What event is triggered when appointment is moved

I use scheduler to show appointments. The scheduler is not mapped directly to some db table, so I have to handle persistence by myself. For adding and editing appointment I use CollectionChanged event of Appointments and it seems to work, however when the appointment is moved by dragging, the CollectionChanged event is fired with Action NotifyCollectionChangedAction.Batch and I don't know what appointment was changed. Can anybody give me a hint how to handle this situation?

Thank you

Separator on Menu

I'm using a RadMenu and I have added two Separators. How can I give them some type of visual appearance? The separators added a small amount of additional space beween menu items but does not give any type of visual. Do I need to add an image? What I would like to have is something close to "|" display.

Alternative Row Background Colors

I am using the VisualListItemFormatting event to achieve an alternating item background color effect like so:

Private _rowIndex As Integer = 0

Private Sub cmb_VisualListItemFormatting(sender As Object, args As VisualItemFormattingEventArgs) Handles cmb.VisualListItemFormatting

If _rowIndex Mod 2 = 0 Then

args.VisualItem.SetValue(LightVisualElement.BackColorProperty, Color.FromArgb(224, 226, 255))

args.VisualItem.SetValue(LightVisualElement.GradientStyleProperty, GradientStyles.Solid)

End If

_rowIndex = _rowIndex + 1

End Sub

However, this appears to affect the mouse over background color. Here's the default mouseover on a row not impacted by the formatting above (note the entire background is highlighted):

And here's the mouseover on a row impacted by the formatting (note that the background is not highlighted - only a border appears):
http://screencast.com/t/HD2AfEEs

How can I make these consistent? Preferably all of the items would have the entire background color changed. OR, is there a better way to achieve alternating item colors that would not cause this issue?

RadGridView available filter conditions

In my grid, I want to limit the available filter conditions as they don't apply. I am doing so in the ContextMenuOpening event:

Private Sub WorkLogGridView_ContextMenuOpening(sender As Object, e As ContextMenuOpeningEventArgs) Handles WorkLogGridView.ContextMenuOpening

If e.ContextMenuProvider IsNot Nothing Then

e.ContextMenu.Items.Remove(e.ContextMenu.Items.Single(Function(item) item.Text = "Contains"))

e.ContextMenu.Items.Remove(e.ContextMenu.Items.Single(Function(item) item.Text = "Does not contain"))

e.ContextMenu.Items.Remove(e.ContextMenu.Items.Single(Function(item) item.Text = "Starts with"))

e.ContextMenu.Items.Remove(e.ContextMenu.Items.Single(Function(item) item.Text = "Ends with"))

e.ContextMenu.Items.Remove(e.ContextMenu.Items.Single(Function(item) item.Text = "Is null"))

e.ContextMenu.Items.Remove(e.ContextMenu.Items.Single(Function(item) item.Text = "Is not null"))

e.ContextMenu.Items.Remove(e.ContextMenu.Items.Single(Function(item) item.Text = "Custom"))

End If

End Sub

This works correctly. However, note that I am removing the first default item "Contains". Even though it is removed, it is the default condition selected:
http://screencast.com/t/vFv78ZoLE

This shows that the items have been removed correctly:
http://screencast.com/t/tcotptFmN4aK

Ideally I would like either No filter or Equals selected by default instead of Contains.

In addition, I'd like this functionality to be different for different columns. I'm trying to find how to determine which column is applicable in the code above, but am not able to find the needed info. I've also tried to subscribe to the CurrentColumnChanged, ColumnIndexChanged, and ColumnIndexChanging event to stored the selected column but it appears those events do not fire when I click on the filter button.

In other grid when I work with check box column I can set value of checkbox pressing space bar. I tried to set value with space bar but RadGridView have a strange behaviour.

1. on first load on first row press once space bar but grid doesn't check
2. after few seconds press another time space bar and grid check cell
3. go to second row with arrow keys
4. press space bar first time on second row and... check on first row disappear ?!? and on check on second row stay off
5. press space bar second time on second row and appears check on second row
6. go to third row and appers check also on the first row ?!?!?

I want a simple way to set checkbox in column similar Microsoft standard control ListView when set with CheckBoxes = true.

Placed a listview and a radgridview this code can reproduce error and my favourite behaviour.

Thanks in advance,
Emanuele Savarese

Export To PDF locks UI Thread

I am exporting a GridView of about 1500 rows and 20 columns to Excel and PDF. I do both in a BackgroundWorker Thread. The Excel export works fantastic and does not lock my UI. However, the PDF export takes significantly longer and locks my UI thread even though I am running it from a different thread.

What gives?

This is in my DoWork() method. It 'hangs' on the "RunExport()" line.

ExportToPDF pdfExporter = new ExportToPDF(uxResultsView);

pdfExporter.FileExtension = "pdf";

pdfExporter.PageTitle = "Provider Search Results";

pdfExporter.FitToPageWidth = true;

pdfExporter.ExportVisualSettings = true;

pdfExporter.RunExport(fileName);

chartObj.SkinsOverrideStyles = false;

chartObj.ChartTitle.TextBlock.Text = "No of Items";

chartObj.Size = new Size(800, 600);

chartObj.ItemDataBound += new EventHandler<ChartItemDataBoundEventArgs>(chartObj_ItemDataBound);

chartObj.DataManager.DataSource = _objBLL.GetData();

chartObj.DataManager.LabelsColumn = "ColumnName";

chartObj.IntelligentLabelsEnabled = true;

chartObj.DataBind();

chartObj.Series[0].Type = ChartSeriesType.Pie;
