I have currently changed the color of background Menustrip using this code
[Code]...
How do i change the Hover color of menu items and dropdown menu items to orange including the background color which holds icons in menustrip dropdown.....
I have the following linq statement to go through a dropdown menu's sub items and get what items are checked: vb Dim UnselectedItems = From xItem As ToolStripMenuItem In tsiSelectObjects.DropDownItems Where TypeOf xItem Is ToolStripMenuItem AndAlso CType(xItem, ToolStripMenuItem).Checked = False
I get this error tho: Unable to cast object of type 'System.Windows.Forms.ToolStripSeparator' to type 'System.Windows.Forms.ToolStripMenuItem'. As you can probably guess i have ToolStripMenuItems and separators in there
However the AndAlso should short circuit in the case where the item is not a ToolStripMenuItem and it doesn't seem to be doing so (as TypeOf xItem Is ToolStripMenuItem=false in this case)?
My application is in VS2008 and coded in VB.net.
I have a datagridView(DGV) on one of my form.DGV contains a column of type DatagridViewComboboxColumn.I have another column of SrNo.
Consider Table1 to be the table from where my DatagridView is filled which contains following fields SrNo,Value1,Value2.
My requirement is i want to fill the values in my DatagridViewComboboxColumn from Table1.The DatagridViewComboboxColumn's combobox should contain values of columns Value1,Value2 of Table1.
Sample data of Table1
SrNo Value1 Value2
1 2 3
2 4 5
As data in datagridView is filled from Table1 the data of SrNo column of Table1 is also populated in one of the column of DGV.
Now my DatagridViewComboboxColumn combobox should contain the values of Value1 and Value2 of Respective SrNo.
Like Row one of my DGV has SrNo 1 as first value,so the Value1 and Value2 of SrNo 1 should be added to the row's DatagridViewComboboxColumn.
Select distinct Value1,Value2 From Table1 where SrNo=DGV.items(0,DGV.currentcell.rowIndex).value.H ope this Query willl make things more clear

I have on my form load to add items to a menu as a dropdown item.from within the same sub I try to output the menustrip dropdown items in a msgbox but I get a blank response for all my items.

I have my program set up to read the contents of a Directory, and then populate a drop down menu with the names of the files in the directory. (I am using the MenuStrip). Inside my program, it is also set up to create a new file in that directory, and I wish to add this item to the dropdown menu upon creation. The list is entirely created and populated from the code, and the contents of the list depend entirely on what's in the directory.
I have tried using MenuStrip.Items.Remove(menuItem1). Now, when this command gets executed, it does remove the top level Menu, however when I go to repopulate the menu, I end up with duplicates of my files listed in the drop down. I am stuck with how to clear these out as well?
I added a setting in my.settings, the setting is a listbox, and I know you can put controls in a listbox, but for some reason it will not let me add a toolstripmenuitem to the listbox in my settings. Is there a fix to this?
View 5 RepliesI am developing an MDI Text Editor, well more like upgrading my standard text editor, I am trying to re-code the menu items cut, copy, paste and so on.I have written this sub routine for the "cut" click event handler
Private Sub CutToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CutToolStripButton.Click, CutToolStripMenuItem.Click
Form2.RichTextBox1.Cut()
End Sub
Form2 being the form I designed for my child forms, the idea is that the menu control is used by Form1 the parent form, I thought that if the cut menu item looked at the RichTextBox in form2 then it would cut the line of text. it doesn't work?
Ive added items to my menu strip, cut , copy , paste etc. but i dont know how to code them im using a tabbed web browser incase that makes a difference

View 2 RepliesI have a listbox control on my form that has SelectionMode as MultiSimple so I can select more than one item with my mouse. I added a contextMenuStrip to my form and added it to my listbox. I'd like the user to be able to select a few items in the listbox and when they right click > Copy it would copy the contents of the selected items to the Clipboard.

I'm unable to copy/paste items from my listbox to any document (Excel, Word, .txt). I would need to select multiple items in the listbox. I searched for it but there seem to be multiple vague answers around there.
View 1 RepliesI am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

I have a DataGrid, with several columns. One of them is DataGridViewComboBoxColumn. I have a lot of items in this column - more than 1000 - and I need all of them. So grouping is not an option - all items must be there, users must be able to select from all.The problem is, DataGridViewComboBoxColumn becomes painfully slow, when number of items is about 1000, and above. This issues is well known to Microsoft, it dates back to Visual Studio 2005: [URL]...The problem is still present in Visual Studio 2010. Any ideas how to solve this?
Is it possible to fill DataGridViewComboBoxColumn with data partially? I mean (that was functionality fully working in Access), when you click DataGridViewComboBoxColumn, some items are displayed (lets say, 100 items). When you scroll down to the latest item, others are loaded (another 100) and so on. I don't see any other option to make DataGridViewComboBoxColumn working faster? Problem is, how to implement this? Has anyone meet that problem before?

View 2 RepliesUsing a DataGridViewComboBoxColumn, the goal is to make the ComboBoxes accept user's new items and also the possibility of choosing items that are already present.I'm aware of using EditingControlShowing event of the DataGridView to change the DropDownStyle of the DataGridViewComboBoxEditingControl at run time to allow this, but I'm wondering if this can be done at a lower level.
What I'm doing now is extending DataGridViewComboBoxColumn, DataGridViewComboBoxCell and DataGridViewComboBoxEditingControl, hoping to change the EditingControl's DropDownStyle in the moment I instantiate it. So far, no luck.The debugger shows the right assignment is being executed, but nonetheless, the DropDownStyle is popping at the EditingControlShowing (using the event for debugging purposes) as DropBoxList, not DropBox, which is the intent.
Here follow the classes:
Public Class DataGridViewComboBoxColumnALT
Inherits System.Windows.Forms.DataGridViewComboBoxColumn
Public Sub New()

I am trying to create a basic quoting tool but got stuck on how to clear and change the item collection from within a combobox for a datagrid.What we have is a list of 4 columns like a. Device b.TypeofService c.State d.Price Inside a sql database. Data is also structure like above as well.
I have a datagridview where the user will populate a,b,c and the price will be display and a total at the end. However a,b, and c aren't related in my current application. The combobox will show all possible dinstinct values for each column.
This works fine but I want to refine the application to only show the values of b. which are in the database after the user select the value for a. I have tried searching on how to do this as I assume to the Contry/State/City situation but could not find anything for a datagridview control in VB.NET.
Can anyone point me in the right direction? If I cannot do this dynamically from within a datagridview I was thinking of maybe creating three combo box outside and having it populating the datagridview afterwards but it wouldn't be as nice.
I have combed these forums and the 'net and can't find an answer to my specific problem. My menu strip disappeared (after deleting a small secondary form within my project). I therefore created a new strip and while recreating the menu items realized that the original menu items are still present, showing in my properties list. I have checked my design file as well and the original menu strip is definitely gone but the original menu items are there. I don't have many items so I would have no problem just deleting the original ones but I can't see them to delete them! I have checked and they are all set to visible. I have also moved everything on my form to see if it is behind anything else.

I'm trying to make a user control similar to the Windows Vista/7 breadcrumb bar used in windows explorer. However, when I show the drop down menu for a breadcrumb with many sub items, I get a very long list that sometimes exceeds the screen size. In the Windows Vista/7 example however, there are a maximum of 18 items displayed at a time and a scrollbar appears at the right when the number of sub items exceeds this number (18).
