I want to generate the image of BarCode without showing on the WinForm.  How to assign "Code39Extended" to Symbology?

 RadBarcode rBL = new RadBarcode();
 rBL.Symbology = "Code39Extended";

Thanks.

Hello,

I'm struggling to get some events to work on a RadListViewElement, which is a child of a custom RadElement, which in turn is inside another custom RadControl. I guess a few lines of code will help to describe this:

Imports Telerik.WinControls
Imports Telerik.WinControls.UI

Public Class xElement
    Inherits RadElement

    Private listElement As RadListViewElement

    Public Sub New()
        'Me.NotifyParentOnMouseInput = True
        'Me.ShouldHandleMouseInput = True
        'Me.Capture = True
        'Me.CaptureOnMouseDown = True
    End Sub

    Protected Overrides Sub OnLoaded()
        MyBase.OnLoaded()

        AddHandler listElement.ItemMouseUp, Sub(s, e)
                                                If e.OriginalEventArgs.Button = MouseButtons.Left Then
                                                    listElement.SelectedItem = e.Item
                                                End If
                                            End Sub
    End Sub

    Protected Overrides Sub CreateChildElements()
        MyBase.CreateChildElements()

        listElement = New RadListViewElement
        With listElement
            '.ShouldHandleMouseInput = True
            '.NotifyParentOnMouseInput = True
            '.Capture = True
            '.CaptureOnMouseDown = True
            .ViewType = ListViewType.ListView 
            .DataSource = New List(Of String)(New String() {"a", "b", "c"})
        End With
        Me.Children.Add(listElement)
    End Sub

End Class

Imports Telerik.WinControls

<ToolboxItem(True)>
Public Class xControl
    Inherits RadControl

    Private element As xElement

    Public Sub New()
        element = New xElement()
        RootElement.Children.Add(element)
    End Sub

End Class

How can I find out the selected layout  (list, small icon, etc.) chosen by the user at the point the dialog is closed?

Thanks

Hello

I would need to calculate the height of a grid as it would be if all the rows were visible.

I need this value to change the location of another element just below the grid.
More precisely, the grid and the other component are located within a tablelayoutpanel that has two rows, the top one is of variable height and the second of fixed height.

When the form is resized (or the grid re-loaded), I can have two situations:

1. the grid does not fit in the available space of the first row, in this case I do not need to adjust the position of the second row of the table layoutpanel

2, the grid does not fill the available space of the first row. In this case I need to change the height of the second row in order to have the second element "just" below the grid without having a large white space between the grid and the second element.

I have tried to calculate the grid height as the sum of individual gridrow height but since the gridheight of a non visible row = -1 this does not work.

Therefore I would like to have the height of the grid as if all the rows were visible and the I can proceed with my redimensionning of the layoutpanel.

I am not sure my explanations are clear ..

Thanks in advance for any suggestion

Best regards

I would like to remove the Group option from the DataFilterAddNodeElement dropdown list when I'm adding to an existing group. Basically I only want to allow adding expressions to groups and prevent nested groups from being created. However, I still want to allow adding groups to the root node, just not to other groups. Is there a way to hide or disable the Group option in this scenario?

Thanks

Hi Team,

   When click or double click in the field and the full number doesn't get highlighted on the RadMaskedEditbox.

Hi,

How can I prevent the DragDrop operation in the File Open and File Save dialogs?

Thanks

Hello!

I've got an Unbound RadGridView control that loads without issue.

Each row includes a Hierarchical grid.

I control the main grid column header height with this: gridTest.TableElement.TableHeaderHeight = 15

but I have not been able to figure out how to adjust the Hierarchical grid's column header height.

Any help you can offer would be appreciated :)

-C

RadDateTimePickerArrowButtonElement button = (RadDateTimePickerArrowButtonElement)this.DateTimePickerElement.ArrowButton.Children[1].Children[1];

((ImagePrimitive)button.Children[4]).Image = ImageLibrary.Calendar;

which failed because the first Children[1] did not have any children resulting in a null reference.

I also tried this which looked obvious ...

this.DateTimePickerElement.ArrowButton.Image = ImageLibrary

.Calendar;
but the appearance of the control did not change.

#5
When my custom control sets

this.Format = DateTimePickerFormat.Custom;

this.CustomFormat = "MM/dd/yyyy - ddd";

these properties are ignored and must be explicitly set for each control where implemented.  Other values like

this.NullText are inherited from my controls as expected.
