private method UpdateScrollBars (Suggested by support) and the ScrollBar takes the right size for its content.

Now I can show all the contained items inside the FilterView panel.
