Drop as sibling when DropPosition is AsChildNode

I am using drag and drop to reorder nodes in a treeview, but there are certain rules around where nodes can be dropped and what should happen. I am using a BindingList as the datasource.

The rule that I am trying to support is that a sibling node that has children can be dropped on another sibling that has children, within the same parent. The dropped sibling should not become a child of the target sibling, but it should maintain its original parent (which is the same as the target's parent).

How can I accomplish this behavior?

Thanks for any help.

Gridview Scrollbars

I have a radform which has a menu docked at the top a radstatusbar docked at the bottom and a radsplitcontainer docked to fill, the split container has 2 panels which each have a radgridview docked to fill Since adding a radstatusbar to my form the bottom scrollbars have disappeared. It looks as though the gridview is lying behind the status bar! Do I have to set the size of the grids dynamically to view the scrollbars?

High Dpi message box

Hi

I'm currently designing my application for 1920*1080 screen res which seems to be a popular choice for many hi dpi laptops native resolutions.

I've managed to use some of the code in the forum to good effect and I'm experimenting with the code provided by Ivan Todorov in his useful high dpi article.

If I use the MS message box in my code the dialog size is ok for high res, using radmessagebox I get a reduced size. Can you provide some code or ideas on how to rectify this?

Any other advice or code on adapting to high res screens would be appreciated, although I realise that at the moment there doesn't seem to be a complete solution.

Thanks

Roger

Dropdown event that reacts only to user actions?

We have been using the SelectedIndexChanged event to react to user selections in dropdowns. The problem is that this event also fires when the DataSource is set, when the user is using the arrow keys to browse through the dropdown items, and when different items are selected using AutoComplete. Quite often, changing a dropdown selection can trigger a long and expensive process of database calls and changes to other controls.

I would like to use an event that only fires when the user has truly made a selection. We have been handling this problem by either setting module-level flags to ignore the SelectedIndexChanged event, or temporarily disconnecting the event handler.

Is there a different event that will fire only for actual user interaction? The Windows Forms combo box has a SelectionChangeCommitted event that looks better for this purpose, but I don't see an equivalent event for the Telerik dropdown.

How can I get the number of currently visible Rows in the FilterChanged event handler?
