RadialGauge Curved Tick Label Text

Hi,

We are working with some large numbers on the Radial Gauge. Some of these numbers are overlapping on our custom gauge unless the font size is set unacceptably low with few labels on the gauge. Also, large numbers (in the 10s of billions range) look rather square in contrast to the curved radial scale.

Is there any way to have tick label text curve around with the radial scale? Do you have any suggestions on the best approach?

Cheers,
Wayne Reid

Toolbox icon still point to old Telerik dlls

Hello,

I recently installed TELERIK 2009Q2 for WPF and every thing went fine.

When I create a new project and add a gridview control using View -> Toolbox,
the control and all the other DLLs point to the library where the older Telerik version was installed (and still exist on my computer).

I did an automatic MSI install and not a manual one.

Your help will be most appreciated.

WPF Examples Demo Project

I have downloaded the trial and demo for the WPF. Could someone tell me how the left navigation bar is built? This is the panel with all the images for each control in the toolkit that you can select.

I open it in VS and HomePage.xaml does not seem to contain it. Examples.xml seems to contain declarations for the items in the list.

I am new to WPF and Telerik so thanks for bearing with me.

Binding to Collection

When I expand the column, to view the child table, I get the error: A TwoWay or OneWayToSource binding cannot work on the read-only property 'AddressFamily' of type 'System.Net.IPEndPoint'.

I had the same error on the parent table - but got around it by explicitly defining the columns and the column bindings as one-way. Not really sure why that was required either, but it worked. But, can't figure out how to do that for the child table. And, I'm not sure if this was the correct approach anyway.

I get this scenario to work correctly with DataSets - but don't want to have to create DataSets for the 50+ objects I need to do this for.

Any thoughts?

The datasource is a collection of custom objects.

XAML is...

The grid cell selection and current row selection can become out of sync

WPF version = .Net 3.5 SP1

OS = XP SP3

exact version of the Telerik product = 2009 Q2 SP1 (2009.2.813.35)

Step by step instructions on how to reproduce erroneous behavior.
1. select cell in RadGridView and the row selector moves to that row and the row is highlighted.
2. edit cell
3. select a cell in a different row and the row selector doesn't move and neither row, previous nor current, are highlighted.
4. select a cell in a different row and the row selector moves to that row and the row is highlighted.

It appears that if a cell is edited it prevents the current row to be set to the row of the next current cell.
For example:
1. Edit cell.
2. Select a cell in a different row.
3. Hit Up arrow on keyboard.
4. The selected row becomes the row above the row selected in step 1.

DragDropEventArgs.DragDropOptions -> CurrentDragPoint but no GetPosition method

Hi to all,
i'm using RadDragAndDropManager to make possible to drag a TreeViewItem to a MindFusion Wpf Diagram...to make the game more complex we use the AvalonDock component to handle dock interface.
Actually all the staff work quite well but i have a problem about the DragDropEventArgs and the mouse position. i don't find a way to get the correct mouse coordinate when i drop the treeviewitem into the diagram. On many other event args as for example MouseButtonEventArgs i could get the correct position using the method: e.GetPosition(diagramInstance)...but i don't find a way to do it with the DragDropEventArgs.

Any advice?

Really thanks.
Diego

Item Source Update Notifications

Dear sirs,
I would like to ask, if possible, if you could explain in a very simple way how can I get my GridView to auto update when the SQL table it is associated to changes. I already read some of your examples on the DataViews, but I didn't get it.
Please have in mind I'm a novice programmer, so samples are welcome!
Best regards,
Bernardo Caldas
