Parts of PDF document (lines, text, etc.) not printing with Q1 2013 version

We have just upgraded to the latest Telerik WPF release (Q1 2013) and now, when printing from the PDFViewer, portions of the right part of the documents no longer print. The document displays fine in the viewer and when saved as a PDF and opened and printed from Adobe, the document prints fine.

I have looked in your documentation for WPF and found this page:Trouble Shooting Common Problems ,but the PrintSettings object used by the WPF version does not implement the ForceVector property. I have also tried using the new PageMargins property of the PrintSettings, but this has no affect on this issue. Does anyone else see the same behavior and/or does anyone have a suggestion?

I have attached scans of the printings. A correct one printed from Adobe and an incorrect one printed from the PDFViewer.

Thanks,
Steve

Runtime Theme

hi.

I am using the "ApplicationThemeManager.cs" from the "RadControls for WPF Q2 2012 Demos".
I called the "EnsureResourcesForTheme" method with these resourses as argument and the theme name.
private string[] resourcePaths = new string[]
{
"Telerik.Windows.Data",
"Telerik.Windows.Controls",
"Telerik.Windows.Controls.Input",
"Telerik.Windows.Controls.Navigation",
"Telerik.Windows.Controls.RibbonView",
"Telerik.Windows.Controls.GridView",
};
every things is working well and all controls changes to new theme (AT RUNTIME) but for the RadWindow and RadRibbonWindow nothing happens (AT RUNTIME).

please do not suggest me to use "StyleManager.ApplicationTheme" or "StyleManager.SetTheme".
just tell me how your sample code is working????

RadDataForm scrolling

Is there a way to disable the RadDataForm's horizontal or vertical scrolling? I've tried this...

<telerik:RadDataForm

x:Name="PartForm"

AutoGenerateFields="False"

CurrentItem="Model"

EditTemplate="{StaticResource PartFormTemplate}"

Header="{Binding Model.PartNumber}"

NewItemTemplate="{StaticResource PartFormTemplate}"

ReadOnlyTemplate="{StaticResource PartFormTemplate}"

ScrollViewer.CanContentScroll="False" />

...(note the ScrollViewer.CanContentScroll="False") and it does absolutely nothing. My LoB form has a grid which, among other things, includes two columns - one with a fixed width and the other with a starred width. The starred width column includes a TextBlock where wrapping has been enabled. I need RadDataForm to allow for disabling the horizontal scrolling so that the text actually wraps.

Ideas? Suggestions?

RadGridView background brush does not update

Hi,

We are using the 2011.1.315.40 version of the WPF libraries.

We have a custom style defined for the RadGridView, and for the background color, we are using a defined brush in another resource dictionary (set as a dynamic resource). From the RadGridView style:

<Setter x:Uid="Setter_302" Property="Background" Value="{DynamicResource TestListBackgroundBrush}"/>

ListBackgroundBrush is defined in two resource dictionaries, with two different values - one for each theme offered by the application. When changing theme, we unload one resource dictionary and load the other.

However, for any RadGridView controls that have already been displayed, the background color does not change. Checking the resources loaded shows that the value with that key has indeed changed - it is just that the RadGridView does not update.

This is strange as the RowStyle for the grid view also has its background set to use this brush (also DynamicResource) and that color does change correctly.

Can you please suggest what could be happening here. It is not an option for use to upgrade to a more recent version of the library.

Thanks.

RadComboBox Isenabled not working

Hello,

I have the following RadCombo Box:

<telerik:RadComboBox x:Name="Combo" Grid.Column="2" Grid.ColumnSpan="4" Grid.Row="0"
VerticalAlignment="Center"
IsEnabled="False"
ItemsSource="{Binding MyList}"
SelectedItem="{Binding selectedItem, Mode=OneWay}"
ItemTemplate="{StaticResource ComboBoxTemplate}"
Command="{Binding SelectedCommand}"
CommandParameter="{Binding Path=SelectedItem, ElementName=Combo }"
/>

Setting IsEnabled to false does not effect the combo box at tall.

If I removed the Command and CommandParameter from the RadComboBox then the IsEnabled Property works as expected.

Is there a way / fix / workaround is use the isenabled property when also using a Command / Command Parameter

Many Thanks

Extending RadTreeView & RadTreeViewItem

Hi,

Purpose: extending the RadTreeView & RadTreeViewItem
In order to immplement the purpose above i had to inherit the both classes.
When i binding the NewRadTreeView ItemSource to viewmodel
i found the previous RadTreeViewItem instead NewRadTreeViewItem.

In order to use my NewRadTreeViewItem i did the override below in NewRadTreeView & NewRadTreeViewItem:
protected override DependencyObject GetContainerForItemOverride()
{
    var rti = base.GetContainerForItemOverride();
    if(rti is RadTreeViewItem)
    {
        rti = new NewRadTreeView();
    }
}

I wonder if i'll have to expect for other things that might affect?
What about the AddItem, Next, Previous etc...?

Best regards
