Disabled Children Nodes Checked on Root Selection

Using the following code: (Telerik UI for WinForms 2015.2.728)

tvElements.CheckBoxes = true;

tvElements.TriStateMode = true;

RadTreeNode root = tvElements.Nodes.Add("Classes");

foreach (CNFClass cls in CNFConf.Classes) {

RadTreeNode parent = root.Nodes.Add(cls.UID.ToString(), cls.Code, null);

parent.ToolTipText = cls.Desc;

parent.Enabled = cls.Enabled;

}

Checking the root node will check all Enabled and all Disabled children nodes.

Seems like this may be a bug, is there a workaround?

RowsChanging - Event does not fire

Hello,

I'm experiencing some problems with a gridview bound to a bindingsource (using entity framework 5).

The RowsChanging event does not fire on binding operations, neither on the initial binding nor on any subsequent reloading of data. The RowsChanged event does. To my understanding before every RowsChanged event, the RowsChanging event should fire at least once.

I tried using the gridview.Rows.CollectionChanging event, but it does not exist - though it should according to the documentation.

The event DOES fire if I modify the rows at runtime (like removing one row).

simplified version of the code (tried variations of binding to the MasterTemplate, with or without BeginEdit etc):

Kind regards,

Andreas

public RadForm1()

{

InitializeComponent();

radGridView1.RowsChanging += RadGridView1OnRowsChanging;

bs = new BindingSource {DataSource = context.Sonderthema_Art.ToList()};

radGridView1.DataSource = bs;

}

private void RadGridView1OnRowsChanging(object sender, GridViewCollectionChangingEventArgs gridViewCollectionChangingEventArgs)

{

throw new NotImplementedException();

}

Adding controls to the Group header

Is it possible to add controls to the group header row? For instance, if I wanted to group my rows by a certain field, and add a combo box to each group's header row whose value affects all the rows in the group, is that possible? Thanks!

Changing dock state programatically

Regarding dock panel:

Is it possible to toggle between docked and autohide programmatically? Also how do I change the width and height of a panel that is floating or hiding?

One of the major problem I have with auto hide is I cannot adjust the height when it is hiding. So when user hover on the docking bar, he can only see a portion of it instead of the whole panel.

Regarding dockpane on a tabbed document:

I checked the "CloseButtonVisible" to false, but that button is still present and nothing to stop the user clicking on it.

Sometimes when the user click or hold on two tabs too quickly, it will swap the tab position instead of focusing on the new tab. Is there anyway to prevent this to happen?

Print RTF from Windows Service

Hello

I am using the RichTextEditor control to allow users to create a document (which may include embedded images). The RTF text is then stored in a database, and a Windows Service is supposed to print the document at a later date.The Windows Service does not allow any dialog or form to be shown, so neither a normal print dialog, nor converting to PDF and printing with a PDF Viewer can be used to print.

My current approach has been to convert the RTF to a PDF with RtfFormatProvider and PdfFormatProvider, save it to a file, and print it using the Print verb. However, no matter what options are given to the Print process, it still tries to start the Adobe PDF Viewer to print.

Does Telerik offer a way to print RTF documents without any UI? Or perhaps stock WinForms has a way that I am overlooking.

I am using version Q3 2014 (2014.3.1104)

Thank you for any assistance.

Apply custom sorting in a grouping column binding to a string property programatically

Hi, I am trying to apply custom sorting to a grouping column designed programatically that is binding to the grid as string.

The problem is that I cannot get event fired because for example I do not allow user to sort the columns, It is made programatically and it is fixed by design.

How can I apply a custom sorting method to a grid designed programatically for a grouping column and that it is fixed ??

example:

Column Column
====== ======
4 1
2;33 2
1;35 4
11 5
2 11
1 13
13 1;35
5 2;33

I have been trying to apply this example but I can not get it works, for example events do not fire.
http://www.telerik.com/help/winforms/gridview-sorting-custom-sorting.html

Any help would be appreciated.
