RadDropDownListElement - Tooltip

Hi,

I am trying to add a tooltip to a RadDropDownListElement embedded in a Ribbonbar.

One may add tooltip text directly, to the ListElement or to the Textbox, but no one results in a tooltip being displayed.

I do not wish to add tooltip to individual items in the dropdownlist, but just one tooltip to the entire control.

Any advice?

GridViewCheckedDropDownListColumn

I am trying to create a GridViewCheckedDropDownListColumn. I have some of it working.

It is creating the column and the drop-down is displaying as it should. However, the main cell does not show the checked items after the drop-down is no longer displayed. Nor does it remember which items had previously been checked when the drop-down is displayed a second time.

I wasn't able to attach my project, so here is the important code:

public class Foo

{

public int Id { get; set; }

public string Value { get; set; }

public bool IsSelected { get; set; }

}

public class Boo : Foo

{

public List<Foo> Foos { get; set; }

public Boo()

{

this.Foos = new List<Foo>();

}

public class RadCheckedDropDownListEditorElement : RadCheckedDropDownListElement

{

...

}

public class RadCheckedDropDownListEditor : BaseGridEditor

{

public string ValueMember { get; set; }

public string DisplayMember { get; set; }

public string CheckedMember { get; set; }

public override object Value

{

get

{

var listEditorElement = (RadCheckedDropDownListElement) this.EditorElement;

return listEditorElement.DataSource;

}

set

{

var listEditorElement = (RadCheckedDropDownListElement) this.EditorElement;

listEditorElement.ValueMember = this.ValueMember;

listEditorElement.DisplayMember = this.DisplayMember;

listEditorElement.CheckedMember = this.CheckedMember;

listEditorElement.DataSource = value;

}

var listEditorElement = (RadCheckedDropDownListElement)this.EditorElement;

listEditorElement.DataSource = value;

Text wrapping in a tree view node and multi line support

Hi,

I am using a RadTreeView to display a set of nodes where the text is very long. Is it possible to specify a max width for the treeview node and have the text wrap within the available space extending down (or clipping beyond the horizontal size).

(I have read some other posts on this but there is nothing in there for this year)

Regards
James

[Solved] Are there some bugs in localization and cursoring?

Hello I am examining PDFViwer PdfViewerNavigator controls. But in both of two, something is gone wrong.

Firstly, in RadPdfViewer cursor property only allows "WaitCursor". When I try to change as "Default", it is not allowed.

Secondly, in RadPdfViewerNavigator localization is not allowed. I override like this:

01.public class PdfViewerLocalization : PdfViewerLocalizationProvider

02.{

03. public override string GetLocalizedString(string id)

04. {

05. switch (id)

06. {

07. case PdfViewerStringId.NavigatorOpenButton: return "Aç";

08. case PdfViewerStringId.NavigatorPrintButton: return "Yazdır";

09. case PdfViewerStringId.NavigatorPreviousPageButton: return "Önceki";

10. case PdfViewerStringId.NavigatorNextPageButton: return "Sonraki";

11. case PdfViewerStringId.NavigatorCurrentPageTextBox: return "Şimdiki";

12. }

13. return base.GetLocalizedString(id);

14. }

15. }

But when I execute, It is same. English is not changing.

Could you help me for this situations?

Kind regards.

Open floating Window

Hi,

Is it possible to add a floating window to RadDock without docking the form as first step. I am using the following code:

Dim h As HostWindow = RadDock.DockControl(New MyForm(), DockPosition.Fill, DockType.Document)

h.DefaultFloatingSize = New Size(800, 600)
h.DockState = DockState.Floating

h.Select()

The problem is, that this causes a lot of flickering and rearranging of the existing docked windows.

When added with Dockposition.Fill the new window will get focus. When floated the window in focus when the operation started may be hidden behind another window. Selecting the original window causes flickering between windows.
