Selecting First Item in the RadListBox on CollectionViewSource.Filter

Hello,
My RadListBox is Binded with CollectionView Source. When I am Changing the Filter it is Automatically selecting the First Item in the Listox.
When I've used simple listBox, I set the property IsSynchronizedWithCurrentItem to False and it helped. But RadLisbBox has't got this property.

Is there any solution for this problem?
thank you

Vertical Column Headers with filter row

Hello,

We are using Telerik for WPF 2013 Q3 NET.
We need to have a vertically oriented text in the grid header row AND a fiter row underneath the header row. The example of what it should look like is attached.

Currently, I set up filter row like so:

<telerik:RadGridView x:Name="trgv"
FilteringMode="FilterRow"
IsFilteringAllowed="True"/>

When I run the app, it looks great. Now, we need to have a text in the header row aligned vertically. For that I do the following:

<telerik:RadGridView x:Name="trgv"
FilteringMode="FilterRow"
IsFilteringAllowed="True">

<telerik:RadGridView.Resources>
<Style TargetType="telerik:GridViewHeaderCell">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="telerik:GridViewHeaderCell">
<ContentPresenter>
<ContentPresenter.LayoutTransform>
<RotateTransform Angle="270" />
</ContentPresenter.LayoutTransform>
</ContentPresenter>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="Height" Value="200"></Setter>
</Style>
</telerik:RadGridView.Resources>

Now, when I run the app, the header text is occupying both the filter row and the header row AND my filters do not appear at all.

Thank you for your help!

Vertical Column Headers with filter row

We are using Telerik WPF controls (2013 Q3 NET) in our desktop application.

There is a requirement for a vertically aligned text in the column headers and also a filter row. (I have attached the picture to this post)

I have tried the following code:

<telerik:RadGridView x:Name="trgv"
FilteringMode="FilterRow"
IsFilteringAllowed="True">

<telerik:RadGridView.Resources>
<Style TargetType="telerik:GridViewHeaderCell">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="telerik:GridViewHeaderCell">
<ContentPresenter>
<ContentPresenter.LayoutTransform>
<RotateTransform Angle="270" />
</ContentPresenter.LayoutTransform>
</ContentPresenter>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

</telerik:RadGridView.Resources>
</telerik:RadGridView>

but when the grid is displayed, the header text spans both header and filter row, and filters do not show up at all.

Can someone help with this issue?

Thank you.

                                <telerik:RadCollapsiblePanel>
                                    <pmControls:ASIRibbonButton Text="Test Button" telerik:KeyTipService.AccessText="TS"/>

[Solved] Lasso selection of data points?

I need to allow users to select multiple points on a ChartView chart by click-and-dragging the mouse, ideally in an arbitrary closed shape (lasso), but minimally in the rectangle formed by the positions of the mouse-down and mouse-up events. Handling the mouse events to define the area, and performing a hit-test on the points should be easy enough for the rectangular case, but I also need visual feedback on the screen showing the shape being drawn.

Are there any examples available showing the best way to accomplish something this with a ChartView? If not, is there anything besides the mouse events I should be exploring, and what's the best approach for the visual feedback aspect?

Thanks,
Louis

Draw Text Tool

I made a custom settings container for my image editor. I am wondering on the draw text tool, how can I bind the properties there to my custom settings UI? Also wondering if I can change the background of the textblock that is displayed? Is there a custom tool demo that closely resembles the DrawTextTool?

Thank you

GridViewDataColumn DataTemplate with DataType is not working

Hey guys,
I've got a problem which is really frustrating. I am trying to display content based on its type in a RadGridView. Therefore I am using a DataTemplate referenced to a DataType. Sadly it seems like the DataType isnt beeing recognized at all. If I change the DataMemberBinding from "{Binding}" to a member of the object which is of type string - it is working but thats not what I need, i need it to be working with my own Data types(classes).

XAML:

<Window x:Class="RadControlsWpfApp1.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

xmlns:local="clr-namespace:RadControlsWpfApp1"

xmlns:System="clr-namespace:System;assembly=mscorlib"

Title="MainWindow" Height="350" Width="525">

<Grid>

<telerik:RadGridView x:Name="Grid" Grid.Column="1" Margin="11,10,9,50" Grid.Row="1" ItemsSource="{Binding}" >

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn IsReadOnly="True" Header="test" DataMemberBinding="{Binding}" >

<telerik:GridViewDataColumn.Resources>

<DataTemplate DataType="{x:Type local:Foo}">

<TextBlock Text="test" />

</DataTemplate>

</telerik:GridViewDataColumn.Resources>

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>
