Add A Button To A Ribbon Group DevExpress - winforms

How can I add a button to a my ribbon group programmically? Here is my code so far that successfully Adds a new ribbonPage, then Adds a RibbonGroup to the page. But I need to add buttons to the ribbonGroup and its not working for me
Imports DevExpress.XtraBars.Ribbon
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim menu As New RibbonControl
Dim aPage As New RibbonPage("Nicks Page")
'groups
Dim aGroup1 As New RibbonPageGroup("1st Group")
'ADD BUTTONS TO RIBBON GROUP HERE
aPage.Groups.Add(aGroup1)
menu.Pages.Add(aPage)
Me.Controls.Add(menu)
End Sub

You will need to make a new button for the ribbon control as such:
Dim newButton As New DevExpress.XtraBars.BarButtonItem
Then add this to your Ribbon Page Group
aGroup1.Container.Add(newButton)

wpf richtextbox in winforms application

I would like to use a WPF RichTextBox in a WinForms project written with VB
I have created the WinForms project with one form and a button
I then added a new project WPF User Control Library placed a WPF RichTextBox on the WPF form
I added ElementHost interoperability to the WinForm with these Imports
Imports System
Imports System.Windows.Forms
Imports System.Windows.Forms.Integration
From here I am lost some of the SO question are 10 to 7 years old the MS tutorial is not much help
Code from WPF Form
Public Class UserControl1
ReadOnly rtbWPF As New UserControl
ElementHost
wpfwindow.Show
End Class
I did not post the XAML code NOT sure how to do that
So the question what to do next to link the WPF form with the RTB to the WinForms form?
I would like to load data from a SQLite DB into the WPF RichTextBox and save the text entered in the RTB into the DB
This answer is meant to expand on #KyleWang wonderful answer
One BIG issue with Vectors choice of the WPF RichTextBox is There is no Text property in the WPF RichTextBox control. Here is one way to get all of the text out. That said I would IMHO would suggest using the WPF Plain TextBox control
Vector also commented on how to hide the HotReload in the title bar
Tools > Options > Debugging > General > un-check Enable UI Debugging Tools for XAML
OK Code Below hope this is helpful if you decide to use a WPF control in WinForms for spell checking
Public Class frmStart
Dim rtb As Windows.Controls.RichTextBox = New Windows.Controls.RichTextBox()
Dim tb As Windows.Controls.TextBox = New Windows.Controls.TextBox()
Dim str As String = " "
Private Sub frmStart_Load(sender As Object, e As EventArgs) Handles MyBase.Load
ElementHost1.Child = rtb
rtb.SpellCheck.IsEnabled = True
ElementHost2.Child = tb
tb.SpellCheck.IsEnabled = True
If str.Length < 100 Then
rtb.VerticalScrollBarVisibility = Windows.Controls.ScrollBarVisibility.Visible
End If
End Sub
Private Sub btnAdd_Click(sender As Object, e As EventArgs) Handles btnAdd.Click
str = "Plain WPF TxtBox"
tb.Text = str
rtb.AppendText("Heree is som mispelled txt se if the dictioary wrks more nonsense to see the scroll bar's will this word wrapp or is that rapp")
End Sub
Private Sub btnGet_Click(sender As Object, e As EventArgs) Handles btnGet.Click
Dim elementHost = ElementHost1
Dim wpfRichText = CType(elementHost.Child, Windows.Controls.RichTextBox)
Dim range As Windows.Documents.TextRange = New Windows.Documents.TextRange(rtb.Document.ContentStart, rtb.Document.ContentEnd)
Dim allText As String = range.Text
tbMsg.Text = allText.ToString
End Sub
Private Sub btnGTB_Click(sender As Object, e As EventArgs) Handles btnGTB.Click
Dim elementHost = ElementHost2
Dim text = tb.Text
tbMsg.Text = text.ToString
End Sub
To host a WPF control in Winforms, you can refer to the following two ways.
First, both of them need to add a ElementHost control into form.
Solution A:
Directly declare the wpf controls (using Windows.Controls)
Dim rtb As Windows.Controls.RichTextBox = New Windows.Controls.RichTextBox()
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
rtb.SpellCheck.IsEnabled = True
ElementHost1.Child = rtb
End Sub
Solution B:
Create a new User Control(WPF) and edit the content in "UserControl1.xaml" as follows.
<Grid>
<RichTextBox x:Name="richtextbox" Foreground="Black" FontSize="24" Margin="0"></RichTextBox>
<RichTextBox SpellCheck.IsEnabled="True" />
</Grid>
Then modify the code in 'form1.vb'
Private uc As UserControl1 = New UserControl1()
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
ElementHost1.Child = uc
End Sub

