how to add further items to a dropdown control on the ribbon.
So far I have been able to create a number of items manually and then afterwards change the label of these items using
Globals.Ribbons.Ribbon1.DropDown1.Items(i).Label
Furthermore I found that some recommend using this to add further items to the dropdown control. But I am having a hard time trying to understand how to use it.
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)?

I am getting the following error while i submit a form after i added a dropdown box in my designer

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.

i am making a table through vb.net code (htmltablecell, htmltablerow..) no this table populates with an sql query and works perfectly. but inside this table in one tablecell, i need to add a dropdownlist which shall require a completely differernt query and shall run on its own on each row. so the code is as follows
Sql = "..." rd = ExecuteReader(SqlCnn, Sql) Dim newcounter As Integer = 0 While rd.Read()
[code]....
the ??? in the code is where the dropdownlist shall get populated each time with its own datareader and while loop and query.
I somehow lost a MenuStrip & StatusStrip from my form. Now I have all these MenuStrip items in the dropdown box of my properties window & I can't seem to delete them.
I'm making a program that uses recursion to transform the nodes in a treeview to the items in a contextmenustrip. The nodes will have tags within them that when I add a handler to the menuitem, it will run through a script from the tag to tell the program what to do, the only problem is that I don't need a tag or an even handler for any of the menuitems that have dropdown items. How could I do this?
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?
I have multiple combox boxes, A B C Combobox B has items Fruit, Veg, Dairy Combobox C needs to contain 3 list and depending on what value is selected in Combo Box B.

Using VB.NET I created an excel sheet with list of items in dropdownlist.[code]But i can able to view the listbox upto "testing", rest of the items are not diplayed in the listbox why?Is there any limit for dropdown list items, If so how to increase the limit?
ok, i've been able to figure out that i can add a button to a menubar (like the file edit view, ones at the top of most programs) and so far i have figured out:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click form1.MenuStrip1.Items.Add(TextBox1.Text)
I have a ListBox1, a Button1 and a DataGridView1 How can I achieve, than everytime I push the Button1, the items from ListBox1 will also reveal in the DataGridViewComboBoxColumn's dropdown menu.... I'm using Visual Studio 2010.
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.
Private Sub PopulateLoadChildMenu() msItemLoad.DropDownItems.Clear() Dim fi As FileInfo
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?
The dropdown box displays all the items previously added to that column.
I want the user to be able to enter a new value OR just pick a previous value from the dropdown list. (This is when inserting a new row)
Problem:
Whenever I enter a value, it jumps around in my table like its on acid or something. Whenever I select a value from the list, it takes me to the line in which the value was originally entered.
I am dynamically creating and adding dropdown controls to DevExpress XtraGrid.That works fine and I can add a dropdown control to any column I wish.My main problem is that I need to have the first element in the dropdown control displayed. But after I dynamically add 3 dropdown controls to the grid, only the last one has the element displayed. The previous two do not.Although, I add the elements
this is what the code looks like:
vb.net Dim column as DevExpress.XtraGrid.RepositoryItem.GridLookupEdit For i as Integer = 0 to dsSometing.Tables(0).Rows.Count - 1 column = New DevExpress.XtraGrid.RepositoryItem.GridLookUp
[code]....
The code will go tru and add lets say 3 dropdown controls, set their .DataSource to datasets I need, but it will only show .NullText of the last added control.
I need to load a large txt file that is in a fixed width format. There are over 45K lines, so speed is important.I need to load one of the fields into a dropdown box and have another field (label) display the text of another field in the related line.I could import the file to an access db if needed, but would rather not as i also want the txt file to update from a link on a regular bases. So having it in a DB would be more work to process that part.[code]
I added a few items in the combobox dropdown list at the form load event. [code] At the runtime I dont want to allow the user to write something in the combobox as a text.The user can only select an item from the dropdown list of the combobox.
I have created multiple dropdown list at runtime and populated with data. I also have added an eventhandler to determine the selected value of the drop down list.
The code is as follows : Dim tbl As New Table() tbl.EnableViewState = "true"
I have a list of servers in the first dropdown. I want to get list of all databases in the second dropdown depending on the server selected in the first dropdown.
For this I need to query each server while selecting the server.
I'm learning how to add items from a list box to a combo box. I'm trying to follow what's going on in the function loop and comparing a boolean and selected index. I can see that it's comparing the item chosen to each item already in the combo box to make sure that it's not already there. If function finds that it's not in the list it sends back that it is true that the item is not in the list.
It then continues to the statement that adds item to the list. The code for the double click event is working fine and items are getting added to combo box. However, the code for the add button isn't functional. I'm not seeing why it doesn't work? I coded out the original code, and replaced with something I thought might work but it still isn't functional. [Code]
