Copying appointments (between resources)

Hello!

I've been wanting to implement a copy function for appointments but I can't get it quite right.

The idea is simple, you have a form with a scheduler, which views multiple resources. When you start dragging and keep the control key pressed, you don't actually move the appointment but you copy it.

My code looks like this:

void rdSchedule_AppointmentDropping(object sender, AppointmentMovingEventArgs e)

{

if (ModifierKeys == Keys.Control)

{

if (e.Appointment is AmfAppointment)

{

AmfAppointment copiedAppointment = ((AmfAppointment)e.Appointment).Copy();

copiedAppointment.Start = e.NewDate;

this.rdSchedule.Appointments.Add(copiedAppointment);

e.Cancel = true;

}

rdSchedule is the Scheduler control.

AmfAppointment is my own inheritance of an Appointment and Copy() is a function to duplicate the Appointment.

This only (seems to, still some bugs to work out) work for copying an appointment to the same resources.

When dragging the appointment to another resource nothing happens.

Also; the AppointmentMovingEventArgs has a NewDate but no NewResource (i.e.)? And the e.Appointment.ResourceId is the old ResourceId so I can't get it from there either.

What is the right approach here? And if so how can I make this work for copying between different resources as well?

Thank you!

Required Validator for Bound DropDownBox

Hi, this is my second post about this since my first was not answered and then I guess removed.

I am using MS Visual Studio Professional. The code is ASP.net. I am using Telerik's RadGrid (latest versions I assume, I don't know how to tell..)

I am trying to add a Required validation to a bound Drop Down Box in the RadGrid. I am thinking my problem is a syntax issue because I can get it to work for a regular text box, but the dropdown box just does not work.

This is the code I use for the textbox which works (trying to use the code block format):

Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated

If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then

Dim item As GridEditableItem = TryCast(e.Item, GridEditableItem)

Dim editor As GridTextBoxColumnEditor = DirectCast(item.EditManager.GetColumnEditor("CurrencyTarget_NativeCurrent"), GridTextBoxColumnEditor)

Dim cell As TableCell = DirectCast(editor.TextBoxControl.Parent, TableCell)

Dim validator As New CompareValidator ' RequiredFieldValidator()

editor.TextBoxControl.ID = "NCReqValidator"

validator.ControlToValidate = editor.TextBoxControl.ID

validator.Operator = ValidationCompareOperator.GreaterThanEqual

validator.ValueToCompare = "0"

validator.ErrorMessage = "* Native Current is a required field"

cell.Controls.Add(validator)

End If

End Sub

But when I add the same code for a drop down box, it does not work:

Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated

If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then

Dim item2 As GridEditableItem = TryCast(e.Item, GridEditableItem)

Dim editor2 As GridDropDownListColumnEditor = DirectCast(item2.EditManager.GetColumnEditor("ddCountryCode"), GridDropDownListColumnEditor)

Dim cell2 As TableCell = DirectCast(editor2.DropDownListControl.Parent, TableCell)

Dim validator2 As New CompareValidator ' RequiredFieldValidator()

editor2.DropDownListControl.ID = "CCReqValidator"

validator2.ControlToValidate = editor2.DropDownListControl.ID

validator2.Operator = ValidationCompareOperator.NotEqual

validator2.ValueToCompare = "XXX"

validator2.ErrorMessage = "* Country Code is a required field"

cell2.Controls.Add(validator2)

End If

End Sub

Basic Radgrid Cell Manipulation

Hello,

I was going through the course documentation and searched through the forums a bit but can't find anything telling how to do basic cell manipulation of the radgrid (which means I probably overlooked something or this is so basic, it's not covered).

So, if in vb.net I wanted to move something from column 1 row 4 to column 2 row 5 of a grid we'll call "VoltageGrid", is there an easy command to do that? Do I have to give each cell a unique name in order to do this? I know in basic gridview (the standard grid), it would look like this:

VoltageGrid.Rows.Item(2).Cells(5).Value = VoltageGrid.Rows.Item(1).Cells(4).Value

Could someone let me know a) how to do this and b) where I can find this info so I don't have to bug anyone with basics of these grids? I can go back to using just the standard vb.net but it sounds like there are a lot of good features in telerik's grid. I just need to learn how to use them. Thanks!

-Jay

Difficulty replicating timeline sample...

I want to relipcate the look and feel of the timeline controls as shown in this section of the product documentations...

http://www.telerik.com/products/winforms/scheduler.aspx#custom-resources-and-resource-grouping

However, using the examples on how to load data in when grouping by resources, but editing it so I can get it working as I want, it fails to load. I have been through my code and can't see anything wrong with however?

If someone can let me have a working sample of how to layout the schedule as shown in the example above, or point out where I'm going wrong, I'd be really grateful!

Schedule.ActiveViewType = Telerik.WinControls.UI.SchedulerViewType.Timeline;

Schedule.GetTimelineView().ResourcesPerView = 8;

Schedule.GroupType = GroupType.Resource;

SchedulerDayViewGroupedByResourceElement headerElement = Schedule.SchedulerElement.ViewElement as SchedulerDayViewGroupedByResourceElement;

Resource resource;

resource = new Resource();

resource.Id = new EventId("AC00-1");

resource.Name = "AC00-1";

resource.Color = Color.Beige;

Schedule.Resources.Add(resource);

resource = new Resource();

resource.Id = new EventId("AC00-2");

resource.Name = "AC00-2";

resource.Color = Color.PowderBlue;

Schedule.Resources.Add(resource);

resource = new Resource();

resource.Id = new EventId("AC00-3");

resource.Name = "AC00-3";

resource.Color = Color.PowderBlue;

Schedule.Resources.Add(resource);

Schedule.Appointments.BeginUpdate();

Appointment appointment;

appointment = new Appointment(new DateTime(2011, 12, 07, 12, 00, 00), new DateTime(2011, 12, 09, 12, 00, 00), "Summary", "Descriptions", "Location");

appointment.ResourceId = this.Schedule.Resources[0].Id;

appointment.BackgroundId = (int)AppointmentBackground.Important;

appointment.ToolTipText = "This is my custom Tooltip";

Schedule.Appointments.Add(appointment);

Inserting an image into richtextbox table

Hi,

I looked at the documentation article:
http://www.telerik.com/help/winforms/richtextbox-features-document-elements-tables.html
to get started.

I am battling to place an image into a cell.

To insert an image into the richtextbox is used:

Dim i1 As New Bitmap(fullfilepathtopicture) 'where fullfilepathtopicture is already a string of the full path and filename

Me.RadRichTextBox1.InsertImage(i1)

Now if I want to insert an image and text into a picture in a table as follows I am battling:

It should look something like the attachment

Any help would be welcome.

Treeview doesn't update

Hi there,

i have a MDI-Application with one window which contains a TreeView.
When loading the Window, I do the function FillUserList() and it works fine.
But if I try to update th elist after that, it failed.
This is my code for loading the data:

rtvUserList.DataSource = null;

lsmu = RfcCalls.GetListOfMainUsers();

rtvUserList.DataSource = lsmu;

rtvUserList.DisplayMember = "DisplayValue\\DisplayValue";

rtvUserList.ValueMember = "Uname";

rtvUserList.Name = "DisplayValue";

rtvUserList.ChildMember = "SIPMainUser\\Subuser";

rtvUserList.ClearSelection();

I debugged it and my data is like it has to be.
I tried a Refresh() but that also doesn't work.

Any hint.

Best Regards
Manfred
