Exception when set UseGlidingConnector = false

Hello,

when you try to reset the UseGlidingConnector property with a connection attached, an exception is thrown.
How can I (programmatically) find the corresponding connection, detach it from the gliding connector and attach it to a normal connector?
And for Undo-Functionality: how can I re-attach it to the gliding connector when performing an undo?

Different custom tooltips for one appointment issue

Dear Telerik Team!

I use templates for my appointments. There are few of them and each appointment template uses its own tooltip template. When I hover mouse over appointment, correct tooltip is displayed, but if the mouse hovers an edge of the appointment and the mouse cursor changes into resize "mode" (NS cursor), displayed tooltip is incorrect. Is there anything I can do about it?

Very best regards and thank you!

RadGridView gridView = sender as RadGridView;

uPlanning planningContainer = GetPlanningContainer(gridView);

planningContainer.pTimer.Enabled = false;

IList draggedItems = e.Options.Payload as IList;

TreeViewDragCue cue = e.Options.DragCue as TreeViewDragCue;

cue.DropPossibleIconTemplate = null;

cue.DropPossibleIcon = null;

cue.DropImpossibleIconTemplate = null;

cue.DropImpossibleIcon = null;

if (e.Options.Status == DragStatus.DropPossible)

{

int rowIndex = 0;

if (draggedItems.Count > 0)

{

GridViewRow row = this.AssociatedObject.ItemContainerGenerator.ContainerFromItem(this.currentDropItem) as GridViewRow;

DropPosition pos = this.GetDropPositionFromPoint(e.Options.CurrentDragPoint, row);

//azzero template drag&drop

foreach (GridViewRow gvr in gridView.ChildrenOfType<GridViewRow>())

Automatic GUI refres with entity framework

Hello all,
It's my first(?) post so please be forgiving. To be onest the same post I've sent to ScheduleView section :-), so this is quote:

"I've studied ScheduleView with database entity framework (SDK samples).I'm wondering if it is possible to get automatic feedback from database and automatically refresh WPF GUI (ScheduleView) ? In SDK example database is placed in mdf file, but for my needs I've transferred all the tables to SQL Server (Express) - through executing all the sql scripts placed in the ScheduleView Database tutorial. I've modified connectionString to connect with SQL Server instance, instead of database mdf file.
Everything works perfect, but I want to achieve effect in which other person(s) will update Appointments directly in SQL database (e.g. via MS SQL Server Management Studio) and in my application WPF ScheduleView (GridView ?) changes will be automatically visible (e.g. Appointment subiect automatically wil be refreshed). Whether it is at all possible ? I hope all my "problems" are clear to you dear forum people."

Regards
Robert

Error: ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type

Hi,
I'm having some issues using the Gauges: it seems that every element added to the Indicators or CustomItems generates a System.Windows.Data Error. The example in this code

<telerik:RadHorizontalLinearGauge x:Name="EntireGauge" Grid.Row="1">

<telerik:LinearScale Min="0" Max="10" ShowFirstLabel="False" MajorTicks="0" Fill="Green">

<telerik:LinearScale.Indicators>

<telerik:Marker x:Name="PreMarker" Value="3" />

</telerik:LinearScale.Indicators>

<telerik:LinearScale.CustomItems>

<TextBlock Text="CustomItemText" telerik:ScaleObject.Value="5" />

</telerik:LinearScale.CustomItems>

</telerik:LinearScale>

</telerik:RadHorizontalLinearGauge>

cause the following errors:

System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='IndicatorGroup'

System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='TextBlock'

I'm using the version 2012.1.416.40: could you explain me how to fix the issue?

Thank you so much.

Best Regards,
Rocco

Telerik WPF RichTextBox

Hi,

I'm working with the RichTextBox control and I need to change the default alignment of text to justified. How can I do this?
Did some testing, but without success.

Here is the code i am using:

public void SetRichTextBoxSettings(ObservableCollection<Examination> examinations)
{
RichTextBox.HorizontalAlignment = HorizontalAlignment.Stretch;
//foreach (var paragraph in RichTextBox.Document.EnumerateChildrenOfType<Paragraph>())
//{
//paragraph.TextAlignment = RadTextAlignment.Justify;
//}
RichTextBox.DocumentInheritsDefaultStyleSettings = true;
}

Any help would be appreciated.

Best regards,
