The following is my working doughnut chart.

Unable to cast object of type 'System.Windows.Automation.Peers.TextBoxAutomationPeer' to type 'System.Windows.Automation.Peers.SelectorItemAutomationPeer'.     at Telerik.Windows.Controls.RadComboBoxAutomationPeer.RaiseSelectionEvents(SelectionChangedEventArgs e)

Hi,

I am not able to see Telerik RadGridView in my WPF application, I have added resource dictionary in App.xaml,

App.xaml
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/System.Windows.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.Data.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.GridView.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.Navigation.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>

But still I am unable to see RadGridView. I added RabButton and RadComboBox and both of these are visible in the view. I am consuming 2016.1.1013.45 version of Telerik binaries.

The code in my WizardWindow.xaml is,

<Window x:Class="Bentley.CatalogService.DownloadManager.WizardWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="200"/>
                <ColumnDefinition Width="500"/>
                <ColumnDefinition Width="200"/>
            </Grid.ColumnDefinitions>
            <telerik:RadButton Content="Welcome to Download Manager" Grid.Column="0"/>
            <telerik:RadGridView x:Name="RadGridView1" Grid.Column="1"/>
            <telerik:RadComboBox Text="Select One Please" Grid.Column="2" />
        </Grid>
    </Grid>
</Window>

Any ideas?

Have several type of data bound to RadGridView.ItemsSourceProperty, and target cell is in a Not ReadOnly column, how to make cell ReadOnly when DataItem is specified type?

The effect I want is make a column Editable except some cell with specified data type bound to that row, prevent these cell enter EditMode.

I have tried CellStyleSelector, but didn't find IsReadOnly DependencyProperty in GridViewCell.

Also tried using same Template in CellTemplateSelector for CellEditTemplateSelector, but these is no such CellEditStyleSelector, so the cell looks different when enter edit mode.

Thanks.

Using RadGridView in as a Hierarchical grid is it possible to bind the initial parent level and then load any other levels on demand as they are being opened by the user?  If so, does anyone have sample code on how to make this work?  I do not see much in the way of documentation for this in the RadGridView WPF documentation.

With some larger customer datasets our screen is slow at loading all of the data at one time.

Thanks...
