Tooltip: open automatically and click event

Hi all,
I have in a WPF form a RadMap control. Normally for show the tooltip information I have to click on every pushpin.
Is it possible to open automatically all the pushpin's tooltip?

Another question...
Is it possible to click inside the tooltip for open another form?

thanks in advance!!!

var pin = new Pushpin { Background = new SolidColorBrush(colore) };
var tip = new ToolTip { Content = tool };
ToolTipService.SetToolTip(pin, tip);
var loc = new Location { Latitude = lat, Longitude = lon };
MapLayer.SetLocation(pin, loc);
informationLayer.Items.Add(pin);

Databinding in XAML

I have looked all over and I cannot find a single example of how to databind an ObservableCollect to a RadChart. I would like to be able to create 3 series and bind each one of them to a different ObservableCollection. Binding through XAML would work best in my case because my application is written using the MVVM.

Does anyone have an example they can point me to?

How can I dynamically add dataobject to childgrid

I'm using the radGridView and it's hierarchy feature. Because of large amount of data, I fetch data first to the upper/first layer of radGridView with empty sub data object to provide +-mark of beginning of each row (identify that there are sub data available). I'm using the Radgridview.ItemsSource property to add data to the grid.

But now I have problem when expanding one of the row and dynamically add the dataobject to the selected childgrids.itemssource, it's not showing. I'm using following code to add data to the selected childgrid

private void alarmsTbl_DataLoading(object sender, Telerik.Windows.Controls.GridView.GridViewDataLoadingEventArgs e)

{

GridViewDataControl dataControl = (GridViewDataControl)sender;

if (dataControl.ParentRow != null)

{

AlarmsServiceReference.AlarmDetails[] groupDetails = alarmsClient.GetAlarmGroupDetails(alarmsTableDef.DBType, alarmsTableDef.ConnectionString, sql);

dataControl.ItemsSource = groupDetails;

}

How I can dynamically add dataobject to the expanded childgrid?

Chart Export

Hi,

I am displaying a line chart on the screen. It looks great but after exporting to a PNG file, the exported chart does not look anything like the one on the screen. I am disabling the animation as well. Is there anything else I need to be doing to get an exact match?

btw, I was not able to attach the images to show you the differences.

Thanks

A few questions

I'm considering the purchase of Q2 2011 specifically for this control as I'm hoping it will take some of the time and effort out of working with hand-coded ObservableCollections to interact with our WCF service.

I downloaded the trial and it installed fine (other than not installing any of the controls in the VS tool box like it's supposed to). After dragging the control into the window and trying to do a test build I get "The tag 'RadDataServiceDataSource' does not exist in XML namespace 'http://schemas.telerik.com/2008/xaml/presentation'.".

I'm hoping there is a solution to this problem so I can move on to the next challenge of finding any sort of documentation for this new control. I'm not looking for generic northwind examples with 10 lines of code-- I'm looking for documentation.

Thanks!

Metro theme not included?

I would like to know if the Metro theme is not included for my subscription. I have downloaded the WPF Q2 release and only see the default themes such as OfficeBlue,OfficeBlack and Windows 7.

How do I create a project and get the Metro theme to work?

Hide the cell selected focus rectangle

Is there an easy way in in the GridView to hide the cell focus rectangle.

I have a read only GridView that we do not show Lines on at all and the SelectionUnit is set to FullRow and other than the focus rectangle in the cell it looks exactly as we want it to.

I saw some talk on this in the Silverlight Forum back in 2009. It started with a loop through the rows rectangles but that no longer appears to work.
Silverlight Thread

More recently it was suggested that we have to create a custom style or data template to override the default and remove the focus rectangle from that. Is that the case for WPF also?

RadRichTextBox inside RadGridView

Hi there telerik team,

I'm using the RadRichTextBox with a RtfFormatProvider inside a RadGridView column like this:

<telerikGrid:GridViewDataColumn Header="Notes" Name="colNoteText" IsReadOnly="True" IsFilterable="False" IsGroupable="False" IsSortable="False">

<telerikGrid:GridViewDataColumn.CellTemplate>

<DataTemplate>

<Grid>

<telerikDocumentsRtf:RtfDataProvider Name="rtfDataProvider"

Rtf="{Binding Path=Note, Mode=TwoWay}"

RichTextBox="{Binding ElementName=TextBoxNote}" />

<telerik:RadRichTextBox Name="TextBoxNote" >

</telerik:RadRichTextBox>

</Grid>

</DataTemplate>

</telerikGrid:GridViewDataColumn.CellTemplate>

</telerikGrid:GridViewDataColumn>

The RTF text is displayed as expected. But when I'm sorting the grid based on other columns where the DataMemberBinding was set, the application is terminated with this exception:

Error: 0 : System.NullReferenceException: Object reference not set to an instance of an object