WPF Running a command on a windows form

I have a WPF Project to which i've added a Windows Form.
The windows form has a method runme(). But I'd like to call it from the WPF form.
Currently I've used
Dim wpfForm as new wpfForm
wpfForm.Show()
to display the the WPF form from a Windows form.
I'm not sure how to send a command back though.
I've tried:
Me.parent.runme()
But this gives me errors
The only way that I can think of to do what you are wanting is to create a Custom Constructor for your Winform and pass the reference to the Wpf Window to it. There appears to be no easy way to assign a WPF Window as an Owner/Parent of a Winforms Window.
Winforms Form
Public Class Form1
Dim myParent As System.Windows.Window
Public Sub New()
InitializeComponent()
End Sub
Public Sub New(parent As System.Windows.Window)
myParent = parent
InitializeComponent()
End Sub
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
CType(myParent, MainWindow).runMe()
End Sub
End Class
Wpf Form
Class MainWindow
Dim winForm As Form1
Private Sub Button1_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles Button1.Click
winForm = New Form1(Me)
winForm.Show()
End Sub
Public Sub runMe()
Me.Background = Brushes.Red
End Sub
End Class
Eventually what worked was to create an interface as suggested by Cyborgx37
Interface ILogOut
Sub DoIt()
End Interface
Class WinFormWindow : Implements ILogOut
Public Sub DoIt() Implements ILogOut.DoIt
MsgBox("Message Received!")
End Sub
End Class
You can then use the ILogOut interface to send a message to the Windows forms window from a WPF window

Handling onclick event of Contextmenu Menu Item on windows form

I have Windows Form App. I have added Context Menu that appear when you right mouse click over the listbox. But some reason I could not figure out how to catch onClick event for ContextMenu- Menu-Item. In also need to grab item index from the listbox while user click on menu-item. If I am clicking the left mouse button i would use lstCustomer.SelectedItems(0).SubItems(2).Text, but I am not sure would it be the same case or not when user right clicks over the item and pick menu-item from Context Menu.
Dashboard.vb
Public Class Dashboard
Private Sub Dashboard_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
LoadContextMenu()
End Sub
Private Sub LoadContextMenu()
Dim contxMnu As New ContextMenu()
Dim menuItem1 As New MenuItem()
Dim menuItem2 As New MenuItem()
contxMnu.MenuItems.AddRange(New MenuItem() {menuItem1, menuItem2})
menuItem1.Index = 0
menuItem1.Text = "Do Something 1"
menuItem2.Index = 1
menuItem2.Text = "Do Something 2"
Me.ContextMenu = contxMnu
End Sub
End Class
I'm not sure whether I understand exactly what you want to get. If it's all about action that handles the Click event you can do something like this:
Private Sub LoadContextMenu()
Dim contxMnu As New ContextMenu()
Dim menuItem1 As New MenuItem("Do Something 1", New EventHandler(AddressOf DoSomething1))
Dim menuItem2 As New MenuItem("Do Something 2", New EventHandler(AddressOf DoSomething2))
contxMnu.MenuItems.AddRange(New MenuItem() {menuItem1, menuItem2})
Me.ContextMenu = contxMnu
End Sub
...and events are:
Private Sub DoSomething1(sender As Object, e As EventArgs)
' do something 1
End Sub
Private Sub DoSomething2(sender As Object, e As EventArgs)
' do something 2
End Sub

