ContextMenuStrip On DataGridView?
Sep 27, 2009
I am formerly a VB6 programmer learning the .Net world of VB2008. I am confused and need assistance with the following.I am attempting to get a ContextMenuStrip to work on a DataGridView. I want my program to add the ContextMenuStrip and fill in its menu items. I would then like a right-click on a menu item to take me to a unique click event to handle the specific menu action.The example below is a simple form with a datagridview (1) and contextmenustrip (1). I could not get it to work without adding the ContextMenuStrip control manually.

I'm trying to show a small DataGridView in my ContextMenuStrip that I have built. The DataGridView will show a unique list of values in a DataGridViewTextboxColumn "Sample ID" when its column header is right-clicked. I can get the unique values just fine, but I'm having trouble displaying the small DataGridView in the ContextMenuStrip. It currently looks like this.Notice, there is no data in the DataGridView. I have confirmed that the DataGridView.DataSource has several rows in it, yet the DataGridView shows nothing. Plus, I need to increase the size of my DataGridView, thus increasing the size of the ContextMenuStrip to show the DataGridView.
Public Class ContextMenu_Column_String
Inherits ContextMenuStrip
Private dvs As DataGridViewSettings

I'm trying to show a custom contextmenustrip on my datagridview and it works fine except when the cell is being being edited. Then it shows the default windows contextmenustrip with copy/cut/..Is there a way to overwrite the DataGridViewTextBoxCell contextmenustrip or disable it? The solution from Disable DataGridView System ContextMenu does'nt work for me.
Private Sub DataGridView1_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DocCostGroupDetsDataGridView.MouseDown
If e.Button = Windows.Forms.MouseButtons.Right Then
_CustomContextMenuStrip.fGetContextMenu()

find the underlying DataGridView (DGV) when responding to a Right Click on a ToolStripMenu (TSM).I have several DGV's all using the same ContextMenuStrip (CMS) [DGV.ContextMenuStrip=CMS]I have six ToolStripMenuItems under the CMS. I thought I could just add a unique handler for each of the ToolStripMenuItems and be a happy camper on each Right Click...But I cannot figure a way to decode the underlying DGV. There doesn't seem to be any relationships between DGV and TSM and none between CMS and TSM.Is this path a dead end? If so how should one do it? FYI my DGV data is unbounded.

If you assign a ContextMenuStrip to the DataGridView.ContextMenuStrip property and then right-click a cell, the CellMouseClick event doesn't fire. Why would the ContextMenuStrip block this event from occurring?
My workaround at the moment is to separate the ContextMenuStrip from the DataGridView and show it with code, but this seems unnecessary.

So I have a bit of a problem and maybe I'm going about it in the wrong way UNPOSSIBLE! :-D
All I'm looking to do is create a few popup menus using contextmenustrips, it seems reasonable enough to me. What I want to happen is when I mouse over a label I want it to open up the contextmenu and THEN close once I am off the label and the contextmenu strip WITHOUT having to click the form. so I can go up and down a set of labels and popup menus as I move the mouse over each. This has turned out to be much harder than I anticipated. :-o
So at first I though ok lets try this code below. But this just causes the menu to flicker I "thought" focus would go to the contextmenustrip but i doesnt seem that way
Public Class Form1
Private Sub Label1_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles label1.MouseHover
ContextMenuStrip1.Show(Label1, 20, 0)
End Sub
Private Sub Label1_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles Label1.MouseLeave
ContextMenuStrip1.Visible = False
End Sub
Private Sub Label2_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles Label2.MouseHover
ContextMenuStrip2.Show(Label2, 20, 0)
End Sub
Private Sub Label2_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles Label2.MouseLeave
ContextMenuStrip2.Visible = False
End Sub
End Class
So then I thought ok well I'll just try to have it where when I leave the contextmenustrip I'll close that. THIS WORKS but not exactly how I want it to I can hit a label then jump onto the menu then off to another label but cant go label to label up and down the form.
Private Sub ContextMenuStrip1_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ContextMenuStrip1.MouseLeave
ContextMenuStrip1.Close()
End Sub
Then I thought ok well how about something like
Private Sub Label1_MouseHover(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.MouseHover
If Label1.Focus Then
ContextMenuStrip1.Show(Label1, 20, 0)
Else
ContextMenuStrip1.Close()
End If
End Sub
But that didnt work either, I have another vb.net guy with me and hes all *shrug* I'm probably just going about this in the wrong way your suggestions are welcome. Thanks mucho everybody

