Hello

All the other themes are working properly, only the Vista theme is not working.
I can supply the xaml taht I'm using if necessary, but I'm not doing any styling at all, just taking the stylemanager's theme.

Hi to all,
i just would like to drag a RadTreeViewItem on a different component without make it selected.
Right now i have tried different ways without success...
I have implemented the PreviewMouseLeftButtonDown handler when the item is prepared, so when the user just press down the mouse i store the treeviewitem and put the e.Handled = true just to leave it unselected. When the event PreviewMouseLeftButtonUp is fired i will get the stored element and make it selected (so no drag operation...just a normal click on the element).
The big problem is that the
is sent different times..the first time the source is the "root" element of the RadTreeView the second time the first child of the root element and so on. I think it is not correct to fire so many events if i mouse down only on one RadTreeViewItem...i aspect to have directly on the first event the right treeviewitem on the source!
Do you have any idea how to implement this scenario?
Really Thanks.
Diego Bonura

I'm having issues with AlternatingRowStyle not being applied as
expected when adding or removing items to the underlying
ObservableCollection to which the grid is bound via the ItemsSource
property.
The grid is sorted such that the newly added items are always at the top and the AlternationCount is set to 2.
When adding a second item, the rows display as expected, but when a third item is added, all rows display with the default style. Removing an item from the list does not cause the other rows to adjust based on their new position.
If I Commit an Edit to a cell in the grid, all rows in the grid will update their style and display as expected.
What could cause this kind of behaviour and how do I fix it?

I just got new direction orders from our CIO. He wants to shift from ASP.net application to a smart client application. I have read about the The Telerik CAB Enabling Kit. Does Telerik have a whitepaper or example code that demonstrates best practices for OpenAccess, RIA Dataservices/ Web Services and WPF? I am trying to decide on the approach to take with smart client. I would like any suggestions as to the best way to implement such an application.
Thanks,
Bryan

i want to use checkboxes instead of ctrl+click to select multiple rows in the radGridView. I use this.radGridView.SelectedItems in my functions but i don't know how to use the SelectedItems list with the checkboxes. I would greatly appreciate an example of use.. Sorry for my newbie question, and thank you for the help.

Hello,
There's probably an easier way to add a column to the grid dynamically but it gave me , a newbie, a lot of grief.
Adding a column dynamically to a grid that's associated with a datatable turned out to be relatively easy:
// Create the datatable column
newColumn = new DataColumn();
newColumn.ColumnName = <column name>;
newColumn.DataType = ..
....
<Datatable name>.Columns.Add(newColumn);
<Dataset name>.Tables[0].Columns[<column name>].SetOrdinal(<Position of the new column within the datatable>);
// Break and re-establish the link between the grid and the datatable.
<Grid name>.ItemsSource = null;
<Grid name>.ItemsSource = <Datatable name>;
// Load the new column with data by adding the data to the datatable
<datatable name>.Rows[<row index>][column index] = <data>;
<grid name>.Rebind;
