Hide Item In Combobox?
Jun 29, 2007
vs2005 -vbI have a combobox that gets its values from a call to the db. I have programatically added the list values for the box to match all the possible values that could be pulled from the DB. The user can update these values and update the db entry.I would like to be able to display any entries from the db, however, there is one value on the list that I don't want the user to be able to change the combobox's value to. I'm hoping there is some way to to 'hide' or '.visible=false' for just this one item when the list drops down so the user can't select that value.The box sits in a datagridview. I realize I could use the 'cellbeginedit' & 'cellendedit' events to prevent this action, but I consider that to be a last resort, as I think not showing it on dropdown is preferable code-wise.

I have used the command:
For Each Proc as process in process.getprocesses
Combobox1.Items.Add(Proc.MainWindowTitle)
to populate a combo box with the list of current process windows, however for every process that doesnt have a main window title there is a blank space, is there a way that I could tell it to not insert the item if it's mainwindowtitle field is blank?

Just started on vb.net
I have a combo box with "yes" and "no" with i select Yes i want the label2 to change the text to "yes" likewise with "no"
I've tried to code it in a logical way as possible but it just doesn't works except for the "wtf" so i think that overall my code is correct but the way i want to retrieve the selected item from combo box is wrong.
Public Class Form1
Dim aa As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As

my program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".
Now I just want to make 3 radio buttons:
- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).
How can I do so?
To download the entire list in the combobox I do:
Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)

I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

I want to hide an item in a combo box with out changing indexes of other items..the collection of the combo box is hard coded. ex: if I logged as a username ABC then combobox shouldn't have a item called ABC and want to remain other items' indexes as previous.
i can't use cbxOption.Items.RemoveAt(index) becouse indexes will change.

I am successfully hiding a combobox, based on the selection of another combobox. However, I can not get the label of the combobox to hide as well. The code I am using, which is basically the same code for hiding the combobox itself returns the following error:
Error 1 'DOCUMENT_EVALLabel' is not a member of 'WindowsApplication1.Form1'
Here is the code I am using for the label:
Me.DOCUMENT_EVALLabel.Visible = (EVALUATIONComboBox.Text = "Text")

I have a simple web for that has a dropdown list and a button on the form.The dropdown list is bound to a table in my database and holds three values with idents between 1 and 3 (Weekly,Monthly, Please Select).I have set my datasource to pull back item 3 (Please Select) as the first item in the dropdown list to prompt the user to select an option. Items 1 & 2 have data assigned to them and this pulls back the relevent data for these options.
Here is my problem. I need to hide my button when the page loads until the user selects item 1 or 2 and would like the button to be hidden of option 3 is selected. I have tried to complete this in my page load event and the code for the dropdown list but i cannot seem to get this to work.
If IsNumeric(DropDownList1.SelectedValue) = 3 Then
btnAddAgendaTemplate.Visible = False
End If

I'm writing a standalone application in VB.NET using Visual Studio 2005. I want to display/hide a bunch of Buttons based on the selected value of a ComboBox. Each selection would have a different set of Buttons to display, and I'd like to have them arranged in a nice grid.
Driving a TabControl with the ComboBox value would be the kind of behavior I want, but I don't want it to look like a TabControl to the user because it might be confusing.Is there a way to do this?
Basically, I'd like Selection1 of the ComboBox to show Buttons 1-4, Selection2 to show Buttons 5-11, Selection3 to show (maybe) Buttons 1, 3, 5, 6, and 8, etc., have them arranged nicely, and have the GUI show only the ComboBox and the buttons.

Normally to add a item to a combobox I just do:
<option value="310">Willmington (310)</option>
But in a vb.net 2008 I am working a windows app to do the same thing, and for the life of me cannot figure out how.This is what I have currently.
While Reader.Read()
frmMain.cboType.Items.Add(Reader("TypeName").ToString)

In vb6, to add a combobox item, you simply say:
Combo1.AddItem
All easy enough. But how do you do that in VB .NET?

I have a combobox that is bound to a dataset (via datatable and datatableAdapter). The combobox displays the current data in the table as it should.I have programmatically added the string "ADD..." to the list at the form.shown event:[code]when the user then click on (select) "ADD...", i open a new form to allow the user to add a new item to the list.The code i have behind the "ACCEPT" button on the new form stores the NEW value to the DATASET. I have verified this by previewing the data in the dataset.My problem is getting the combobox to reflect the changes to datatable to which it is bound.[code]
