set PreviewTileStateChanged event on databound tiles

Hello,

I have a RadTileView that is bound to a list of items, so that the tiles are automatically generated. I need to set the PreviewTileStateChanged and TileStateChanged events on the generated tiles. How can I do this?

I can't find any sort of 'tile created' event, and I can't set events in the ItemContainerStyle

ToolWindow minimizes with main window

Hi!

Our users want to be able to use floating panes as separate windows.

So I was just wondering if there is an easy way to prevent floating panes (ToolWindows) from being minimized when the main window is minimized?

Kind regards,

Fredrik

Disabling grouping while GroupPanel is visible

I dont want users do grouping in my RadGridView, but I want the GroupPanel visible (ShowGroupPanel = true), because I will use that horizontal bar as a grid-integrated toolbar, and place some custom functionality buttons there. (like export excel, refresh grid etc.)

How can I achieve that? Thanks.

The name "RadBusyIndicator" does not exist in the namespace "http://schemas.telerik.com/2008/xaml/presentation"

I searched in your forum without any solution. In your documentation I found no hint for my problem. By trying your Testproject I could reproduce my problem.

I am using the latest version of Visual Studio 2017 with Resharper. Also I am using the latest official version of your zipped Binaries. But I have no installation of your Control Suite and also no GAC-Registration. The assemlies are referenced from a Binaries-Folder.

Do you have any hint for me?

Best regards,
Ronny

My nominal scenario is :

1- Select Text tool

2- Select size of the shape (drag the mouse in the diagram)

3- Write text in the TextBlock in the shape

4- Open settings of the shape, and select Background and BorderBrush

5- Shape is saved (with Serialization and after in database)

The problem is when I'm going in settings (step 4) without wrote text (step 3). In this case, the shape is unusable (If I click on it, I can't update the text), and not saved (when I leave the diagram and go back, the shape isn't here).

I can't access to fired events and I don't know where come from this problem.

Can you help me ?

Thank you.

PaneGroup_PaneFrameStyle not available in Themes.Office2016

Hi,

I have been working on hosting winforms inside WPF, so I was running this sample project:
https://github.com/telerik/xaml-sdk/tree/master/Docking/WinFormsInsideDocking

But it only works when it uses Telerik.Windows.Themes.Office_Black, otherwise it gives error of Static Resource "PaneGroup_PaneFrameStyle" not found.

I'm using Telerik.Windows.Themes.Office2016 and need to implement the same style which is implemented in the sample project.

Kindly let me know, what needs to be changed for 2016 theme.

Thanks,

Tayyaba

RadCalculatorPicker TextBox functionality

I would like to use the RadCalculatorPicker in the following fashion:

In a dialog box or form, the user should be able to tab to the RadCalculatorPicker or click on its TextBox and the border should highlight as other controls do and the entire text should be selected.

From this point, the user should be able to freely edit the text in the TextBox, as long as it remains numeric, and the text should remain as he edits it and be reflected in the calculator when it is pulled down.

The user should be able to tab or mouse away from the TextBox, perform operations on other controls and subsequently return to the TextBox, whereupon the text in the TextBox should remain as it was when he left it. The Value should match this text.

While the user may/should be prevented from entering non-numeric characters, he should be able to leave the TextBox empty (""). It's not necessary that the control return a double? for the Value, as I can wrap the control with my own code to do so, but being able to have an empty TextBox is desired.

In short, I want the control to function as a normal TextBox (with numeric characters only) until the user clicks on the dropdown button, at which point the calculator appears and, starting with the string in the TextBox, functions as it does today.

I can derive a UserControl from this to perform some of what I want to do, but the TextBox and calculator seem to be very tightly bound and it appears that programming it to function as I desire would be a PITA, if possible at all.

Is there a way to make the control function in this manner? If not, would you consider making changes to it or creating a new control in the future that would work this way? The justification for it is to speed keyboard entry of numeric data while allowing the power of a calculator to be readily at hand.

Thanks
