Help File

Hi,

Is there documentation (chm) for the WPF controls? I could not see any in the downloads section, and there's nothing integrated into VS that I could see.

Do users need to peruse Telerik's online documentation for WPF?

Cheers

Marked Zone Label/Tooltip

Hello Telerik Team,

I am using Marked Zones to display certain event timespans in a datetime based chart.

I need to give the user a way to find out what this event what, basically somehow showing a string to him, which can be accessed from any zoomlevel where the marked zone is visible.

Thus, I wanted to use the tooltip-property of a marked zone, but couldn't get it to show. The OnToolTipOpeing event is also not fired.

What is the best way to accomplish this task, to actually present the user a string together with a marked zone?

best regards

Ulrik

Remove flash effect

Hi

when using BusyIndicator on fast running operations you get a flash effect: busyIndicator appears and disappears in a second flashing the user interface. As don't know in advance how long the operation will last, I'm trying to attenuate the effect setting the OverlayStyle completely transparent as follows:

RadBusyIndicator busyIndicator = new RadBusyIndicator();

// make it trasparent to avoid flashing on fast operations

Setter opacitySetter = new Setter(Rectangle.OpacityProperty, 0.0);

Style overlayStyle = new Style();

overlayStyle.Setters.Add(opacitySetter);

busyIndicator.OverlayStyle = overlayStyle; 

// add to layoutRoot children

busyIndicator.SetValue(Grid.RowProperty, 0);

busyIndicator.SetValue(Grid.RowSpanProperty, 3);

layoutRoot.Children.Add(busyIndicator);

I seems that setting OverlayStyle in code has no effect.
What's wrong in the code
A better solution could delaying the control appeareance with an animation effect; how can I do that?

Sincerely
Ivano

RadComboBox select only from the list

Hi,

I use radcombobox with itemSource and I want that the user would select items from the list only and disabled from typing other
characters in it.

In addition, I want that the autocomplete option will be enabled.
I have those properties in my xaml:

<telerik:RadComboBox Grid.Column="3" Grid.Row="6"

IsReadOnly="True" IsEditable="True"/>

but then if the user start type some characterties, he can't delete them.
when I set the IsEditable property to false, it work well, but then it change the control style.

I saw that the first option is working well in the newer telerik dll version, but I don't want to upgrade the all dll. can I upgrade only one control from the new version?
or, how can I change the style of the control that look like IsEditable is true? I use Windows7Theme.
Is ther more idea's or solutions?

Thanks.
