Hello,

Currently I have:

this.radScheduler.ActiveView.AllowAppointmentMove = true;

this.radScheduler.ActiveView.AllowAppointmentResize = true;

However, I don't want to allow users to move an appointment to a date or time in the past.

For example, there is an appointment for 2pm Tuesday. I want to prevent/block a user from selecting that appointment and moving/dragging it to 11am that day, OR to a day in the past (like the previous Friday). Since neither situation makes logical sense.

Is this possible?

Thanks

-Jeremy

Passing a parameter to a table in the tableadapter

Hi,
I have a radchart bound to a SQL table, which contains data for multiple servers. Currently, I have it hard coded to pull info for just one server. Ideally, I would like to be able to set it up so that I can change what server info is being pulled by passing in a parameter and querying for the metrics pertaining to that server. So I'm looking for how to setup the table in my tableadapter to be able to accept a parameter and also once the user sets the parameter how do I send it to the query in my tableadapter.

Thanks,
Jeremy

RadFlowChart

Hello Telerik,

I'd like to put a vote in for a FlowChart product. I've actually seen a few places where you guys have mentioned that you were coming out with one, so I'd like to know if it's still in the works. Our group is likely to pay a good deal for another product, simply to get a FlowChart and I know that it will be much worse than one you guys would put together. Some good news in this area would be wonderful.

Here's a link to a page with some diagrams like what we're looking for: http://www.lassalle.com/products.htm#Layout

Specifically, the ones like the hierarchical layout at the bottom would be great!

Thanks!

Jeremy

Change fill of mimize, window state and close buttons

Let me start by saying I am new to the Visual Style Builder. I have found that the delivered themes have been sufficient in the past. However, my company has recently mandated common UI schemes and therefore it seems easier to create separate theme than to try and manage all applications colors. So with that said...

I have a ShapedForm with a RibbonBar at the top. I want to change the backcolors of the three buttons at the top of the form. I found how to do it, but when I change one, it changes all three. How do I change each one individually? Just as an example (and this is not exactly the case, but) what if I want the minimize button to have green back color, the window state button to have blue and the close button to have red back color. Is there a way to do this?

Also, how do I change the image for these buttons? I have tried clicking on the image for the button, but it will not let me set a new image.

Thanks in advance,

Lee

radTrackBar Value Types

Hi,

Is it possible to get RadTrackBar to progress in fractions rather than whole numbers? (I.e. use double instead of int)

E.g. 0.1, 0.2, 0.3 instead of 0, 1, 2, ..

Thanks,
Brad

.NET Runtime 2.0 Error

Hello,

I've got a problem with an application using Telerik.WinControls.
Every few hours, seemingly random, it crashes with the following error:
EventType: clr20r3 P1: xcat.exe P2: 1.1.0.0 P3: 4aa9aa27 P4: telerik.wincontrols P5: 2009.2.9.701 P6: 4a535c8e P7: 1ac7 P8: 32 P9: system.nullreferenceexception
this error is also logged in windows event log as .NET Runtime 2.0 Error (Event ID: 5000).

From what I understand it's an unhandled NullReferenceException somewhere in Telerik.WinControls assembly.

Using above event data (P7: 1ac7) and windbg I got the following result:
Module: 00988b00 (Telerik.WinControls.dll)
Token: 0x06001ac7
MethodDesc: 04e95348
Name: Telerik.WinControls.RadControlAnimationTimer.Stop()

And than P8: 32 pointed me to the following disassembly line:
L_0032: callvirt instance void [System.Windows.Forms]System.Windows.Forms.Timer::remove_Tick(class [mscorlib]System.EventHandler)

So I think it happens in Telerik.WinControls.RadControlAnimationTimer.Stop() when Tick event hadler is removed (although I'm not 100% sure).

The application does not use RadControlAnimationTimer but I use other Telerik controls (RadGridViews, RadButtons, RadComboBoxes, RadMenus) and they probably make use of the RadControlAnimationTimer.

I also have a try-catch block around Application.Run() but that particular exception does not get caught there - so I can't look at the stack trace to pinpoint where and if the exception originates in my code.

Could you maybe suggest some way of catching that exception or maybe disabling RadContolAnimationTimer.

Regards,

Piotr.

Summary Rows

I need to be able to create a summary column that contains the results of a calculation using other columns in the grid. I understand that you can set the aggregate function for the summary column to none, however, the summary column requires a field name and does not allow an expression. What is the best way to achieve this functionality?

Thanks,

James
