Change List Of Combobox A Based On Item Chosen From Combobox B?
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.

Add To A Combobox A List Of Item (not Every Item) In A Txt Located On A Server
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)

Select A ComboBox Item Which Is A Drop Down List
i seem to have a problem when i try to select a ComboBox item which is a drop down list. The ComboBox contains a list of various items where the user can select from a list, the type of query he/she would like to perform on an Access Database. Two of the items in the Drop Down List are "Employee Sales Between Specified Weeks" and the other item is "Employee Sales Between Specified Months" (without quotation). Now in my VB code, i have a really long If/ElseIf Statement which includes all the options the user can select. Additionally, if the user has selected a week query, he/she must select a From Week, a To Week and a Year (for example week 3 to week 5 year 2009). From Week is another combobox (1-53 weeks) and To Week is also another ComboBox (1-53).When the user selects a month query, he/she should select a From Month from a ComboBox (1-12) and a To Month from another ComboBox (1-12) and the year from the same Combobox (e.g 2009).

Fill Combobox With List And Select Current Item?
I have 2 linked DB tables, Artists and Albums using ArtistID as the primary/foreign key.When I want to add a new Album, I have a new form open and I can fill a combobox with the list of Artists to choose from and edit all the details then save to the database.

However, when I want to edit the Album info, I can't seem to get the Artist associated with the Album, as well as all the rest of the Artists from that table, (in case I need to change the Artist associated with the Album).The information required comes from 2 linked tables, so that's where I'm getting lost.An example of this is when a person edits their profile on a webpage, for instance, a list of countries is usually listed in a combobox and the one selected is the country they selected when filling out the form previously, however, they still have the option to change it.

Program That Will Compare Array Of Grocery List Items Glist And Array Of Coupon Item List
I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

Convert A List(of Long) Into A String Array?
I want to convert a List (of Long) into a string array.

Reason: it's a list of database IDs and I want to make a comma delimited string to pass into a stored proc.I tried this:

Dim commaDelimitedList As String = String.Join(",", itemIDList.Cast(Of String)().ToArray)

but I'm clearly not using the Cast correctly since it throws an exception:

System.InvalidCastException: Unable to cast object of type 'System.Int64' to type 'System.String'..

Is there a way to get Cast working for this, or am I stuck with ConvertAll and a delegate function?

Drop Down Combobox, A List Of Options Are Available?
Is using Public Property the best way to achieve the following.From a drop down combobox, a list of options are available. Each option in the combobox has a number of public properties that need to be associated with it.When a option is selected, the user will then have two buttons that each call a differentsub, the appropriate options are passed to the sub.Each option will always have the same properties required to be passed.So I'm looking at something like this.

Public Class Parameters
Public Property server As String
Public Property replica As String
Public Propery path As String
End Class

Forms :: Drop-down List Combobox?
I have created a drop-down list box that holds 8 numbers representing a month span (3, 6, 9, 12, 15, 18, 21, 25 months). In order to prevent users from typing just anything into the text box above the combo box, I changed it to a drop-down listbox. The other requirement that I was hoping to implement was for the user to be able to type a number, after which the selection would jump to the appropriate item (i.e. the user types in '1', and the selection jumps to 12). This partially works. It will jump to 12, for example, but immediately after the user types the '1', the Selected Index event changes. The user cannot scroll down or up after typing in a number.

Populate A ComboBox From User List?
I want to populate a Combo Box with a list of names and from that have the contact information (address, phone, email, ect..) populate a series of textboxes. The list is roughly 20 names, but it could grow to a hundred or more. Since the contact information changes periodically, I would like a very easy way to maintain it (Excel or Access).

Update: I am just trying to understand whether I should use Linq (have to learn it) or is there some other way this should be done.

Bind Generic List Data To Combobox?
Please forgive, I'm new to Silverlight and am still trying to wrap my head around data binding...

I have a generic list obtained from a class using LINQ. The list has 4 objects, each object consisting of a Letter property (string - A, B, C and D) and a corresponding Number property (integer - 1, 2, 3, and 4).

In Silverlight, I have a combobox control and a text block. I'm trying to figure out how to:

Bind the combobox to the generic list so that the letters populate the combobox.When the user selects a letter in the combobox (say C), the corresponding integer value (3 for this example) is displayed in the text block.
