can i assign values to combo box drop down list?
hello all!
i would like to ask u if i could assign values to my combo box' items.
i have a combo box with 2 different options. In my programm i have to pass as a parameter an integer, depending on the choice of the user. so if the user chooses "distance" the integer i pass is 1 and if he chooses "time" the integer value i pass as argument is 2. I would like to know if i can somehow bind each choice with a number (distance-1,time-2) so as to avoid the checks with if clause. this is how my programm looks like now:
Dim mode As Integer
If (cmbMode.SelectedIndex.Equals(-1)) Then
MessageBox.Show("You must select type first!")
Exit Sub
Else
If (Me.cmbMode.Text.Equals("Distance")) Then
mode = 1
ElseIf (Me.cmbMode.Text.Equals("Time")) Then
mode = 2
End If
End If
Any help appreciated!!:)

# 1 Re: can i assign values to combo box drop down list?
You can create an Enum to contain the values and their descriptions:
Public Enum Modes
Distance = 1
Time = 2
End Enum
Bind the Enum to the ComboBox:
Private Sub MyForm_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
cmbMode.DataSource = System.Enum.GetValues(GetType(Modes))
End Sub
Then simply read the ComboBox's SelectedValue into an Integer variable:
Dim Mode As Integer = CInt(cmbMode.SelectedValue)

But, doesn't this still require an If statement to find out what the current value of Mode is?

In the original question, he said that he's passing the value of Mode as a parameter to another function. There's probably an If statement in that function, but that's not our problem. ;-)
