CUIT is not able to access the control placed inside the cell template for RadTreeListView

[Sirisha]

Hi Team,

We are using cell templates for the cells inside the RadTreeListView. In .Net 4.5 and with latest telerik package CUIT is not able to navigate to the controls placed inside the cell template where as in .Net 4.0 we were able to automate actions on it using CUIT.

Following is the sample xaml file code:

<Window x:Class="MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:WpfApplication1"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
     Height="350" Width="525" Title="InterWalmartGraph Cafeteria Grocery Store">

    <Window.Resources>
        <DataTemplate x:Key="ReadonlyTextCellTemplate">
            <DockPanel Margin="1">
                <TextBlock Text="{Binding Count}"/>
                <Button Content="{Binding Name}" />
            </DockPanel>
        </DataTemplate>
    </Window.Resources>

    <Grid x:Name="LayoutRoot" >
        <telerik:RadTreeListView x:Name="radTreeListView"
                            AutoGenerateColumns="False">
            <telerik:RadTreeListView.ChildTableDefinitions>
                <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}" />
            </telerik:RadTreeListView.ChildTableDefinitions>
            <telerik:RadTreeListView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"
                                    Header="Name" />
                <telerik:GridViewDataColumn Header="Count" CellTemplate="{StaticResource ReadonlyTextCellTemplate}" />
            </telerik:RadTreeListView.Columns>
        </telerik:RadTreeListView>
    </Grid>
</Window>

Hi Sirisha,

Thank you for the report. Indeed, there are some problems when .NET 4.5 binaries are used and we are aware of them. Actually, our support for CodedUI was developed for .NET4.0 and unfortunately, Microsoft made a lot of breaking changes with .NET 4.5. That's why incompatibility issues were introduced. We are currently stabilizing our support for .NET4.0 and working closely with Microsoft to address the incompatibility issues with .NET4.5. We hope all the improvements will be introduced with Q2 2014 official version.

Hello Sirisha,

The Q2 2014 official version will contain the fix for the problem resolved in 2014.1.0407 internal build. It is expected to be released next week.

As to the reported exception - from the provided StackTrace it seems there is no Telerik related code, so we are not sure what could cause it. Could you please give us more details on the exact scenario and the exception, so we to be able to research it further?
