Bound ListBox Values

[SenileOwl]

I posted this in the Visual Basic Forum, but I've been wondering if .NET might be a better place for it. I'm working in Visual Basic Microsoft Visual Studio .NET 2005.

I'm very new to the whole programming thing and I'm having a little trouble with the syntax of my code.

My code contains a bound listbox where the display member and value member are two different values. I want my program to cycle through the listbox and compare the value member of each item in the list box with a fixed value. My problem is I can't seem to find the syntax to grab the value of the item in the list box. I can't use DescriptionList Box.SelectedVal ue. Because the item is not selected. This is an example of some code I've tried, but it is not working.

For counting As Integer = 0 To DescriptionList Box.Items.Count - 1

If DescriptionList Box.Items.Item( counting).value = Me.DataSet.Tabl e.Rows(i).Item( 1) then


DescriptionList Box.SetSelected (counting, True)

end if
Next

I guess my question is what can I use in place of ListBox.Selecte dValue, to capture the Value of a bound listbox's item that is not selected?

Just use the Items property. DescriptionList Box.Items(1) gives you the second item in the list. You can also use a for each loop. HTH --Sam

 Dim s As String
 For Each s In DescriptionListBox.Items
     MessageBox.Show(s)
 Next s

No such luck. My ListBox is bound to a table. Therefore the program reads items as a system.data.dat arowview. If I try and put a .ToString on it or in someway convert it to a string, the program gives me "System.Data.Da taRowView" as my listbox item.

Ah, I'm more senile than you. Not exactly sure how to do it in VB, but in C#, it is

DataRowView dr = (DataRowView)DescriptionListBox.Items[0];
String valueColumn = DescriptionListBox.ValueMember;
MessageBox.Show(dr[valueColumn].ToString());
 

Hopefully, that will get you started. --Sam

You are amazing. It worked. Here is the code I used for VB

Dim anewtry As DataRowView
anewtry = DescriptionListBox.Items(counting)
Dim blahblah As String
blahblah = DescriptionListBox.ValueMember
MsgBox(anewtry(blahblah))
 

Thanks a ton.
