VS 2008 Dropdown Box Displays All The Items Previously Added To That Column?
Apr 30, 2010
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.
How do I get it to do what I want.

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 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?

Here's the issue in a nutshell (I can elaborate if you feel it's needed). In a DataGridView I want to capture the value of the row's key column so that when the user clicks on a column header to sort the data, I can reposition to the row that was selected prior to the click. The problem is that the sorting itself, once it's done, fires the same events (RowEnter for example) that I used to determine my key value, so it sets my variable to a new value and now

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'm trying to create a datagridviewrow and add data to it at runtime. I want the row to have the cells correspond to the columns in a datagridview, so that when I add data to the cells i can call the column name (the columns are likely to change around, so i think the name is better to use then the index).I create the row using the following code:
Dim row As New DataGridViewRow
row.CreateCells(Datagrid)
and the column using the following code:
Dim col As New DataGridViewComboBoxColumn
col.HeaderText = "Reference"
col.Name = "Reference"
datagrid.Columns.Insert(0, col)
I would like to add data to the row via the following code (or something similar that uses the column name instead of the index:
arow.Cells("Reference").Value = Detail.Reference
However at runtime I get the exception Column named Reference cannot be found. Parameter name: columnName I have a sneaking suspicion that the cells cannot be accessed with the column name because the row isnt really attached to columns yet (the row hasnt been added to the datagridview yet. (I tried cloning the cells of a row and then adding them to the row but no success)?

I have some combo boxes which displays one column of one database, and I want to trigger a query to it every time the CBox is changed, but as soon as the dialog with the cboxes opens, triggers itself..
Private Sub cbProd2_SelectedIndexChanged(sender As System.Object, e As System.EventArgs) Handles cbProd2.SelectedIndexChanged
'MsgBox("Changed")
txtQtd1.Text = "2"
End Sub
[Code]...
To test it I used the MsgBox and everytime the form opens it triggers the Msgbox 3 times each combobox.
I tried with SelectecIndexChanged and SelectedValueChanged but none of them worked good (I tried both isolated, one at time)

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.

Option Explicit On

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.
Globals.Factory.GetRibbonFactory.CreateRibbonComboBox.Items.Add
I would like to see a sample of how others have done it.

I only want the Me.TestHTTPSUploadToolStripMenuItem to be added if a boolean is true. How would you put an if condition inside this AddRange method?

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?

how to use #ZipLib. I've tried there forum and I've looked on this and other sites . I'm still new to VB and trying to teach myself. Using items like a text box are easy but i don't know much about how to use added items such as #ZipLib. Examples of compress and decompress would be wonderful but if you show me what can that would be great too.

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?
