there is a bug in drag/drop within the treeView.
here's the scenario:

-A
--B
---C

each letter is a RadTreeViewItem. A is root, B is a child of A, C is a child of B.

Now, A.IsDropAllowed=true, B.IsDropAllowed=False,

I want to move C before B, thus making it a child of A. BUT when the line indicator shows that the item will be dropped "Before B" the tooltip shows up as (X), and does not allow the drop.

Setting a dropTarget to isDropAllowed=False should mean you cannot drop it under that item. If i want to add something before or after it, it should use the isDropAllowed of that item's parent.

We're able to edit an existing record, but couldn't successfully include a record into the GridView. Our data is stored in a List<T> which is used to commit each record to the backend.

 

Pressing the INSERT key on the GridView will call the 'AddingNewDataItem' method.  When the cursor leaves the edited row, the 'EditEnded' method is called.  When this method executes to the end, an error occurs:

 

ERROR: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

Record editing is working, but crashes when committing a new record.  Secondly, is it possible to call the 'AddingNewDataItem' method rather than wait for the user to press the INSERT key?

 

-Trav.

Should be a simple question....  How do I change the background color of a chart?

These don't seem to do it for me:

this

 

.RadChart1.Background = new SolidColorBrush(Colors.Blue);

 

this

 

.RadChart1.DefaultView.ChartArea.Background = new SolidColorBrush(Colors.Black);

The only way I have done it so far is to override the whole control template, and set the Background on the WrapPanel....which is very much over-kill.  I must be missing something obvious.  If you want to change the background color of a control, you usually just set the Background property...

Hello

I know this is going to sound stupid, but I was wondering if anyone could explain in a simple walkthrough on how to use the RadPanel Bar in Microsoft Expression Blend 2.

I'm a super noob as you can tell.  thank you in advance

Dear All

I've just spent a while trying to get a hand-authored theme (basically identical to SimpleTheme, but in my assembly) to work with the grid, but without success.

I can reference the SimpleTheme class in Telerik.Windows.Controls.UI.Simple and my grid reflects this theme, but if I copy the theme into my project (after fixing up namespaces etc.) and setting the Theming.Theme attached property on the grid to point to my derived class of Theme, I end up with a completely blank grid.

I have two ideas as to why this is happening:
- Assemblies containing themes authored by Telerik are signed with a strong name key
- The syntax I am using to set up the ThemeResourceKey that points a particular style at a particular part of the grid is incorrect.  The following example is from Telerik code:

x:Key="{telerik:ThemeResourceKey ThemeType=telerik:SummerTheme, ElementType=grid:GridViewItemsControl}"

and I'm a bit surprised that ThemeType is assigned like this using just a string.  I've done the same, using the namespace of the class I have which is derived from Theme, but without success.

Can you provide us with a step-by-step guide to hand authoring themes for the Grid, or is this currently not possible?

In the meantime, we are going to continue styling the grid without unifying this into a Theme.

Regards

Chris

Hi,

I've addressed this issue before in this thread - Telerik's WPF controls don't initially support SQL Server Developer Edition (or other versions that don't support the user instance flag in connection strings).  I had forgotten about this issue when I downloaded the Q2 release, and was a little confused when I could get the demo to start without immediately crashing!  I know you don't have plans for native support of different SQL Server versions (which I still think would be nice), but I did see Hristo say in the other thread that "We will be shipping a .config file with the official version and the installer should handle the DB configuration for you."  I did see the .config file and just edited the settings through the property pages in Visual Studio.  However, the installer definitely messed up in configuring my database server.  Is there any chance that in future releases the installer will do this automatically?  It may seem like a small feature, but it would make your product seem a whole lot more professional if I didn't have to tweak the demo's configuration in order for it to run, and I'm sure everyone not using SQL Express would very much appreciate it :)  Let me know how feasible this might be for Q3!

Thanks so much,

UIdev

Hi,

I've implemented a chart with multiple areas (i get the percentages of the cpu's and add it to the chart data) but i have some problems:

1. How can i add a fixed Y-axis (0-100 major tick 10 minor 5) because now it's dynamic (changes if value is greater or smaller then axis)
2. How can i make the X-axis start at 0 because now i've got a gap between the first value and the Y-axis (because Y is always 1 as start)
3. How can i remove the label on the points displaying the value

Code for populating the chart:

XAml

Any ideas?

Our designer would like us to have a grey row separator across the width of the grid.  At the moment, we can only do this as far right as the right edge of the last defined column.

Is there a way to achieve this?

(We are having a related issue with the mouse-over highlighting for a row.  We would like that to go to right edge of the grid as well.)

Regards
