Expand and collapse nested grid with a parent row click

I have a nested grid and I want to expand it and collapse it with a parent row click. It expands with parent row click per default but if i want to close it (collapse it) i have to hold crtl. I want to be able to collapse it again on the parent row click without holding crtl button. How is that possible? Thanks

Asserting on RadComboItem's tooltip is not working as expected.

I tried getting tooltip value from comboitems using AutomationElement, it is giving 'RadComboBoxItem' as value of tooltip in all cases irrespectivie of value in tooltip.

Here is the sample application code:

<telerik:RadComboBox Height="17" HorizontalAlignment="Left" Margin="260,84,0,0" Name="StaticComboCtrl" VerticalAlignment="Top" Width="156" ItemsSource="{Binding}" RenderTransformOrigin="0.494,-1.5">
<telerik:RadComboBoxItem AutomationProperties.HelpText="ItemOne" ToolTip="ItemOne">Item1</telerik:RadComboBoxItem>
<telerik:RadComboBoxItem AutomationProperties.HelpText="ItemTwo" ToolTip="ItemTwo">Item2</telerik:RadComboBoxItem>
<telerik:RadComboBoxItem AutomationProperties.HelpText="ItemThree" ToolTip="ItemThree">Item3</telerik:RadComboBoxItem>
<telerik:RadComboBoxItem AutomationProperties.HelpText="ItemFour" ToolTip="ItemFour">Item4</telerik:RadComboBoxItem>
<telerik:RadComboBoxItem AutomationProperties.HelpText="ItemFive" ToolTip="ItemFive">Item5</telerik:RadComboBoxItem>
<telerik:RadComboBoxItem AutomationProperties.HelpText="ItemSix" ToolTip="ItemSix">Item6</telerik:RadComboBoxItem>
</telerik:RadComboBox>

Below is the code which gets autiomation element from point and gets "HelpText" property from that control.

System.Windows.Automation.AutomationElement testControl = AutomationElement.FromPoint(LocationOfTheCombItem or mouse position);

testing = testControl.Current.HelpText;

Here variable testing is always populated with value "RabComboBoxItem" but not actual value.

Any help would be highly appreciated in this regards.

Refresh RapMap Provider

Hello,

I’ve had issue with RadMap Provider cache in my application. My RadMap is connected to a local WMS (Geoserver). I've changed the map on the Geoserver to hide airport locations but it's not displayed in my RadMap (see attachments).

I have set the attribute "IsTileCachingEnabled = true" to enable tile caching (under %APPDATA%/Local/TelerikMapCache).
Then I added a function to clear the MapProvider when requested by the user :

            if (_mapProviderWrapper.MapProvider is WmsCustomProvider)
            {
                var wmsCustomProvider = (WmsCustomProvider)_mapProviderWrapper.MapProvider;
                var cacheStorage = wmsCustomProvider.CacheStorage as FileSystemCache;
                if (cacheStorage != null)
                {
                    string cachePath = cacheStorage.CachePath;
                    Directory.Delete(cachePath, true);
Directory.CreateDirectory(cachePath);
                }
            }

But even when the folder is empty and that I restart the application, RadMap still display airports which may means that tiles are cached somewhere else.
Is there a way to force a refresh of a MapProvider after the cache has been cleared?

Thanks!

Etienne

PreviewMouseDown event prevents ComboBox from opening

Why would a PreviewMouseDown event prevent the ComboBox from opening?

In using the snippet below and using that event (whether there is any code in the handler or not), the ComboBox will not open. Once the event reference is removed from XAML it works as expected.

What am I missing here?

<telerik:RadComboBox Height="23"

Margin="12,20,12,0"

VerticalAlignment="Top"

DisplayMemberPath="LIST_NAME"

IsEditable="True"

IsFilteringEnabled="True"

IsReadOnly="True"

IsTabStop="True"

IsTextSearchEnabled="True"

ItemsSource="{Binding Path=ElementTypes}"

OpenDropDownOnFocus="False"

PreviewMouseDown="rcb_PreviewMouseDown"

StaysOpenOnEdit="True"

TextSearchMode="Contains" />

AutocompleteBox within EditAppointmentDialog

Hi, I was successfully able to create and populate an autocompletebox using the styles provided in your SDK's for Custom Appointments. But the SelectedAttendees is sort of a dictionary so the setter is never trigger. Any thoughts on how I get around this?

<telerik:RadAutoCompleteBox Margin="6 0"

x:Name="AttendeeAutoCompleteBox"

Grid.Column="1"

ItemsSource="{Binding Path=AdditionalData.Atts, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"

SelectedItems="{Binding Occurrence.Appointment.SelectedAttendees, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

DisplayMemberPath="DisplayName"

TextSearchPath="Search"

Style="{StaticResource MultiAutoBox}"

WatermarkContent="Search ..."

MinHeight="55" VerticalContentAlignment="Top" Padding="5">

<telerik:RadAutoCompleteBox.DropDownItemTemplate>

<DataTemplate>

<Grid Background="#F7F7F7" Margin="0">

<Grid.RowDefinitions>

<RowDefinition Height="Auto"/>

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

<ColumnDefinition/>

</Grid.ColumnDefinitions>

<TextBlock Text="{Binding PersonName}" FontWeight="Bold" FontSize="14"/>

<TextBlock Text="{Binding SubName}" FontWeight="Bold" FontSize="14" Grid.Column="2"/>

<TextBlock Text="{Binding RType}" Grid.Column="1"/>

<TextBlock Text="{Binding SubType}" Grid.Column="3" Grid.Row="0"/>

</Grid>

</DataTemplate>

</telerik:RadAutoCompleteBox.DropDownItemTemplate>

</telerik:RadAutoCompleteBox>


public ObservableCollection<AttendeeSearchDTO> SelectedAttendees 
{
    get
    {
        return this.Storage<CustomAppointment>().selectedAttendees;
    }
    set
    {
        CustomAppointment storage = this.Storage<CustomAppointment>();
        if (storage.selectedAttendees != value)
        {
            storage.selectedAttendees = value;
            this.OnPropertyChanged(() => this.SelectedAttendees);
        }
    }
}

Controls in RadRibbonDropDownButton.DropDownContent

Hello,

I'm using a RadRibbonDropDownButton. Inside, I'm using a RadRibbonDropDownButton.DropDownContent. Inside it, I had put some differents controls.

You can see the begining of my code in '1' attached file.

For example, when I had clicked in a comboBox item, the DropDownContent is closing. But if I click on a radioButton, DropDownContent stays here (is that I want).

Do you know if there is a property who can avoid to close the DropDownContent ?

Thanks you.

Valentin.
