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

Jun 17, 2011

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.

Get An Integer Value From A ComboBox Using A DataTable As Its DataSource

Jun 23, 2010

I am using code similar to this to populate a combobox with items from a database. The display works fine, but when I try to get the combobox.SelectedValue it is returning a DataRowView, where I need an integer. Obviously this is becuase I haven't casted the value to an integer, but the function, CInt(cboPosition.SelectedValue) is throwing an InvalidCastException. Is there any way that I can get the ValueMember's type to be an Integer?

Dim cn As New SqlConnection(CreditDisputesLogConn)
Dim cmd As New SqlCommand("CustomersLookup", cn)
Dim da As New SqlDataAdapter(cmd)

VS 2008 Why Doesn't The ComboBox Have A Selected Integer Property

Nov 26, 2009

Why can't you set the selected integer for the items in the combobox in the properties window instead of adding code in the form load event? I don't like to have to do things that way, I feel like it is less efficient. Should I just deal with their being no value property for combo boxes or is there a way to do it easier?

.net - Get An Integer Value From A List Box Populate With DataRowView?

Jan 6, 2010

Is there a way to get an integer value from a DataRowView? I have a list box with datasource set to a binding source. I would like to be able to do this:

dim num as integer
num = lstBox.SelectedValue

But I receive an InvalidCastException:

Conversion from type 'DataRowView' to type 'Integer' is not valid.

This is how I fill my list box:

myDataAdapter("SELECT CustID FROM Customers", cn)
myDataAdapter.Fill(myDataSet, "Customers")
myBindingSource.DataSource = myDataSet

[Code]....

I have one list box this works for and one it doesn't, so far. The only difference that I notice is: the one that works, the Query in the data apapter retrieves and auto number from my access table, the one that does not work, the Query in the data adapter retrieves a number.

Or, is there another way I should go about this?

The application that I am trying to make is a form with a list box for CustID, OrderID, ItemID, and others. The CustID is from table Customers, OrderID is from table Orders, and ItemID is from table Items.

Passing List Of (integer) To Select Statement?

Mar 27, 2012

I have a function that returns a Datatable. I am passing a list of Integer as an argument. Then I thought tis would work.

Public Function GetEventsByEventType(ByVal EventType As List(Of Integer), ByVal DayInterval As Integer) As DataTable
Using con As New MySqlConnection(strCon)

[Code]...

as you can see. I use string.join to convert the list of integer to something like this. '1,2,3'. Problem is that is read as a string so i get the incorrect results. I need to have where EventType IN(1,2,3).

VS 2008 Score Board, Having A Sorted List Sort On Integer?

Oct 5, 2010

I keep track of a score system for all users in a sorted list;

dim Scores as new sortedlist(of string, integer)

I can easely increse points for a cirtain person by;

scores("peter").value += 1

Now I need to display a top x list of the users, if users have the same score, it should sort alphabetically on the name. Of course it's also possible that users have the same score.I've already tried to make a new sorted list with as key the score, and added to that score the username. Later when displaying the scores, I've replaced the username with nothing. The only problem in this solution is that the numbers are sorted on asci value which has this order:

0
1
10
2
3
4

Also, if you make a sorted list like this:

dim Scores as new sortedlist(of integer, string)

You can't have two people with the same score... So, there must be something possible with the iComparer to sort on integers right?
