[Solved] GetDragHintCore is not called

I have a custom VisualItem (class CustomVisualItem : IconListViewVisualItem) and I want a nice image of this item while dragging.
So I wrote this in my VisualItem, but this method never get called (no message in output).

protected override Image GetDragHintCore()

{

Debug.WriteLine("GetDragHintCore");

return GetAsBitmap(Brushes.Yellow, 2, new SizeF(48, 48));

}

Is it a bug or my fault?
Ps: There is pretty much no docu on these to methods (GetDragHintCore and GetAsBitmap [what about the parameters?]).

Combobox Column and Enter Key

Hi,

I've posted about this before, but two days later the thread disappeared, wierd!
Anyway, i have more details now.
I have an app which uses a gridview with a combobox column. the combobox column uses suggestAppend
It seems the combobox column, by default, requires the user to hit enter twice before EndEdit is called.

The grid itself has a custom GridBehavior to override ProcessKey such that when enter is pressed, it calls EndEdit and SelectNextRow
This is so that on the combobox column, the user only has to hit enter once.

this worked on version 2010.2.10.914 of the telerik controls, i am now using the latest version and it no longer works. ProcessKey is never called while the suggestions list is showing.

Is there a way for me to get the KeyPress events from the suggestion box to bubble up to the gridview?

Thanks,
Matt

Design error trying to inherit from base form

Hey Telerik!

We are currently evalutaing your windows forms control suite and have hit a road block. One of our custom controls that we created relies on a base windows form which contains all the drag/drop logic, etc. The other forms then inherit from this base form. This works perfectly with regular windows forms.

When I tried to set up a simple scenario with a base form and have a second form inherit from the base, I am unable to add any controls in the designer and instead am greeted with this design error:

" The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: InheritBase --- The base class 'WindowsApplication1.RadFormBase' could not be loaded. Ensure the assembly has been referenced and that all projects have been built. "

I have uploaded my simple test here : http://www.vbninja.com/baseformtest.zip

Thanks
Mark

Hi,

What is the best way to validate a raddropdownlist? I'v looked at the _Validating Event but this appears to only fire when you select another control.

When I try the selectedvlue_changed this appears to fire when the control is being databound etc.

Any help or pointers would be great.

persisting Bindinglist of Business Objects back to the databse

In this online doc topic: http://www.telerik.com/help/winforms/gridview-populating-with-data-binding-to-bindinglist.html

it shows how to bind a bindinglist of business objects to the gridview. I can see that the ListChanged event can be trapped for insert and delete and changes persisted to the database. my question is: how does one persist edits made in the grid that immeditaly update the underlying binding list back to the database? what bindinglist event should I subscribe to for the update? how do I get the index of the edited row from this event?

Do you have an working example of persisting a gridview/bindinglist back to a database without using a LINQ context or an ORM?

Thanks,
Jonathan

Expression Dark Theme

Is there an equivalent theme in winforms to the "Expression_Dark" theme that comes with the WPF tools?

I have been using Expression Dark for a WPF project and have just started working on one in Winforms and would like to use a theme similar to expression dark.

Are there any other themes out there other than the ones that come out of the box with the controls? I am not a huge fan of the Office 2010 or Telerik Metro or Windows 7 themes that come with the controls.

I am aware that I could use the Visual Style Builder, but currently do not have the time to do so.

Thanks
