i have 3 combo boxes in my form. During form load, i load the combo box, code as below:-

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load

Load_PartGroup()
Load_StockCategory()
Load_Customer()

NewMode = True

Clear_Fields()

End Sub

Private Sub Clear_Fields()

ComboBox1.SelectedIndex = -1
cboCustomer.SelectedIndex = -1
cboCategory.SelectedIndex = -1

End If

what i want is, when the form load, load the combo box & set the combo box where selectedIndex=-1, so that the combo box can displayed blank combo box for me.

thank you.

So what is the issue? ComboBox1.SelectedIndex = -1 will show the blank combobox, right? Or you want something else then explain.... rolleyes.gif

And Please use Code Tags while posting code.

Yes, you are correct. it is displayed blank combo box. the ComboBox1.SelectedIndex = -1 does not work if i put the code in form load. what i guess is because of my load function Load_PartGroup() which load data into the combobox1.....

at this moment, when my form is load, then all combo box displayed the default value. i want it show blank like (.SelectedIndex = -1) ......

thx

Are you binding the data directly from database to combobox? If you can post the code of Load_PartGroup() function, there will be more clarity.

this is the code:-

Private Sub Load_PartGroup()

daPG = New SqlDataAdapter("Select * From nPartGroup Where Active = " & 1 & " ", sConn)
dsPG = New DataSet
daPG.Fill(dsPG, "nPartGroup")

With ComboBox1
.DataSource = dsPG.Tables(0)
.ValueMember = "PGID"
.DisplayMember = "PGName"
End With

End Sub
