getting SelectedItem on MouseRightButtonDown or when openning the contextMenu

Hi,

We have a problem with getting the SelectedItem of the RadTreeView
when we right clicking it to show it's ContextMenu.

the solutions that are presented in the posts are both written in the code behind
and involve an explicit casting to a RadTreeView / RadTreeViewItem in order to
get the SelectedItem.

We are looking for a solution where there is no need to use this code in the code-behind:
http://www.telerik.com/community/forums/wpf/treeview/right-click-to-select-item.aspx
as in Syncfusion there is a property: IsSelectOnRightMouseClick that does that.

We are also looking into avoiding mentioning 3rd-party controls in our ViewModel,
in our Syncfusion mockup we are able to produce this handler:

       void OurTree_MouseRightButtonDown(object sender, System.Windows.RoutedPropertyChangedEventArgs<object> e)
        {
            SelectedItem = e.NewValue as OurSpecificObject;
        }

is it possible to do this with telerik?

thank you.

Support For Multiple Rich Text Boxes with RadRibbon

hey guys,

not sure if this belongs on this forum OR the RadRibbon forum, but its the RichTextBox that i'm most interested in, basically the problem we have, is i have a list of 0 - N controls we call these ActivityControls, each Activity has a TWO RichTextBox controls,

So I have a Ribbon control to control my list of controls, with a Contextual Tab for the Text and Table Controls (taken from the telerik demo)

Is it possible for this singular set of controls to control potentially hundreds of RichText Controls?

If you have a demo of this functionality that'd be brilliant!

Cheers
Regards
Kevin.

Selected Item not displayed

When displaying "Name" from button collection, selected item is not displayed.
It looks pretty straight forward but I can't think of why it won't work.. hmm..
Is this a telerik bug?
The following code shows two different methods, "DataTemplate" and "DisplayMemberPath"
I appreciate for your help.

ItemToolTipOpening and getting Chart instance

How the heck does one get to owner Chart instance from ItemToolTipOpening event? And why on the earth didn't you use normal event definition - sender instead of tooltip - you could pass tooltip instance within ItemToolTipEventArgs ?

Remove CarosoulItemsControl buttons?

I'm trying to get a skinny Carousel working, about 30-or-so pixels high. I tried wrapping RadCarouselPanel in a ListView, but found I had no easy way of accessing SelectedItems.

I'm back to mucking with a RadCarousel to house it all, but those buttons are driving me crazy. Is there an example of using the RadCarousel that does not have the four buttons (page up, moveby, etc)? The only examples I see without the buttons are simply not using the RadCarousel.

Any help would be greatly appreciated

Hierarchical Grid support for Automation

Hi,

I have been using 2 level Hierarchical RadGrid (ver 2010.2.0924) for my application. On running the automation tool (like UI Spy), tool does not able to detect the 2nd level of Grid. It only detects the first level of Grid. I have given the AutomationId for both the 1st level as well as for the 2nd level. Here is the xaml of the defined 2 level hierarchical grid.

<telerik:RadGridView Name="EntitlementGrid" AutomationProperties.Name="EntitlementGrid"

IsReadOnly="True" ColumnWidth="*"

telerik:StyleManager.Theme="Windows7"

ItemsSource="{Binding EntitlementsVM.SelectedEntitlements}"

IsFilteringAllowed="{Binding EnableFilters}"

ScrollViewer.VerticalScrollBarVisibility="Visible" SelectionMode="Extended">

<telerik:RadGridView.ChildTableDefinitions>

<telerik:GridViewTableDefinition />

</telerik:RadGridView.ChildTableDefinitions>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn MaxWidth="30" Header="" IsFilterable="False" >

<telerik:GridViewColumn.CellTemplate>

<CheckBox HorizontalAlignment="Center" VerticalAlignment="Center" IsChecked="{Binding IsChecked, Mode=TwoWay}"

ClipToBounds="True" Padding="1"/>

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn DataType="{x:Null}" Header="Entitlement Id" UniqueName="EntitlementId" />

<telerik:GridViewDataColumn DataType="{x:Null}" Header="PO" UniqueName="PO" />

<telerik:GridViewDataColumn DataType="{x:Null}" Header="SO" UniqueName="SO" />

<telerik:GridViewDataColumn DataType="{x:Null}" Header="Type" UniqueName="Type" />

<telerik:GridViewDataColumn DataType="{x:Null}" Header="Total" UniqueName="TotalCount" ToolTip="Total Count" />

<telerik:GridViewDataColumn DataType="{x:Null}" Header="Available" UniqueName="AvailableCount" ToolTip="Available Count" />

<telerik:GridViewDataColumn IsFilterable="False" DataType="{x:Null}" Header="Requested" UniqueName="RequestedCount" ToolTip="Requested Count" />

<telerik:GridViewDataColumn IsFilterable="False" DataType="{x:Null}" Header="Remaining" UniqueName="RemainingCount" ToolTip="Remaining Count" />