Delaying opening of sub-menus in a menustrip

Our environment: Visual Studio 2010, c#, .net 4 client profile.
We have a Winforms application that contains a menustrip in its main form. The items of the menustrip contain both an image (64x64) and text. The main form also has a TabControl which contains 5 tabs. In the OnLoad() method of the main form, we hide the TabControl headers so that they are not visible and therefore not clickable. Instead, when the user clicks on an item in the menustrip, we switch the active tab.
However, our menus have many sub-menu items, and since we use the main menustrip to select the active tab, we would like the sub-menu items to appear only after the user clicks the menu item for a period of time, not instantaneously. Otherwise, whenever the user changes his/her active view (by selecting a tabPage), the sub-menus appear on the screen since he/she clicked a menustrip item that contains sub menus.
Is this possible?
I don't completely understand the rationale, but you can delay the display of a submenu using the MouseDown handler and sleep function, like this:
Private Sub FileToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FileToolStripMenuItem.MouseDown
System.Threading.Thread.Sleep(2000) ' wait two seconds
End Sub
======================
(Edit: Added second solution)
You can do this with a timer control and ShowDropDown/HideDropDown:
Private Sub FileToolStripMenuItem_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles FileToolStripMenuItem.MouseDown
' show tab here'
FileToolStripMenuItem.HideDropDown()
Timer1.Interval = 500
Timer1.Start()
End Sub
Private Sub FileToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FileToolStripMenuItem.Click
FileToolStripMenuItem.HideDropDown()
End Sub
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Timer1.Stop()
FileToolStripMenuItem.ShowDropDown()
End Sub

Cannot update a treeview inside a usercontrol

I created a usercontrol with a treeview inside it. The treeview will be populated if I add nodes in the onload handler of the usercontrol. But after that(for example, I click a button in its parent form), the treeview will not refresh. I can see the nodes was updated in memory, but it just cannot display on the screen. I called refresh/update after adding nodes. Any suggestion is appreciated.
I put a quick test together based on your description and it seems to paint just fine.
UserControl1
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class UserControl1
Inherits System.Windows.Forms.UserControl
'UserControl overrides dispose to clean up the component list.
<System.Diagnostics.DebuggerNonUserCode()> _

Try
If disposing AndAlso components IsNot Nothing Then
components.Dispose()
End If
Finally
MyBase.Dispose(disposing)
End Try
End Sub
'Required by the Windows Form Designer
Private components As System.ComponentModel.IContainer

Me.TreeView1.Location = New System.Drawing.Point(0, 0)
Me.TreeView1.Name = "TreeView1"
Me.TreeView1.Size = New System.Drawing.Size(150, 150)
Me.TreeView1.TabIndex = 0

'UserControl1

Me.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font
Me.Controls.Add(Me.TreeView1)
Me.Name = "UserControl1"
Me.ResumeLayout(False)
End Sub
Friend WithEvents TreeView1 As System.Windows.Forms.TreeView
End Class
Public Class UserControl1
Public Sub AddNewNode(ByVal text As System.String)
TreeView1.Nodes.Add(text)
End Sub
End Class
Put the usercontrol on a form with a button
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
UserControl11.AddNewNode(Now.ToString)
End Sub
End Class
If you are seeing proper painting as well then look at any graphics handling in the parent form then the usercontrol then the controls within the usercontrol. We really need more info.
Thank you, Dave. I figured it out. I put the usercontrol twice to my form by mistake(I cannot remember how I did it). And the one I operate is underneath the other one. That's why I cannot see it. Sorry for wasting your time.
