Host A DataGridView On A ContextMenuStrip Using ToolStripControlHost?
Apr 27, 2012
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 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 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.
I am trying to remove the white space around a toolstripcontrolhost control which hosts a calendar control in a contextmenu. See the attached image and code.
VB: Dim menuItem As ToolStripMenuItem = New ToolStripMenuItem("MyMenu") Dim calControl As New MonthCalendar
I hope you'll humor me with this, but I can't wrap my brain around it. I am attempting to add a ToolStripControlHost(DateTimePicker) to a MDIParent form, which will be used to call a method which shows the Child form(s). I have no problem with the adding the DateTimePicker, the showing of children, etc., but how to call the method from event(.ValueChanged?) of ToolStripControlHost? Despite much Googling and reading I'm not very clear on the entire event handler code. The following is where I currently am:
I'm using VB2008 Express. And I've been working on a "popup" to select a date range. The DateTimePicker isn't ideal because the purpose is to pick a date range, which will always be one full week, from Sunday through Saturday. The control works just fine and I'm pretty proud of it. My problem has to do with the border added when using ToolstripControlHost for this. I've included a screenshot and my code.
In the code below, assume there exists a button named "btnTimePeriod", below which I desire to show a panel, which contains a few custom items, and the panel's name is "pnlDateRangePicker".IT WORKS... but it doesn't look right. The panel itself is 147 x 326 pixels, but notice in the attached graphic that it's adding a border around the panel which I don't want. There's a border on the top, bottom, and left... but for some reason the border on the right one is especially large. Although my code doesn't expressly set it, AutoSize = true so I would have expected it to shrink around the panel.
As required, my code already does set ShowCheckMargin and ShowImageMargin false. I haven't included the code for the DrawDateCalander Sub because it's not relevant. I believe even a blank panel would yield the same result. I have no idea where this margin is coming from.
Private Sub btnTimePeriod_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTimePeriod.Click Call DrawDateCalendar(DatePart(DateInterval.Month, FirstDisplayedSunday), DatePart(DateInterval.Year, FirstDisplayedSunday)) Call ShowControlBelow(btnTimePeriod, pnlDateRangePicker) End Sub
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 RichTextBox1.Cut()
first off all i have this form called bookingand in this form i have a datagridview called datagridv1and i placed a contextmenustrip to the formbooking from the toolboxHOW DO remove the label what is in de datagridvthrough the contextmenustrip that i attach to this labelthis my code
Private columnindex As Integer = Datagridv1.CurrentCell.ColumnIndex
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 a website has already hosted on EasyCgi (suppose that it's called website1). I have to host another one (website2). So I created a folder called "website2" under the website1 root folder. then I FTP all the content of website2 to the "website2" folder.
How can I dynamically create a host name in ASP.NET? Like if people come to my site, I want to be able to dynamically create them a .Mysite.Com host name. I've seen this done at other sites before but can't seem to find documation on how to do it.

I want to get the absolute host name from a URL that's in the format of a string. So far I have done it like this:[code]I need the host without the www for comparision purposes.If I have two strings "url...m" and "url...m" I'm interested in only seeing that they are both on the domain "url...m". Is there some fairly simple way to do this?
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)
Is it possible to add items to a contextmenustrip during runtime in a certain order?I have a program that is very flexible, it can do one instance to any number of instances of whatever, but I want the menu to be able to also display links to each instance.So like
I have made it so that as soon as the form opens it puts an icon in the tray and when you right click the icon it comes up with a contextmenustrip. in the form I have put a button and a textbox. when you click the button, it creates a new item in the contextmenustrip What I wanted to do was add a peice of code to this new item, is this possible?