</telerik:RadGridView.Columns>

<telerik:RadGridView.HierarchyChildTemplate>

<telerik:RadGridView Name="EntitlementFeaturesGrid" AutomationProperties.Name="EntitlementFeaturesGrid"

IsReadOnly="True" RowIndicatorVisibility="Collapsed"

IsFilteringAllowed="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:RadGridView}, AncestorLevel=1}, Path=IsFilteringAllowed}"

ItemsSource="{Binding EntitlementItems}"

telerik:StyleManager.Theme="Windows7"

ColumnWidth="Auto">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Feature Name" DataMemberBinding="{Binding ProductName}" />

<telerik:GridViewDataColumn Header="Feature Desc" DataMemberBinding="{Binding ProductDescription}" />

<telerik:GridViewDataColumn Header="Total" DataMemberBinding="{Binding Total}" />

<telerik:GridViewDataColumn Header="Available" DataMemberBinding="{Binding Available}" />

<telerik:GridViewDataColumn Header="Requested" DataMemberBinding="{Binding Requested}" />

<telerik:GridViewDataColumn Header="Remaining" DataMemberBinding="{Binding Remaining}" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</DataTemplate>

</telerik:RadGridView.HierarchyChildTemplate>

</telerik:RadGridView>

Also, i downloaded the trial version of RadGrid (ver 2011.1.0419.35) but this too displays the same behavior. Is there some settings taht I am missing to get the 2nd level of gird detected in the automation tool ?

Appreciate response.

Mustansir.

SplineUnexpectedBehavior

Hi,
I'm working with RadControls for WPF Q1 2010, released on 22 April 2010.
I have a Spline chart bound to a list of objects with a DateTime and an Int value. The Values are plotted correctly using LineSeries, however I ran into a problem using SplineSeries.

If there is no data point for a long time, the chart shows unexpected behavior at the ends of long period as highlighted in the attached illustration. This is unwanted as the X axis represents Time and as it is impossible for time to get back this misrepresents the data. It seems to be a bug from Telerik Chart in such conditions.

I'd like to find out if there is a setting or later release that prevent this behavior. I hope someone can tell me what is wrong!

Generally, I get the following error: xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">

Am I forgetting a using somewhere?

Thank You,

RadButton EventSetter Help.

Hello,

I have a list as a datasource for my Combobox. Whenever the DataSource has an empty value my data trigger inserts the template seen in XAML below. This works perfectly and inserts my separator and radbutton into the combolist as a comboboxitem.

<ComboBox Name="cmbo_NewSME" SelectedValue="You can begin typing the name here..." Height="25" Width="300" Margin="5,6,5,0" Loaded="cmbo_NewSME_Loaded" SelectionChanged="cmbo_NewSME_SelectionChanged">

<ComboBox.ItemContainerStyle>

<Style TargetType="{x:Type ComboBoxItem}" BasedOn="{StaticResource {x:Type ComboBoxItem}}">

<EventSetter Event="PreviewMouseLeftButtonDown" Handler="PreviewMouseLeftButtonDown" />

<Style.Triggers>

<DataTrigger Binding="{Binding Path=AD_FullName}" Value="">

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="{x:Type ComboBoxItem}">

<StackPanel Name="FullUsrListWrap" Visibility="Visible" Width="300">

<Separator Name="FullList" Margin="0,10,0,5" Height="10" Width="300"/>

<telerik:RadButton Name="ShowAllUsrs" Width="220" Height="20" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" HorizontalAlignment="Center" Margin="0,0,0,5" Content="Show All Authorize-IT Users..." />

</StackPanel>

</ControlTemplate>

</Setter.Value>

</Setter>

</DataTrigger>

</Style.Triggers>

</Style>

</ComboBox.ItemContainerStyle>

</ComboBox>

The problem is that I am unable to handle any RadButton events. As you can see above the EventSetter is at the combobox level and while this works I have to first decipher if the person actually selected a username or the "Show More..." button. So I experimented and thought about an EventSetter at the Radbutton level but I keep getting an error.
Everything is same as above except:

<ControlTemplate TargetType="{x:Type ComboBoxItem}">

<StackPanel Name="FullUsrListWrap" Visibility="Visible" Width="300">

<Separator Name="FullList" Margin="0,10,0,5" Height="10" Width="300"/>

<telerik:RadButton Name="ShowAllUsrs" Width="220" Height="20" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" HorizontalAlignment="Center" Margin="0,0,0,5" Content="Show All Authorize-IT Users...">

<Style>

<EventSetter Event="Click" Handler="Click" />

</Style>

</telerik:RadButton>

</StackPanel>

</ControlTemplate>

I keep getting the property Content is set more than once.....but it isn't or I'm overlooking something VERY obvious.

So the error aside what I am after is handling the button click event which may or may not be possible cause it's "disguised" as a ComboboxItem....??

Thanks
JB
