[Solved] TabControlHeader cant get focus

Hello,
i try to describe my problem very simple:

- I have a TabControl with CloseButtons in the TabHeader.
- If I open & close a modal window the elements in the TabHeader can't get focus.
- So I can't use the CloseButton in the TabHeader
- After some clicking around the focus available again.
- If I don't open a modal window all elements working great.

When I add some other elements(like a TextBox) to the TabHeader it doesn't work, too.

Thanks for help & sorry for my bad english

(I use Telerik RadControls for WPF Q2 2010 SP2)

Chart AxisX Integer Label Setting

I have a chart where AxisX is a integer sequence that is updated programatically. The problem I am facing is, sometimes I get non integer values (such as 1.5, 2.5.... etc) as lables in addition to Integer labels. I do not want these non Integer labels to appear. How can I do this
1. Through C# code
2. Through XAML

The folowing is the basic code (validations removed) I am using,

private void SetXAxisSettings(RadChart chart, double axisMin, double axisMax)

{

//Update the X Axis

AxisX axisX = chart.DefaultView.ChartArea.AxisX;

axisX.MinValue = axisMin;

axisX.MaxValue = axisMax;

}

and, the following is the static settings I have in XAML

<telerik:AxisX LayoutMode="Between" LabelStep="1" Step="1" AutoRange="False" Title="Batch" />

wpf listbox to gridview ViewModel

I have the scenario where I have a listbox bound to a collection of viewmodels, from which I want to drag to a gridview, upon dropping they will be converted to a second ViewModel and added to the gridviews collection.

I would like to perform these actions in the overall viewmodel itself... the docs state:

Subscribe to the DropQuery and DropInfo events for gridview. You can do that in two ways. The first way is to subscribe in the XAML:

but im afraid im not familiar/smart enough to know what I need to code to subscribe these events to a method or command on the viewmodels?

In the meantime im coding it up with code behind, but I would really like to move these actions to the viewmodels

any help greatly appreciated

[Solved] Hierachical Grid using XAML rather than code behind

I have implemented a hierarchical grid based on the example provided on the Telerik site. This works fine.

However, I am having difficulties binding to properties in my viewmodel from the code behind and the example given seems to bind only to objects in the top level RadGridView's ItemsSource. Although I can continue working in the code behind I would like to see an example of not using the DataLoading eventhandler and sticking with XAML to define the columns for the child rows.

I am unable to find any example of placing the

<telerik:RadGridView.Columns>

or its equivalent section within the ChildTableDefinitions. Surely this must be possible, as these child rows in my case, anyway, contain merely a subset of the columns in the main RadGridView control.

So basically, what I am asking is to be able to do something like the following, where I can handle the table's columns in XAML...

<telerik:RadGridView.ChildTableDefinitions>

<telerik:GridViewTableDefinition>

<telerik:GridViewTableDefinition.Relation>

<telerik:TableRelation IsSelfReference="True">

<telerik:TableRelation.FieldNames>

<telerik:FieldDescriptorNamePair

ParentFieldDescriptorName="BankStatementTranID"

ChildFieldDescriptorName="ParentStatementTranID"/>

</telerik:TableRelation.FieldNames>

</telerik:TableRelation>

</telerik:GridViewTableDefinition.Relation>

<telerik:RadGridView.Columns>

...My XAML column code here...

</telerik:RadGridView.Columns>

</telerik:GridViewTableDefinition>

</telerik:RadGridView.ChildTableDefinitions>

Resize appointment with time interval constraint

Hi Telerik,

When end user resizes appointment's start/end datetime, how can I constraint its time increment interval to, for example 30mins or 1 hour, instead of 1 min interval, so it always "snaps" to the timeslot of the scheduleview?

Thanks,
Cheau

Reversing Display Order of Items...

hey guys,

This one might be pretty simple, but i cant for the life of me work out how to impliment this.

I have a RadTreeView (defined below)

What i would like to do with this is Reverse the order of it, in this example i have 0 - 12 possible controls within my TreeView,

so if i have 4 controls,

1
2
3
4
(is how they are being presented just now)

i want them to display top heavy, so

4
3
2
1

Is this possible? but only on the display, i still want them ordered 1 - 4 in the collection in the code behind? I really hope this is possible!! :)

<StackPanel VerticalAlignment="Top">

<telerikNavigation:RadTreeView HorizontalContentAlignment="Stretch" x:Name="uiActionersList" IsDragDropEnabled="True" DragEnded="uiActionersList_DragEnded"

HorizontalAlignment="Stretch" SelectionMode="Multiple" ScrollViewer.HorizontalScrollBarVisibility="Hidden" dragDrop:RadDragAndDropManager.AllowDrop="True"

IsDragPreviewEnabled="True" IsDragTooltipEnabled="True" SelectionChanged="uiActionersList_SelectionChanged"

ItemsSource="{Binding ActionerModelViewCollection, NotifyOnSourceUpdated=True, NotifyOnTargetUpdated=True,Mode=TwoWay}" Margin="0,0,-5,0" >

<telerikNavigation:RadTreeView.ItemTemplate>

<DataTemplate>

<pmControls:ActionerControl x:Name="ItemsHost" />

</DataTemplate>

</telerikNavigation:RadTreeView.ItemTemplate>

</telerikNavigation:RadTreeView>
