VSTO Excel, Save Combo Box Text, ComboBoxes Reset Upon Workbook Opening?

I have several ComboBoxes in an Excel VSTO Solution. The combos are windows forms combos.

The issue is that I'd like selected value in the 开发者_如何学编程combo to be repopulated when the user reopens the spreadsheet. Currently, I know that the values are saved with the spreadsheet, I know this I've ran into ClickOnce installer problems due to developing and testing on the same machine, and I can see the spreadsheet open, and the installer go to get the new version. During that time, I see the combo values I want.

However, once the customization installs and the spreadsheet initializes, the combos reset to default text values. I can think of a few ways to get around this, involving using cached data... Does anyone know if there is a simple way to keep the combos from resetting when the spreadsheet opens?

I don't know if this is necessarily the best solution, but this is what I ended up doing.

I first embedded my combos into cells.

Friend WithEvents cmbType

Private Sub EmbedCombo()
   cmbType = Me.Controls.AddComboBox(Me.Range("A7"), "cmbType")
End Sub

Then I created a sub to write the value of the Combo Text, back into the cell that the control resided in.

Private Sub SaveComboText()
   Me.Range("A7").Value = Me.cmbType.Text
End Sub

Finally a routine that writes the Cell Value back to the Combo.

Private Sub LoadComboText()
   Me.cmbType.Text = Me.Range("A7").Value  
End Sub

To make it all work, I use the WorkBoook BeforeSave Event, and the WorkSheet.StartUp Event.

First

Private Sub ThisWorkbook_BeforeSave() Handles Me.BeforeSave
    Globals.Sheet1.StoreComboValues()
End Sub

Then

Private Sub Sheet1_Startup() Handles Me.Startup
  Call LoadComboText()
End Sub

If someone else knows of a better way to avoid this, let me know:)
