Visual difference between GroupRenderMode "Flat" and "Nested"?

Is there a visual difference between the two GroupRenderModes?

When I alternate between these settings, I don't see any visual difference in how Grouping is presented so I'm wondering if it is even working in my grid.

Maybe it's only an internal difference in performance?

Some images in the documentation would be really helpful there.

Extended grouping

Hi!

I need some support to create a treeview, that is bound to a dataset and hierarchically displays the content in the following way:

Customer 1

Orders (<- Group node)

Order 1

Shipping Notes (<- Group node)

Shipping Note 1

Shipping Note 2

Invoices (<- Group node)

Invoice 1

Order 2

Order 3

In the underlying relational structure are the four datatables "customer", "orders", "shipping notes" and "invoices" with parent-child relationships between "customer" - "orders", "orders" - "shipping notes" and "orders" - "invoices". The dataset structure corresponds to the database structure, so I'm not able to change it.

I tried to extend the basic grouping example from Valentin Stoychev using a CollectionViewSource, but i was not able to combine them.

Can you give me a hint how get it to work?

Thanks!

AutoComplete is not working

Hi Experts,

I have tried your AutoCompleteBox with the following code, but it is not working. I could not get any suggesstions and the dropdown list is not showing any suggesstion list. Simply the control works like a TextBox only. Please help me, what is my wrong.

<Window x:Class="Interactivity_Behavior_Demo.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:Telerik="http://schemas.telerik.com/2008/xaml/presentation"

xmlns:local="clr-namespace:Interactivity_Behavior_Demo.Behavior"

Title="Test Demo"

Width="525"

Height="350">

<Telerik:RadAutoCompleteBox Name="autocomp" Loaded="autocomp_Loaded_1" Height="30" Width="120"/>

</Window>

public MainWindow()

{

InitializeComponent();

_Source = new ObservableCollection<string>() { "hello", "abc", "123" };

autocomp.ItemsSource = Source;

}

private void autocomp_Loaded_1(object sender, RoutedEventArgs e)

{

autocomp.IsDropDownOpen = true;

autocomp.AutoCompleteMode = Telerik.Windows.Controls.Primitives.AutoCompleteMode.Suggest;

autocomp.TextSearchMode = Telerik.Windows.Controls.TextSearchMode.StartsWith;

}

0311 DEV hotfix error

Just installed RadControls_for_WPF_2013_1_0311_DEV_hotfix.

Now, drag-and-dropped chart shapes show a really weird behavior. When moving them (after the drop action) they are instead copied. After four copies, the move operation is successful. Only the original shape (not the three "copies") show this behavior.

Even though this is a nightly build, I'd say this kind of bug is a bit embarrassing :)

Need to view DetailsPresenter without affecting my row selection.

Hi,
I am using a RadGridView and using a DetailsPresenter to present the row details externally. I also have a GridViewSelectColumn to display the checkbox for each row selected which also provide me a Header checkbox out of the box for select/unselect all.

Now here is my problem. I need to select a row to view the details in the detailPresenter but on doing this the selection checkbox state is toggled. What I want is to be able to move through my rows to view the details without actually doing a selection. I tried using the GridViewCheckboxColumn which works well, however its missing the header checkbox.

Here is what I want to achieve:
1) Have a column with checkbox that the user can check/uncheck to select a row .. the column should also have a checkbox header which will help with select/unselect all rows.
2) Navigate through the rows to view details in the details presenter without affecting my selection checkbox state.

Can you please suggest the best way to achieve this functionality?

Thanks.

Need different ContextMenus on RadGridView rows and columns

I need different ContextMenus on the Rows and Columns. The context menu on the Rows should let me perform custom Cut/Copy/Paste functionality and the ContextMenu on the columns should let me perform custom formatting on individual columns. My problem is I can only seem to create a single ContextMenu for the grid as a whole.

Can I have one for the rows and one for the columns? If so, what is the syntax?

Thank you,

James

Messed Up 2-Line Chart

Any idea why my chart looks like the attachment?
My guess was that my list of x-axis values was out of numeric order but as far as I can tell it's not.
Notice that it only seems to be my second line that is wacky. I try to generate the x-axis values by combining the possible values from my first line with my second in case I don't have a full set of one or the other.
