Hi

I'm using the WPF rad control as a print server type application for our silverlight solution (i.e a windows service that prints all completed reports!)

Anyway what I cant workout is how to print a a device other than the default using native printing

I want to open up my report from the DB, check which printer this particular report is to go to and print to it (and a specific tray) without any user intervention

We did this previously with the winforms control txtextcontrol and wonder if you could advice the best way to do with telerik controls

Thanks in Advance

Why does caret drop to line beneath? (Inserting annotation)

Good evening,

Why does the following code force the caret to the line beneath? (obviously you must have multiple paragraphs in your document for this to happen).

In short I'm inserting a Annotation into an empty paragraph. The annotation when inserted does not encapsulate any content (spans etc), it will be filled with content at a later time.

RadRichTextBox radRichTextBox = ((RadRichTextBoxAutoComplete)currentPane).radRichTextBox;

//Set Custom Annotation

ItemGroupRangeEnd rangeEnd = new ItemGroupRangeEnd();

ItemGroupRangeStart rangeStart = (ItemGroupRangeStart)rangeEnd.CreatePairedStart();

rangeStart.Name = "GroupItem " + count++;

//Place annotation around newly inserted text

radRichTextBox.Document.InsertCustomAnnotationRange(radRichTextBox.Document.CaretPosition, radRichTextBox.Document.CaretPosition, rangeStart, rangeEnd);

//Referesh editor

radRichTextBox.UpdateEditorLayout();

It only does it if the following FieldRangeEnd property is set to "false".

public override bool SkipPositionBefore

{

get

{

return false;

}

If I set the return value to "true" then the caret does drop to the paragraph beneath but I don't get other behaviors that I want.

Thank you for your time,

Rob

RadGridView styling when in Popup

Hello,

There seems to be a problem with RadGridView styling when it is placed in a Popup.

I have a Project where I have a RadGridView which has the Items and SelectedItem properties bound to a ViewModel. I create a list of items in the code-behind and put them on the ViewModel, as well as selecting one of those items at random and putting that on the ViewModel to act as the SelectedItem. At run time, everything is bound correctly, and the RadGridView is displayed with the list of items, with the SelectedItem row coloured using the default styling of the orange background.

However, if I put the same RadGridView into a Popup, and introduce a Button which when pressed will allow the Popup to become visible, the orange styling doesn't appear. The RadGridView is still bound correctly to both Items and SelectedItem, but the SelectedItem doesn't get the orange styling, and from a users point of view it looks like nothing is selected.

This only happens the first time the Popup is shown. Assuming the Popup disappears by some event (such as MouseLeave the Popup area), then the next time the Button is pressed, the SelectedItem of the RadGridView will be styled correctly. It seems to be only the first time the Popup is shown, that the orange styling doesn't appear.

I can provide a Project that illustrates this behaviour if required.

Checkboxes not working when using Metro theme

Hi,

I'm unable to get the checkboxes working for my treeview.
I even used the example found in the latest demos, but without result. This is my code;

<telerik:RadTreeView telerik:StyleManager.Theme="Metro"

SelectedItem="{Binding SelectedNomenclatuurnummer, Mode=OneWayToSource}" Margin="10,5"

IsTriStateMode="True" IsOptionElementsEnabled="True" SelectionMode="Multiple" ItemsOptionListType="CheckList" ItemsSource="{Binding Nomenclatuurnummers}"

HorizontalAlignment="Stretch" Grid.RowSpan="4" Grid.Column="1">

</telerik:RadTreeView>

I'm using the Metro-theme. When I change the theme to e.g. Transparent or Office_Black, the checkboxes work

My telerik version is 2012.1.215.35

Any ideas on this?

Styling the axis

I have a chart with DateTimes along the x-axis. I'd like to have those dates respond to application wide time zone changes. I've been implementing this in other places with a multibinding and multivalue converter. I bind the date and the timezone in the multibinding and the converter adds and removes the timezone offset.

Is it possible to do something simlar with the values in the x-axis labels?

QualitativeRange binding doesn't work

Hello,
I am attempting to use a RadVerticalBulletGraph but there is a problem with the QualitativeRange object.I am attempting to implement a BulletGraph in an MVVM pattern such that the ViewModel only needs to provide the Value while the Brush is specified within the XAML (via styling). So my requiements are:

1. QualitativeRange Brush defined in XAML
2. QualitativeRange Value bound to a property on the ViewModel

Unfortunately this appears to be impossible. All working examples I've been able to find either create the QualitativeRange objects in code behind (unacceptable due to the color being defined in code) or have the value and brush hard coded (also unacceptable due to the binding requirement).

If anyone is able to provide an example that meets my two requirements I would be extremely grateful to see it. Thanks,
Jason

RadScheduleView DayViewDefinition to WeekViewDefinition animation

Hello,
I want to disable the animation which shows up when I'm changing dayView (DayViewDefinition) to weekView (WeekViewDefinition).
I tried to disable the animation with Animation.AnimationManager.SetIsAnimationEnabled(this.myScheduleViewUI, false); => does not work.
(I'm using a normal WPF-window)

How can I disable the animation?
Is there even a way to disable the animation?

Plan to support GraphSource TwoWay binding mode ?

I'm testing your new diagram component. Keep up the good work !
This being said, I noticed that an exception raised (InvalidOperationException:"Cannot modify the Items collection when GraphSource is set.") is when I edit my diagram ( copy/paste...) if GrapSource is bound to a datasource.

Do you plan to support this scenario ? It would be very useful.

Rgds,
Robert

Issue -- Tiles maximizing when they shouldn't

Hi,

I have a problem with tiles maximizing as a result from the following steps:

Start in restored state.
User drags a tile from one position to another.
User clicks on the white space within the tile that was dragged.
Tile maximizes.

Is there a way to force the tiles to ONLY maximize when the tile header is clicked?

Thanks
