Hi,

I'm trying to add an appointment to my ScheduleView using:

var appointments = new ObservableCollection<Appointment>();

Appointment myAppointment =

new

Appointment();

myAppointment.Subject = "Appointment Here"

myAppointment.Start = new

DateTime(2012, 7, 31, 00, 00, 00);

myAppointment.End = new

DateTime(2012, 7, 31, 2, 00, 00);

appointments.Add(myAppointment);

scheduleView.AppointmentsSource = appointments;

The above code works, but when I change the End date of myAppointment to myAppointment.End = new DateTime(2012, 7, 31, 24, 00, 00); I'm getting a XamlParseException.

How should I be adding a 24hour appointment? Should it be just myAppointment.End = new DateTime(2012, 7, 31, 23, 59, 00);?

Thanks,
Mark

Is the operators dropdown customizable?

I am using RadDataFilter in the following manner:
Just to build a list of conditions that users can query the database.

Our data is huge and thus we cannot bring all data and let the RadDataFilter control filter it. Rather, we are just using this control to get the list of conditions from the user, and then we query database to get the result set.

So, for example, if an element (column in the database) is of type "string (varchar)", I do not want to see all the options in the operator dropdown. Depending on what element is being filtered, I would want to display only certain operators.

Also, it would be nice to name the operators the way we want to. For example, I want to change the "is equal to" operator to something like "equals", and so on..

How to build a RadDataFilter from the FilterDescriptors ToString value?

I am trying to store the "state" of the RadDataFilter in a database, so that the object can be persisted and the users can add/remove more filter expressions to it.

How is it possible? I tried to serialize the "FilterDescriptors" object, but is it the right way to do it? Is there a better solution than this?

Please let me know.

Mimic Insert Row Behaviour

Hi all,

Is it possible to inset a row in the RadGridView which behaves the same way as the clicking on the insert row.

I also have a context menu with an "Add Row" feature. For consistency I would like it to behave in the same way.

Thanks in advance

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

Customizing "Operator's drop down"

Hi There,

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.

Regards
DEE
