HI, i've applied many updates of dll in last two years but never changed the
code of my application, the D&D was working fine in last deploy 2
years ago. Some update introduced the issue but i don't know which one.


I added a little demo with the issue. If u drag the button (new node)
from the ribbons inside the diagram the OnDiagramDrop event in the
diagram does not fire as expected. The handler is attached to the
diagram in the loaded event.


Can someone help me to understand what's is wrong?

Thanks.

Is there an up to date example of the current radtreeview node drag/drop functionality?

Examples and discussions I've found so far appear to refer to obsolete functionality, and while a simple xaml test works, events don't seem to trigger as expected.

In particular what are the relevant drop preview and event handlers and how do you get source and target nodes from the event arguments?

We have a requirement that different parts of the UI should be able to have a different color scheme. The Windows8 theme is nice because we only need to set a few colors, but Windows8Palette is a singleton that affects the entire application. Given that -- what's the best way to achieve this affect?

This thread (http://www.telerik.com/forums/using-multiple-windows8-themes) suggests that using implicit styles and loading them into the resource dictionary of the parts of the UI that we want to (http://www.telerik.com/help/wpf/styling-apperance-implicit-styles-overview.html) might work.

We would have to make a copy of Windows 8 theme, then, and instead of binding to Windows8Palette, we'd have to bind to something else. I suppose that's just a global text search&replace on the theme files, but it doesn't seem optimal to me.

Does anyone have any ideas/suggestions?
Thanks!

(It almost seems like the Windows 8 theme needs to support a dictionary of palettes, keyed by some string. And the Windows8Palette singleton can use some well-known value in the resource dictionary -- CurrentPalette for example -- to choose the actual colors to use)

Does your Barcode Reader support 2D?  If not, is that on your soon to be implemented list?

I derived a class from RadDiagram and attached device handlers to handle events. One event I want to handle is DiagramLayoutComplete, but the handler never seems to get called. Under what conditions should this event be raised?

In constructor:

Handler:

Any ideas?

Hi,

I have a property type if Image in the Model and i do not have path of the Image. It is designed at runtime through code.

I need to display in GridView Column, but Rad Grid View Image column needs URL of the image to display.

Please let me know how to bind the Image property to the grid column to display.

I have a RadGridView with AutoGenerateColumns="true". Now i need to change one of the columns from being a plain column to a comboboxcolumn in code behind. What is the best way to do this? 

So instead of displaying a grid with say 3 columns:

[id] [PersonId] [PersonName]

i want 2 columns and catch the column with PersonName an replace it with a comboboxcolumn so i can pick any row in the column. The comboboxvolumn sould display the [PersonName] but the value should be the [PersonId].

Also the grid is used to display various tables so i cant use a predefined template i think?

I dont know if this makes sense? :)

Hello,

I'm not able to get implicit themes (No Xaml) working when using a class inherited from RadCartesianChart.

The typical way to get this to work would be to add this to the Application's resource dictionary:

<Style TargetType="controls:RadCartesianChartEx" BasedOn="{StaticResource RadCartesianChartStyle}"/>

however, this does not work as there is no RadCartesianChartStyle resource defined in the theme assemblies.  Any ideas how to get this to work?  My inherited charts are not displaying when using the NoXaml libraries.

Thanks!

Hello, I have a RadGridView with several columns. Only one column is editable, the rest are readOnly. When a user opens a cell in the editable column and press 'tab' an error that says IndexOutOfRangeException was unhandled' specifically: 'An unhandled eception of type 'System.IndexOutOfRangeException' occurred in Telerik.Windows.Controls.dll'. Can anyone help me understand this error and how to get rid of it to allow the user use tab to move to the next cell. Thank you.

Hi Team,

1) As I am providing my own customEditors based on my property types, I am unable to set the focus to the Custom Editors when I am tabbing through the PropertyGrid. I am providing my own style ( Grid layout) to the property Grid.Coud you please help me in this regards.

2) Secondly, I want to provide my style similiar to the style which telerik provides when we make AutogeneratePropertyDefintions as true.
Currently I am doing Autogenerate as False and providing my own style ( grid layout) as a result what happens is:
          a) The PropertyNames are getting overlapped by the Thumb(gripper that exists between the property name and the custom editor). I always have to hold the                gripper and move it right to see the complete name. Is there a way , so that I could align my property grid like: <PropertyName><gripper><Editor>. the                      Property Name takes the size as per its text and the rest space is completely taken by the Custom Editor.( Mostly Like Stack Layout)

Regards,
Imran
