Hello,
When I try to instantiate a new RadGridViewExcelExporter I get a type is not defined error. I have the Interop assemblies referenced and imported as well as:
Imports Telerik.WinControls.Data
Imports Telerik.WinControls.UI.Export
Has the location of the Exporter changed since the documentation was written?

I have a C# Outlook VTSO Add-in project that has issue regarding the behavior of the comboboxcolumn in a datagrid when using the mousewheel. The item just jumps to the first or last item when scrolling using the mousewheel, and also when pressing the up or down arrow while the dropdownlist is visible.
I tried to replicate the issue on a new Telerik C# Windows Forms Application but it seems that the issue only exist for C# Outlook VTSO Add-in projects. What I did was to add a dropdownlist and add more than 20 items and tried scrolling using the mouse wheel on both win form app and vtso addin. The issue only exist on the vtso addin.
Are there any workarounds about this?
Attached here are screen capture of outlook vtso addin and another for telerik windows form.

Is it possible to have a theme for the whole application and a different theme be set with SetTheme for the RadMessageBox? If I set the application theme, SetTheme has no effect. I see how I can override specific controls in your documentation, but the MessageBox is not a form control and, as far as I can see, the only way to set its theme is with the SetTheme function. Can I change the ControlDefault theme to, for example, Breeze, so my forms will automatically use the theme I want for the whole application? If so, how do I go about doing it?

Hi,
Anyone know how to display string as password in RadPropertyGrid?
I've tried to use the PasswordPropertText attribute as the original PropertyGrid, but it is not working.
I hope that telerik still maintain the original behaviour, to keep the control's usage intuitive.
Regards,
Laks

Hi,
I have a solution where a user ​drags data into my application, onto a RadListView. The user drops the data on top of a RadListViewItem representing the subject to added the data to. I have added code for detecting which item that ​was dropped on (from Telerik documentation), but it always returns null from GetElementAtPoint. I have tried other Points (screen, control, client), but it's allways null.
The RadListView is unbound, in DetailView mode and have an icon and two columns. I don't know if that makes any difference in how this is handled.
private void radListView1_DragDrop(object sender, DragEventArgs e){ Point point = radListView1.PointToClient(new Point(e.X, e.Y)); BaseListViewVisualItem droppedItem = radListView1.ElementTree.GetElementAtPoint(point) as BaseListViewVisualItem; if (droppedItem != null) { ListViewDataItem item = droppedItem.Data; // handle dropped data here }}I am using Telerik version 2014.1.226.40.
Best regards
Thomas

Hi!
I have a MDI Ribbon Form. I'm not using ribon merge. My child form open to different sizes. Client requires a single click Cascade sort operatin on all open child windows.
