When the window is small, the title is not fully displayed

Hello,
look at the two attached screen shots: the Normal image displays the window with a width large enough to display the full title, the Small image displays a window slightly smaller and the Smallest image displays an even smallest window. As you can see, the Small image displays not fully the title, even if it remains plenty of white space; and the Smallest image displays the title left aligned, with missing parts and plenty of empty space at the right.
This is with the Office2013 theme.
Note also that the font for the title is too small.

How to access the Grid Value for RadGridView ??

Hi All
I have a RadGridView in my code of the namespace "Telerik.Windows.Controls.RadGridView". I need to iterate through the rows and get all the data. I am using the code as :
IList<GridViewRow> rows = RadGridView1.ChildrenOfType<GridViewRow>();
foreach (GridViewRow row in rows)
{if (!(row is GridViewNewRow))
{foreach (var x in row.Cells)
{
GridViewCell y = (GridViewCell)x;
System.Diagnostics.Debug.WriteLine(y.Value);
}}}

The value comes as null if the column if is of type checkbox. I need some generic code to get the value.

Anybody any idea about this ??

Office2013 theme: show scroller when not needed

Hello,
look at these screenshots, with the ribbon set to automatically collapse.
WithScroller shows the application with a width set to display a scroller, with large icons.
SlightlySmaller shows the same application, with its width reduced: some icons are sets to medium and the scroller is gone.
It seems that the trigger to have medium icons is set too late.

Misaligned "node lines" in RadTreeView

I'm noticing that some of the "node lines" in my RadTreeView are misaligned by a pixel or two. It doesn't seem to be theme specific, as I see the same issues regardless of the chosen theme.

I've attached an image of the problem. The red arrows indicate a few examples of where the lines are not quite right.

Thoughts?

ContextMenu with CheckBox

Hello,

i'm going to build a RadContextMenu and set the ItemSource with the Columns of a RadGridView.
The task is to show a list of names of columns and a CheckBox in front of them to set the Visibility of columns.
But i can not show the CheckBox in my project.
I followed Binding to Dynamic Data and tried the code in definition of RadGridView like this:

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu Opened="RadContextMenu_Opened" Opening="RadContextMenu_OnOpening">

<telerik:RadContextMenu.ItemContainerStyle>

<Style TargetType="telerik:RadMenuItem">

<Setter Property="Visibility" Value="{Binding IsReorderable, Converter={StaticResource BooleanToVisibilityConverter}}"/>

<Setter Property="Header" Value="{Binding Header}"/>

<Setter Property="Icon" Value="{Binding IsVisible}"/>

<Setter Property="IconTemplate">

<Setter.Value>

<DataTemplate>

<CheckBox IsChecked="{Binding}"/>

</DataTemplate>

</Setter.Value>

</Setter>

</Style>

</telerik:RadContextMenu.ItemContainerStyle>

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

Is there something wrong in my code?
Thank for any help.

Office2013: problem with title bar under Windows 7

Hello,
when using a RadRibbonWindow as a main window with the Office2013 theme under Windows 7, the title bar is almost invisible when over a dark background. Interestingly, the second window opened by the application has its title displayed correctly.
See the attached screenshots.

TextSearch doesn't always highlight found items

I am using the combobox search and I keep finding that the search doesn't necessarily highlight the item that it has found. Often if I hit return, it selects the item and so I can see that it has found it, but I have my combobox set up to have auto dropdown, and I would expect that the item that is found is always highlighted.

Do you have any ideas what I may be doing wrong?

Here is a copy of the one of my GridViewComboBoxColumns:

<telerik:GridViewComboBoxColumn Header="{Loc Material}" MinWidth="80" Width="150"
ColumnGroupName="columnGroupCostType"
IsGroupable="False"
IsFilterable="False"
EditTriggers="CellClick"
ItemsSourceBinding="{Binding Path=Data.DefaultItemCategories.CostTypes, Source={StaticResource bindingProxy}}"
DataMemberBinding="{Binding Path=MaterialCostTypeCode, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
SelectedValueMemberPath="Code"
DisplayMemberPath="Description"
telerik:TextSearch.TextPath="Code"
ItemTemplate="{StaticResource CostTypeComboBoxItemTemplate}"
IsReadOnlyBinding="{Binding Path=IsMaterialCostTypeReadOnly}"/>

Gridview exception when pasting to sorted column

Hi all,

Our WPF application use many GridViews and most of them allows column sorting. Problem: we often get a crash and this error message when pasting data in a sorted column: "Cell is already in the collection".

I know that you have answered similar problems before (see http://www.telerik.com/community/forums/silverlight/gridview/gridview-exception-on-pasting-from-excel.aspx), but none would help me.

We are currently using GridView.dll version 2012.2.725.40. The language is C# and the IDE is VStudio 2010 on Windows 7 Enterprise 64 bits. The WPF application uses MVVM Light.

Thank you in advance!!
