Is it possible to wrap items in the PanelBar control? We have the following scenario. We want to display three (or more) items on a single line, instead of just one, as is the default. In other words we want to stack the items horizontally. Is this possible?

As of the new Q3 release, one of my grids is virtually unusable because of a style change. I have a grid that has CanUserSelect set to false and IsReadOnly set to true--that way, a user cannot interact with the grid--and it's been perfect. However, in Q3, setting CanUserSelect to false now causes the grid to turn grey and go to a gradient 50% opacity (that's my guess). In any case, my user can barely see the grid now!
Why would you make this change? And if the change was necessary, what can I set to undo it?

Hi!
I´m trying to bind a collection of custom objects to a RadTreeListView. The object represents a `User`, who have a collection of different rights and a collection of log entries.
How can i define the section "Rights/Log Entries" within a HierarchicalDataTemplate? I´ve tried it based on your tutorial on binding collections.
My Version of Telrik WPF is the current public release.
The structure i would like to achieve should look like this:
User 1
Rights
Right 1
Right 2
Log Entries
Entry 1
Entry 2
User 2
Rights
Right 1
Log Entries
...
XAML:

Hi,
Is there any way by which a RadPane's size is set to content i.e. it takes the size exactly to fit the content when it is slide out.
If it is possible, please let me know how.

Hi,
i moved to Q3 of telerik controls, and a piece of code, that worked great in Q2 broke down :
I have a grid, with predefined columns.
The column headers are bound to properties :
i moved to Q3 of telerik controls, and a piece of code, that worked great in Q2 broke down :
I have a grid, with predefined columns.
The column headers are bound to properties :
<telerik:RadGridView >
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn Header="{Binding Dag1}"
UniqueName="test1"
Style="{StaticResource KalenderDagColumnStyle}">
...public MainWindow()
{
InitializeComponent();
this.DataContext = this;
Dag1 = DateTime.Today;
Dag2 = DateTime.Today.AddDays(9);
}
public DateTime Dag1 { get; set; }
public DateTime Dag2 { get; set; }
The KalenderDagColumnStyle is a StyleSelector<local:DatumKolomStyleSelector x:Key="DatumKolomStyleSelector"
WeekdagStyle="{StaticResource WeekdagCellStyle}"
WeekendStyle="{StaticResource WeekendCellStyle}"
VandaagStyle="{StaticResource VandaagCellStyle}" />
<Style x:Key="KalenderDagColumnStyle"
TargetType="telerik:GridViewDataColumn">
<Setter Property="HeaderCellStyle"
Value="{StaticResource KalenderDagHeaderStyle}" />
<Setter Property="CellStyleSelector"
Value="{StaticResource DatumKolomStyleSelector}" />
</Style>
public class DatumKolomStyleSelector : StyleSelector
{
public Style VandaagStyle { get; set; }
public Style WeekendStyle { get; set; }
public Style WeekdagStyle { get; set; }
public override Style SelectStyle(object item, DependencyObject container)
{
GridViewCell c = container as GridViewCell;
DateTime d = (DateTime)c.Column.Header;
if (d == DateTime.Today)
return VandaagStyle;
else if (d.DayOfWeek == DayOfWeek.Saturday || d.DayOfWeek == DayOfWeek.Sunday)
return WeekendStyle;
else
return WeekdagStyle;
}
}
When a column represents Today, it has a style, when its a weekend day, it has a style, and otherwise it has another style
In Q2 c.Column.Header had a value in the SelectStyle method,
in Q3 c.Column.Header is null in the SelectStyle method .
When i hardcode the headers then the value is not null in the SelectStyle method,
but bound values are apparently not available in the style selector
Is this expected behaviour ? is there a way around for me ? ( using Tag instead of Header does not make a difference).
The column headers must be data-bound, because the user can scroll back and forwards in time.
I would have attached a sample solution to this thread; but apparently zips are not allowed

Hello,
can I have different editor types in the same column ? I have a number of items to display in a grid. The value property of these items differs: for some items a combobox should be used to select from a list of possible values, for others a string or number should be entered.
Can I assign different editors to each row in the same column depending on the type of the item bound to that row ?
Thanks in advance,
Lars

We have implemented a search as you type control using the RadGridView. Everytime the text changes we set the ItemsSource to a new source and when data is being loaded the text box is unresponsive. We have specified DataLoadMode="Asynchronous" but it doesn't help. Any ideas?
