How to highlight and select Drop Target TreeViewItem?

Hell out there!
Maybe sbd. out the can help me. I want to implement a drag and drop operation from RadGridView to RadTreeView. But I am too silly.
So, in GridView DragQuery event, I fill the payload:

private void grdSessions_DragQuery(object sender, Telerik.Windows.Controls.DragDrop.DragDropQueryEventArgs e)

{

e.QueryResult = true;

if (e.Options.Status != DragStatus.DragQuery)

return;

var sessionToDrag = (XTSession)grdSessions.SelectedItem;

if (sessionToDrag != null)

{

e.Options.Payload = sessionToDrag;

e.Options.DragCue = RadDragAndDropManager.GenerateVisualCue();

e.Options.ArrowCue = RadDragAndDropManager.GenerateArrowCue();

}

I also implemented the DropQuery and DropInfo of the TreeView:

private void tvwNodes_DropQuery(object sender, Telerik.Windows.Controls.DragDrop.DragDropQueryEventArgs e)

{

if (e.Options.Payload is XTSession)

{

e.QueryResult = true;

}

private void tvwNodes_DropInfo(object sender, DragDropEventArgs e)

{

if (e.Options.Status == DragStatus.DropComplete)

{

if (e.Options.Payload is XTSession)

{

// Do the stuff

}

My Problem is now, that I have no Idea how to higlight and track the target treeviewitem? When I move the mouse cursor over a treenode in drop mode, I want this treenode to be highlighted. How can this be done? And how can I find out on which node the the drop was done in DropInfo event? The destination object contains the whole treeview. Also, I should disable drop if the mouse cursor is not over a treeviewitem. How can this be done?
Can anybody help me out?

Thanks in advance.

Blend doesn't find default templates

Hello,

When I try to extract a default template of any telerik control in Expression Blend I have only the option "Create Empty" available.
I don't install telerik libraries on my dev computer, but copy the dll's directly into a 3rdParty folder in my solution and use them from there.

Why Blend is not fining the templates, how to fix it?

Thanks,
Tina

when using Timespan as a datatype for filter , listed operator's are only "Equal To" and "Not Equal To". could we customize it to include say "Greater Than","Less Than" etc. similarly while using string as the datatype could we cut down on the operators.

Any help/comments would be appreciated.

Grid bound to Data Table with image URLs

Hello,

we have a Grid with automatic data binding to DataTable object. One of the columns calles "Image URL" contains urls of images on the web. Instead of printing the URLs I would like to load and display images that correspond to it. Here is the code we use

@(Html.Telerik().Grid(Model.dt)

.Name("TheGrid")

.Scrollable(s => { s.Enabled(true); s.Height(600); })

.Columns(col => col.AutoGenerate(c => { c.Width = "150px"; })))

.Sortable(sorting => sorting.Enabled(true))

.Filterable(filtering => filtering.Enabled(true))

.Pageable(paging => paging.PageSize(int.MaxValue).Style(GridPagerStyles.Status))

.ClientEvents(events =>

{

events.OnDataBinding("onResultsGridDataBinding");

})

)

Model.dt is a DataTable object. Please help.

Help Deciding on Control

Hey Everyone

I need help deciding which control would be best for a design I've been given. I need a control similar to a combo box or drop down in that a button on the right will be used to expand the control. However, the content of the control will have multiple items on each line. The attached images should explain a little better. The expanded contents should float over the other controls on the screen; not push them down.

Help!

Thanks
Mark

I know there must be a way to set the font of the page numbers generated by PageField, but I can't figure it out. Also, there are 3 formatting strings, but I can't find any documentation on how they are used.
Thanks,
