I noticed that there was a Header Row option available (ToggleTableLookFirstRowOptionCommand) but it does not seem to have any effect. Is there something I am doing wrong?

Suppressing the "Drawing" of a series every time the databound series changes

Hi,

I have a RadChart containing a SeriesMapping whose ItemSource is data bound to a collection. This collection is also bound to a grid so the contents can be altered. This works great, however whenever I add a new item to the collection the series on the chart appears to redraw, ie it draws from left to right.

I fully understand that the collection has changed so this needs to be reflected in the chart, but the drawing it does is problematic, is there any way to control how this renders? Ideally I don't want to see it being drawn in real time, only once it has been fully rendered. I know this might mean a slight delay but would be much more desirable from a user perspective.

Thanks

Application menu alignment

Hello, I'm using a custom RibbonView style derived from the Windows 8 theme.
When I press the application menu button (HorizontalOffset="0" for DropDownPopup), the popup menu appears as in the attached image "1" or "2" depending on different computers.
To correct this, when I set HorizontalOffset to the width of the popup menu, I obviously get the results as in the image "2" or "3".
I have tested several properties to control the popup behavior, but nothing helped and I have no idea why this popup behavior appears different for some specific desktop settings.
Can this be fixed? Thank you!

Problem with Office2013 theme and backstage

Hello,
I'm trying to use the Office2013 theme within my application.
One problem I have is I have, for one of the backstage item, a content that contains TextBlocks. The default background color for the backstage content is white and the text color for TextBlocks is also white, so the text is not visible.

Hi.
I found that great example: http://www.telerik.com/help/wpf/raddraganddrop-between-treeview-gridview.html
But my question is that, is it possible to drag from radgridview to radlistview?
I'd like to drag Product(from gridview) to Category(from listview) with auto-insert to database.

Thanks!

Multi-Select ComboBox Column

I have tables: Output <---> ZoneOutputs <---> Zone

The grid display Outputs. I'd like to add a column that allows me to select multiple zones from a combobox (or popup editor). Is there a built in way to do it, and if not is there a semi easy way. Just the display part... I think I can do the behind the scenes part of taking the checked items and turning them into ZoneOutputs (I'll probably handle it in the ViewModel as the properties change).

Image Example

Thanks,
Brian

Setting text in RadBusyIndicator

Hi everyone,

I am developing a WPF application in which I use RadControls.
I have declared an indeterminated RadBusyIndicator control in a Window's markup.
I have to implement 2 methods in the Window's code-behind to respectively show and hide the BusyIndicator.

The show method takes an input parameter corresponding to the message to display in the BusyIndicator.
I have looked at this help page : radbusyindicator-features-custom-busy-content.html
I have read I can define a custom BusyIndicator content by declaring a DataTemplate.

I have though about declaring a DataTemplate containing a TextBlock.
But I do not know how to set the TextBlock's text from the show method.
Can you please describe me a way to do it ?

I have thought about creating a property in the Window's code-behind representing the TextBlock's text.
I could set the Window's property from the show method.
I have also thought about binding the Window's property to the TextBlock's Text property but I do not know how to do it.

Thank you in advance for your future help.

How does the RadComboBox handle nulls?

I've discovered something about the out-of-the-box WPF ComboBox. It apparently doesn't handle nulls coming from the database very well. If there's a null in the database, and you do something like this:

<ComboBox x:Name="cmbMajorProbByInterviewer"

VerticalAlignment="Top"

ItemsSource="{Binding Source={StaticResource aSICodesSubstanceTypeViewSource2}}"

DisplayMemberPath="SubstanceDesc"

SelectedValue="{Binding MajorProblemByInterviewer}"

SelectedValuePath="SubstanceType"

Grid.Column="3" />

then it's my experience that if there's a null for the MajorProblemByInterviewer, what the combo box will show is the first item in the items source coming from aSICodesSubstanceTypeViewSource2. That is not what I want.

So I'm wondering, does Telerik's RadComboBox show nothing (i.e.: SelectedIndex == -1) if the value coming from the database is null?
