RadWindow.Alert - sound?

I'm replacing some calls to MessageBox.Show() with calls to RadWindow.Alert so that the message dialogs match the theme of my application. However, I noticed that the Alert dialog doesn't play any sort of system sound like MessageBox.Show. Digging through the docs and the forum, I don't see any mention of this. I'd definitely think the pre-defined dialogs should have some built-in system sound support., right?

Input appreciated.

Allow edit if new column, and readonly if existing using entityframework

Hello,

I am using Radgridview, and there is a situation.
The gridview is binded to Observablecollection of Entity framework class.
I need to make some of the columns (2-4) readonly if the grid is in edit mode.
If adding new row, the columns should be editable.
I am using telerik:RadGridViewCommands.BeginInsert to add new row.

Note: MVVM pattern is followed.

Regards,
Reyas Mohammed

One menu item needs to change the state (enabled/disabled) of some other items in the menu.

Hello,

I'm using RadMenu in a "C#-WPF-MVVM-Microsoft Prism" application.

I have made a very simple example that reproduces the problem. In this example, I have a "File" menu with two items: "Open" and "Close".
At first, I want the "Open" item to be enabled, and the "Close" item to be disabled since there is nothing to close.

When the user clicks on "Open", the open operation is called via a Prism DelegateCommand.
After this, I want the "Open" item to be disabled and the "Close" item to be enabled.

If you run the example, you will see that now both items are disabled.

3D chart aspect ration question

I just noticed that my 3D chart maintains it's aspect ratio when I resize it's container. I would like to be able to create a 3D column chart that is very wide relative to it's height (The 2D chart does this automatically). I can't seem to do this because the chart won't "stretch" horizontally. I have looked for an appropriately named property & searched the forums to no avail. Am I missing something or is it not possible to change the aspect ratio of a 3D chart?
Thanks - Mitch
