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 currently have both DGV.CellMouseClick & DGV.CellMouseDoubleClick implimented in my code.The DGV.CellMouseDoubleClick never fires and the DGV.CellMouseClick always fires. The only exception is when I position the cursor between DGV cells and get the double arrow. If I double click with the double arrow then I get the DGV.CellMouseDoubleClick to fire
View 7 RepliesI create Context menu at runtime depends of text in selected cell of datagridview.
Like this:
With ContextMenuStrip1
.Items.Clear()
Dim Str As String = DataGridView1.Item(1, DataGridView1.CurrentRow.Index).Value

And as vbnet beginner with this code I can't get text of fired menu item in event handler.
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.
View 6 RepliesI've got a contextmenustrip with a couple levels of dropdowns (submenu items). Let's say I right-click the form and show the "main" set of items, one of which is "Food". If I move the mouse over Food (not click it), a dropdown (submenu) for Food should open, which it does. But then, say, one of the food items is "Fruit". When I move the mouse over "Fruit", the Fruit submenu should open automatically - but it does not always - sometimes it does, but sometimes I have to click it to open it. Furthermore, once "Fruit" has been clicked once to open, any other dropdown items (let's say we had "Veggies" and "Meat") will automatically open as I expect; and then "Fruit" will behave as expected also.
Any ideas on how to correct this inconsistent behavior? (i.e. all sets of dropdowns associated with a contextmenuitem should open when the mouse is moved over it, a click should not be required)
At design-time I have added the ToolStripItems to the ToolStripDropDownButton but I want to provide a Context Menu which has the same items but when I am adding the items to the ContextMenuStrip at runtime they are removed from the ToolStripDropDownButton and are only available to the ContextMenuStrip already, is it not possible to have them in both ToolStripDropDownButton and ContextMenuStrip?Rather than duplicating the menus I would have preferred utilizing them in both ToolStripDropDownButton and ContextMenuStrip.
View 2 RepliesI'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.

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?
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.

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.

I have a listbox binded to a list of objects. For each list item I wanted to have a rectangle whose fill color is determined by a few properties of the binded object. So I did the following:
Made sure INotifyPropertyChanged was implemented on my object.Created a class to expose the properties I am interested in as attached properties.Binded the properties of the object to the attached properties of the rectangle Created a style that uses triggers to set the rectangle fill based on attached properties.
This works, but only the first time the property of the object changes. After that, the attached properties do not seem to be receiving notification when the data object's property changes. I have double checked and my data object is raising the INotifyPropertyChanged event.
<Rectangle Style="{StaticResource RecordStateRectangleStyle}"
Width="10" Height="10" Stroke="Black"
local:RecordAttachment.RecordState="{Binding Path=RecordState}"
local:RecordAttachment.IsDeleted="{Binding Path=IsDeleted}" />

Can i Know how to catch between these 2 event, Leave and Click?
I have one checking in a textbox Leave event. I will go check whether this ID is already exist in DB or not. If exist, I will prompt MSG box to user.
When I click on Close button while focus is on textbox, this textbox Leave Event will trigger first before Button Click event.
So, the form remains open without trigger Button Click event.
how to prevent this textbox leave event or how can i catch/control this situation?

Within a private function in SomeObject, I would like to run some logic (including firing the StatusChanged event) in the event that Status has fired its StatusChanged event. I have been away from events for a while so it's a bit cloudy to me. How do I do this?

View 6 RepliesI think know how to do this in C# but I'm having syntax trouble in VB.NET because I need to take advantage of the 'handles' event stuff. I have different events that I somehow (probably delegate) need stored in a property of an attribute (I just add an attribute to a property linking to the corresponding event).
E.g.
<BindEvent(EventThing)>_
Public ReadOnly Property IsTrue() As Boolean
Get
Return True
End Get
End Property
They need to be events so that other programmers can use the VB.NET handles keyword on methods.
Public Delegate Sub TestEvent(ByVal sender As Object, ByVal e As Object)
Public Event E As TestEvent
Public Sub Test() Handles E
End Sub
These properties are already raising a general event, which I am catching, determining the related property and thus getting the related attribute (and delegate/event). I want to then raise the event that's related. If I just use a delegate tied to the particular event that won't raise other handlers will it? I also want to avoid having to write a sub for each property that just uses Raise Event on the event type if possible as this seems redundant.
E.g. avoid:
Public Event E As TestEvent
Public Sub CallE(ByVal sender As Object, ByVal e As Object)
RaiseEvent E(sender, e)
End Sub

I'm recreating a program (don't ask - it is embarrassing) in Visual Studio 2005 VB where I read a spreadsheet in an then select values from certian rows. I added the Interop reference and the MS Excel 14 object library, but when I type something like:
Public oSheet as Worksheet
...
x=oSheet.Cells(Row,1).Value.ToString
I'm concerned because when I type the period after the ) it does not allow me to select value. I type it in and it does not give an immediate syntax error but I'm guessing that when I try to run this, it will fail the build. Is there an other reference I need to add or do you get the value of a field differently for Office 2010 than we did for Office 2007?
