How to enter into 'rename item mode' through code?

Hi telerik,

We allow the users to rename items through pressing F2 in treeview - works like a charm.
However, users have requested that Rename should be available throgh the context menu.

Can we through code make the treeview enter into the mode where the name of an item is edited?

Thanks,

Anders, Denmark

Radgridview contextmenu not working in the latest version

Hello Team,
We are upgrading the telerik controls to q2 2011 version. In the previous version the Radgridview right click contextmenu was working fine, but not now. What do I have to change in the below code to get the popup menu when I right click the selected row?
Let me know.

Thanks

<telerik:RadGridView.ContextMenu>

<ContextMenu IsVisibleChanged="ContextMenu_IsVisibleChanged">

<MenuItem Header="Export To Excel" Command="Commands:GlobalCommands.ExportGridToExcel"

CommandParameter="{Binding Path=PlacementTarget, RelativeSource={RelativeSource AncestorType={x:Type ContextMenu}}}"/>

<MenuItem Header="Export To Word" Command="Commands:GlobalCommands.ExportGridToWord"

CommandParameter="{Binding Path=PlacementTarget, RelativeSource={RelativeSource AncestorType={x:Type ContextMenu}}}"/>

</ContextMenu>

</telerik:RadGridView.ContextMenu>

Can a Telerik or native component do this?

I have a grid with three columns, and two rows. Here's the basic layout:
___________
| A | B | C |
------------------
| D | E | F |
------------------

Grid cells A and C are used for something not relevant here. The bottom row is smaller than the top row.

I want a ScrollViewer (or anything that can contain items and scroll horizontally) in Cells [D,E,F] (ColumnSpan of 3). The ScrollViewer would hold RadCharts. When a chart is clicked, I want it to animate and move up to cell B which will provide a much larger view of it. When another chart is clicked in the ScrollViewer, this chart should animate upwards while the previous chart simultaneously animates back to the ScrollViewer along the bottom.

So if the bottom area holds 30 charts, you could always have one selected and viewed in cell B.

I was looking at RadCarousel but I don't know if it can be customized enough for that. Any ideas?

Cannot find type Telerik.WinControls.Design.NewItemGlyph in module Telerik.WinControls.dll.

I have a RadPaneGroup with Panes that have a header description. Due to the length of the header descriptions and the number of Panes (4) the paneGroup takes up quite qa lot of witdth. If I set the Width of the panegroep with for example Width=700 I get a designer error as displayed below. If I do a binary scan I find the NewItemGlyph in Telerik.Windows.Controls and Telerik.Windows.Controls.UI, so I included those references. Unfortunately this does not solve the error. The application still runs.

Any clues how to solve this?

How to refresh datagrid rows using data virtualization

Hi,

I am using data virtuialization with the help of VirtualQueryableCollectionView. Everything works allright. Now I change the content of some database items on a button click. How can I refresh the rows of my gridview. The grid only shows the right content of rows that are newly loaded. Some rows (I guess these are rows that are already displayed and still kept in memory) are not actual.
What do I have to do?

Here is a source code example:

public partial class MainWindow : Window

{

WomanEntities _container = new WomanEntities();

public MainWindow()

{

InitializeComponent();

VirtualQueryableCollectionView view = new VirtualQueryableCollectionView(_container.Women.OrderBy(k => k.ID));

view.LoadSize = 20;

DataContext = view;

}

private void button1_Click(object sender, RoutedEventArgs e)

{

WomanEntities _container = new WomanEntities();

IQueryable<Woman> women = (from k in _container.Women

where k.Age == 60

select k);

foreach (var item in women)

item.HairColor = "white";

_container.SaveChanges();

((VirtualQueryableCollectionView)DataContext).Refresh();

}

Thanks for help in advance

Multiple Calenders Support

We are looking at the ScheduleView control as part of a requested SharePoint 2010 solution. The OOB Calendar in SharePoint can do overlays of multiple calenders, but only up to 10. Can the ScheduleView control do this, and can it do more than 10?
Thanks!

Close filter-dialog

We are using the filter-dialog in our gridviews. This works fine and fast.
What we are missing here is a Button / ShortCut to close the dialog.
When we now want to close the dialog we have to click (mouse) outside the dialog.
Is there a hidden feature maybe?
