    ComboBox.Items.Clear()

    I am populating a ComboBox at run time. I insert the first value of
    "Choose Value"

    cboTaxValue.Ite m.Insert(0, "Choose Value")

    Then I loop through the rest of the values to be added to the combobox.

    My problem is that when I try to clear the ComboBox it clears the items
    that were inserted into the ComboBox, but does not clear the item I
    selected in the ComboBox... For Instance.

    The ComboBox has three choices: "Choose Value", ".023", ".546". I
    choose ".023" from the list. After I select it, I make the needed
    changes and press the update button. At the end of the UpdateButton
    Method, I have a line of code: cboTaxValue.Ite ms.Clear(). This line
    removes all of the items in the ComboBox except for the item I had
    previously selected. I have also tried cboTaxValue.Sel ectedText =
    String.Empty, that does not clear the item selected in the ComboBox
    either.

    Puzzled and confused I am.

    I hope this was enough explanation, appreciate any help.

      Use cboTaxValue.Tex t = String.Empty instead.

      Thanks,

          You can use

          cboTaxValue.Sel ectedIndex = -1
          or
          cboTaxValue.Sel ectedItem = Nothing

          to unselect a selected item.
