I have 12 radio buttons that I want to place in the same group on a RadRibbonBar.

I would like to have them line up almost grid like - with three rows, and four columns.

They do, however, need to remain in the same group.

Is there a way to do this, without having to deselect all items in the code behind after each and every different RadRadioButton is clicked?

There are way too many Radio Buttons to keep them all lined up vertically or horizontally.

Thank you! :)

[Solved] inherit radform

I've created RadForm1 and renamed it to MotherForm and put several components on it. Then I've created new RadForm(AlterForm) and inherit it from MotherForm.

public partial class AlterForm : MotherForm

But in AlterForm designer I've got an error

The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: DropForm --- The base class 'AdminControl.MotherForm' could not be loaded. Ensure the assembly has been referenced and that all projects have been built.

Where can be a problem?

Start Menu Items and their click events

Hi all,

A very annoying issue that I hope I can get some help on. When I create Start Menu items and respond to their click events, if I have breakpoints in my code, the start menu sits on top of VS.

Not a huge issue, except that it sits over most of the menu items, so if there's a crash, I can't hit the button to force the app to stop.

Is there a way to force the start menu to close *before* it executes the event?

Thanks!

Rob.

[Solved] ListControl Drag&Drop with Descritpions

Hi,

I'm using the ListBox control with the Scheduler one, so when the user drags an item with description from the ListBox and drops it into the scheduler a new appointment is created. I saw the Demo you provide, however, this one uses plain RadListDataItem and RadListVisualItem. On the description of each item there's a phone number. I have created a new "Add Appointment" form to hold the phone number. My Question is: how can I Drag&Drop ListBox Items with descriptions and retrieve not only the Item text but the description too?

I've tried the following code, but "item" is always null.

Private Sub radListBox1_MouseMove(ByVal sender As Object, ByVal e As MouseEventArgs)
    If e.Button <> MouseButtons.Left Then
        Return
    End If
 
    If Me.isDragging Then
        Return
    End If
 
    Dim currentPosition As Point = e.Location
 
    If (Math.Abs(currentPosition.X - Me.mouseDownPosition.X) >= SystemInformation.DragSize.Width) OrElse (Math.Abs(currentPosition.Y - Me.mouseDownPosition.Y) >= SystemInformation.DragSize.Height) Then
        Me.isDragging = True
        Dim dragObject As New DragObject()
        Dim item As DescriptionTextListVisualItem = TryCast(Me.LBox1.ElementTree.GetElementAtPoint(e.Location), DescriptionTextListVisualItem)
 
        If item IsNot Nothing Then
            dragObject.Values.Add(AppointmentFields.Summary, item.Text)
            dragObject.Values.Add(AppointmentFields.Description, item.DescriptionText)
 
            dragObject.Status = AppointmentFields.Summary
 
            TryCast(sender, RadListControl).DoDragDrop(dragObject, DragDropEffects.Copy)
        End If
    End If
End Sub

Thank you very much for your time and attention,
Matias.

[Solved] Cannot use ContextMenuStrip which has submenus in autohidden windows

Hi,

I have RadDock with docked window to the left side. State of this window is auto-hidden. This window has one control RadTreeView which has assigned ContextMenuStrip. This ContextMenuStrip have menu with sub-menu items.
In this case when I open menu and click at any sub-menu item (level 2 or deeper), my window hides, and event from menu item isn't fires. I'm using Controls from Q3 SP1

P.S. If I click at pin button, to avoid window auto-hide, then everything works well.

What should I do? Is there a workaround for this issue?

DateTime Axis?

Is there a DateTimeCategorial Axis for WinForms implementation of ChartView? I'm bringing in a DataTable who CategorialValue is a field that's a date, but it's sorting it as if it's a string.

Also, after upgrading to Q2, I seem to no longer have "RadChart" in my toolbox. Would really like to go back to using RadChart based on how extremely limited the functionality of ChartView is.

Thanks

Rob.

Assign Value to tooltiptext

Hello,
I fail to assign a specific value to the tooltiptext of a drop down list,
in the past I used the Tooltiptextneed event as follows
:
    Private Sub ddCountry_ToolTipTextNeeded(sender As Object, e As Telerik.WinControls.ToolTipTextNeededEventArgs) Handles ddCountry.ToolTipTextNeeded
        e.ToolTipText = ddCountry.SelectedItem("Label")
    End Sub

But is seemed to be not working anymore

I tried the following:

    Private Sub ddCountry_VisualListItemFormatting(sender As Object, args As VisualItemFormattingEventArgs) Handles ddCountry.VisualListItemFormatting
        args.VisualItem.ToolTipText = ddCountry.SelectedItem("Label")
    End Sub

But the selected index seems to be always "0" ant not the index of the Item on which I want to set the tooltip

How Should I set the tooltiptext to display the desired text ?

Thanks in advance
