Questions on UI for WinForms Forum

Hello.

I need to add a set of comboboxes as a new row to a RadGrid dynamically. I've been able to get close by creating a ComboBoxCellElement off of GridDataCellElement and setting it inside the CreateCell event. However, because of UI Virtualization, the comboboxes get re-used on different rows as I scroll around, and IsCompatible only seems to work when a custom column type is being used, which I am not using here.

Is it possible to apply specific controls to individual cells? Or can UI Virtualization be turned off for RadGridView?

Thanks,
Mike

[Solved] RadMultiColumnComboBox Localization Provider?

Hi,

As we can localize RadGridView by using

Telerik.WinControls.UI.Localization.RadGridLocalizationProvider

and assigning it to

RadGridLocalizationProvider.CurrentProvider

to change the text of certain elements on RadGridView by implementing our custom class
as follows:

Private Class MyEnglishRadGridLocalizationProvider

Inherits Telerik.WinControls.UI.Localization.RadGridLocalizationProvider

Public Overrides Function GetLocalizedString(ByVal id As String) As String

Select Case id

Case RadGridStringId.NoDataText

Return "Between"

Case RadGridStringId.AddNewRowString

Return "Hey, you're new row here.."

Case Else

Return MyBase.GetLocalizedString(id)

End Select

Return "Bad, Bad Grid"

End Function

End Class

Public Class Form1

Public Sub New()

' This call is required by the Windows Form Designer.

InitializeComponent()

RadGridLocalizationProvider.CurrentProvider = New MyEnglishRadGridLocalizationProvider()

End Sub

End Class

Likewise, how can we localize gridview component embedded in RadMultiColumnComboBox?

Thanks

Prevent item selection from changing when a new item added

When using a bindinglist on a ListView datasource, everytime a new object is added to the List, the view will automatically select the new item.

Shortcut in inactive window

When we assign shortcuts to a RadMenuItem in a context menu on a form, the shortcut is also triggered when the form is not active.

The shortcut is working properly when the form is active, but when the form shows a modal dialog on top, the shortcut from the underlaying window is still active and can be triggered.

How can we change this behaviour?

multi selection on parent nodes

Hi,
I have several parent nodes, and what I would like to do is be able to multi select the parent nodes and the child nodes in such a way that only one node under a parent or the parent can be selected.

For instance, suppose I have this example:
Parent1
- Child1
- Child2
Parent2
- Child1
- Child2
- Child3
Parent3
- Child1

I would like to be able to start off with all the Parent nodes selected, and then be able to do any combination thereafter by only having one node from each parent selected at any time.

I have tried Canceling the selection event in the SelectedNodeChanging handler (by removing the event handler, then programatically setting the selected nodes, and finally adding the handler back) however the tree view does not refresh.

Is there perhaps a built in way of achieving this or am I going about it all wrong?

Thanks,

Treeview

C++ Examples?

I have seen this asked but have not seen a link to some examples using Telerik in C++.
Any pointers? Selecting new Telerik project only offers VB and C#. . Presently running VS 2010 Pro, with SP1 on a Windows 7 64 Bit OS. Running latest download of Telerik (Q2 2012). Radcontrols for Winforms shows up and works in C#, but would like to move some C++ programs and spiff up the GUI.
Thanks,

Lou