I have a windows form application that has two tabs on it. On each tab there is a RichTextBox which i want the user to be able to copy, paste etc from within.I have tried to set this up but am finding that when i paste anything into the RichTextBox1 it is also copied into the RichTextBox2 on the second tab?My code is below, can you spot any errors with this? I only have 1 ContextMenuStrip within my form, should i have more than this?
Private Sub PasteToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PasteToolStripMenuItem.Click

I have a lowlevelkeyboard hook in my program. The keydown event checks the active window title to see if a microsoft word document is open, and when the letter 'y' is pressed a contextmenustrip is called. Everything works great except for the arrow keys. When the contextmenustrip is visible, the arrow keys will not select or move through items in the contextmenustrip. I set up some IF statements to check if the contextmenustrip is open, and when it is the up/down arrow keys select the next item in the menu. The problem is that the word document has actual focus and the up/down keys are still sent to the word document (causing the line the cursor is on.)I have tried using e.suppresskey in the keydown event to try to prevent this, but the keys are still pressed on the word document.

In vb.net (2008), I want to be able to control when a contextMenuStrip (context menu) is displayed. I don't want it to always appear when the right mouse button is clicked...only when certain criteria within my program are met. I figure I would use addHandler but I'm not exactly clear on how to completely control the opening of the contextMenuStrip. I know I would issue a call to the "open" method to render the contextMenuStrip. However, I am unclear as to how to completely take over control of when to render the contextMenuStrip.

Is there an event that fires in vb.net just before a contextMenuStrip appears when the user right clicks on a control? I need to be able to control the content of the contextMenuStrip just prior to the menu strip appearing. Basically I want to be able to change the content of the contextMenuStrip just before it appears.

I'm working in .NET 2008 trying to toggle the visbility states of subitems on a form-designed contextmenustrip. [code]Depending on the user's installed hardware, I may want to hide subitem1 or subitem2 because it is not relevant to that user. I am sort of a beginner at this, I can't figure out how to access the subitems' properties programmatically. I am not sure what I was doing before but I sat down again this afternoon and rewrote my code and it worked fine.

I'm trying to have my NotifyIcon show the native context menu of the Operating system. When I use ContextMenuStrips they have the custom skin made from Microsoft which I dont want. I want to use the original menu that all other applications use on my computer. How Can I use that menu? I have tried using the "old" ContextMenu control but It doesnt work with NotifyIcons, it only displays with other controls.

I have single ContextMenuStrip attached to more controls.In use the Opening event of ContextMenuStrip to filter/disable some context entries.In this case the property ContexteMenuStrip.SourceControl is set correctly.The problem I have is on the Click event of a ToolStripMenuItem. This item is inside a ToolStripDropDown. I get the parent item with code:
Dim tsmi As ToolStripMenuItem = DirectCast(DirectCast(DirectCast(sender, ToolStripMenuItem).Owner, ToolStripDropDown).OwnerItem, ToolStripMenuItem)

I am trying to build a context menu for a little "random quote" generator project. Most of the context menu for the NotifyIcon I can create at design time, but I need to create a submenu of file names that the user can choose (check) to be included in the quote population.
I originally did this in VB6 and it worked, now I get a Null reference error. The problem occurs in the Sub BuildChooseFilesMenuItems. Code follows. (Basically, I need to read in the filenames, make them menuitems and keep track of their "checked" state. It is dynamic because the user could add new quote files to the directoryy where they are stored.

Option Explicit On

When creating a right click (ContextMenuStrip) menu for a systray (NotifyIcon) icon, how do I give it the same style as most other context menus? Most other menus have a nice fade inout when right clicking on the system tray Icon. In addition they respond immediately when moving between nested levels. I cannot replicate this in Visual Studio 2008 using a simple form, NotifyIcon and ContextMenuStrip assigned. The menu appears harshly with no fade effect regardless of any property.

I have a context menu strip associated with a listview. Everything work just fine however one of my menu options on the context menu strip has a pop-out menu (you know, you hover over the selection, and another menu strip expands out).I can seem to get these to work correctly.
Public Sub ReleasedToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ReleasedToolStripMenuItem.Click
FileEntries(ListViewSelectedIndex).Status = "Released"
[code]....
So I changed my sub to read as the one VB created, and still didnt work. So I went back to edit the context menu, double clicked "Reserved" menu items, then VB creates a sub w/o the _1 (like I had before).Also the check-box status for these menu items works fine.
