.net - Control When A ContextMenuStrip Is Displayed?
Apr 9, 2010
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.

I've made a ContextMenuStrip to use in my program to change the image in a picture box. However, it's used with multiple picture boxes which each need to have their own changed. What I want to do is make my command change only that picture box leaving the others as they were before. An example, if this were a plausible code.
Private Sub TestToolStripMenuItem_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TestToolStripMenuItem.Click
Self(aka the control that currently has the menu open).Image = My.Resources.Picture
End Sub

I'm using a ContextMenuStrip for multiple controls and I'm trying to figure out the best way to get the control that was actually clicked on to open the Context Menu. The sender just gives the ToolStripMenuItem reference, which has an Owner property that references the ContextMenuStrip, but I cannot figure out how to tell which control the click came from. There must be a simple way to check this, right? I'm checking it in the ToolStripMenuItem's click event.

I found a similar post about this, but that mentions using a SourceControl property which I do not see on here.
I'm using Visual Studio 2008, VB.Net winforms.

What I'm trying to do is make my own contextmenustrip for the web browser control, this menu has two items so far: "Select All" which will select all the text displayed and "Copy" which simply copies whatever text is highlighted or selected. No images are displayed so no need to worry about that.
Also I've noticed that whenever a file is dragged from windows and dropped onto the web browser control on my form, the browser simply displays the file (these are xml files that I'm dropping on the control, on my form) which is not what I want it to do, instead I want to grab the file path & name and use it elsewhere. The browser control doesn't have the DragEnter, DragDrop, DragLeave events like labels, forms, textboxes, etc... how would I handle this?

Does anyone know how to choose the visualization displayed in the axwindowsmediaplayer control? I'd like the Bars, from the Bars and Waves section to always be displayed and not the last one I selected when I ran Windows Media Player on it's own.

Using a Windows Form with a Menu bar and a Gridview control, I have bound data to the GridView from an MS Access 2000 database query using Dataset. The contents of this table displays just fine. But I want to be able for the user to select a different query from the menu bar and display it in the same GridView control. How can I change the query bound to the control (in VB)?
Public Class Actinide Private Sub Minerals_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Actinide_Series__Radioactive_TableAdapter.Fill(Me.Minerals2000DataSet._Actinide_Series__Radioactive_) End Sub Private Sub LanthanideToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LanthanideToolStri
[code]....
The error message that it is giving me is:
"Value of type 'Mineralogy.Minerals2000DataSet.Yttrium_MineralsDa ta Table cannot be converted to
'Mineralogy.Minerals2000DataSet._Actinide_Series__ Radioactive_Data Table'.
The query is getting information from two seperate tables,so I can't just bind a table to the control and then filter what is displayed using SQL.

Writing a dice based game, the dice represented by pictureboxes when clicked are highlighted and their border style changes FROM BorderStyle.none TO BorderStyle.FixedSingle, which is where I want to increase the thickness of the border. My user control code increases the border thickness using the code below:-

I'm developing a windows application. I have a form in which there is a list box and a treeview control. My purpose is to fill treeview according to list item clicks. This is done using a pair of subroutines called ReloadPermissions and FillMenuItem:
Private Sub ReloadPermissions()
Dim p As New Permissions
Dim i As Integer
Dim it As TreeNode
Dim el As New List(Of String)
[Code]...
There are only two subroutines in which nodes are added to treeview control, and they are subroutines above. The problem is that whenever list item is clicked, node count displayed in treeview is increased!!! I checked number of nodes before and after call to tvPermissions.Nodes.Clear() using MsgBox. Results show that number of nodes isn't increased (1 before call, 0 after call, again 1 after ReloadPermissions() is called), but what is displayed doesn't show such a behavior! Refreshing window by putting it under other windows or call to tvPermissions.Refresh() has no effect.

I wrote a VB.Net application that displays HTML help files according to user's search results.A user types some keywords and receives a list of HTML help files containing these keywords.When a list item is selected the HTML file is displayed in WebBrowser control.The problem is that I cannot mark the keywords in the displayed HTML file. I need to highlight them like in a standard Help. I tried many options and nothing works.If I change HTML element style manually (background color for a specific string) all pictures attached to this page are not displayed. After "Refresh" operation the pictures are displayed but the text selection is not enabled.I hope there is a standard function for this operation but I cannot find it.

I'm looking to put a few labels on a form but the text that they will display will not be static. Instead they should be dynamic as the values used will be either the value of a specific Environment variable or from a value stored in an array. These values will change depending on which user runs the application. How do I achieve this?

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 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 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.

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.
