SBO Folders

Question

Hi
I' ve developed a form with multiple folders using Screen painter.  The lables, text boxes created each folders and set the "From Pane", "To Pane" as to relavant folders.  In those folders two of them are matrix folders. If we run preview on screen painter the fields are displaying properly in the relavant folders.
Then I' ve written the code for Combo box..etc.,  When I run the code, the particular form is displaying with folder without any fields in the folders.  If I open the form by using screen painter, and preview once then close the screen painter (without stop the program) then again i open the form from the menu, all the fields relavant to that folder is displaying properly.
Let me know, if anybody knows, how to overcome this problem and I would to like to say "Thanks in advance"
The code I've written as follows and I am using SBO 2005 B and dot net 2005.
Public Sub display()
        SetApplication()
         Dim oColumns As SAPbouiCOM.Columns       
         Dim oItem As SAPbouiCOM.Item
        Try
            LoadFromXML("MachineMaster.srf")
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try
        Try
            Oform = SBO_Application.Forms.Item("frmachine")
            ' Add Edit Items
            oItem = Oform.Items.Item("txtmcode")
            txtmcode = oItem.Specific
            oItem = Oform.Items.Item("txtmname")
            txtmname = oItem.Specific
            oItem = Oform.Items.Item("txtgname")
            txtgname = oItem.Specific
            AddMgrpcombo(txtgname)
            oItem = Oform.Items.Item("txtwcr")
            txtwcr = oItem.Specific
            AddWCntcombo(txtwcr)
            oItem = Oform.Items.Item("txtpdate")
            txtpdate = oItem.Specific
            oItem = Oform.Items.Item("txtidate")
            txtidate = oItem.Specific
            oItem = Oform.Items.Item("txtmdn")
            txtmdn = oItem.Specific
            oItem = Oform.Items.Item("txtnmdt")
            txtnmdt = oItem.Specific
            oItem = Oform.Items.Item("txtmhr")
            txtmhr = oItem.Specific
            oItem = Oform.Items.Item("txtmst")
            txtmst = oItem.Specific
            oItem = Oform.Items.Item("txttsp")
            txttsp = oItem.Specific
            oItem = Oform.Items.Item("txtremark")
            txtremark = oItem.Specific
            oItem = Oform.Items.Item("txtaccode")
            txtaccode = oItem.Specific
            AddAccodecombo(txtaccode)
            oItem = Oform.Items.Item("txtacname")
            txtacname = oItem.Specific
            ' Add a matrix for shift
            oItem = Oform.Items.Item("mat1")
            Omatrix = oItem.Specific
            oColumns = Omatrix.Columns
            ' Shift Code
            colscode = oColumns.Item("colscode")
            colsname = oColumns.Item("colsname")
            Omatrix.AddRow()
            AddsftToCombo(colscode)
            ' Add a matrix for item
            oItem = Oform.Items.Item("mat")
            Omatrix = oItem.Specific
            oColumns = Omatrix.Columns
            ' item Code
            colicode = oColumns.Item("colicode")
            coliname = oColumns.Item("coliname")
            colqty = oColumns.Item("colqty")
            coluom = oColumns.Item("coluom")
            Omatrix.AddRow()
            AddItemsToCombo(colicode)
            SetToolBarEnabled()
            Oform.DataBrowser.BrowseBy = "txtmcode"
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try
    End Sub
Thanks and Regards,

Hi Venkatesan,
I remember having had a similar problem a while ago ("folders" showing properly in the ScreenPainter, but not in the application).
If I recall correctly, it's a matter of binding the tabs properly to a DataSource.
As the SDK help mentions:
To hold data within a Folder item, the item must be bound to
a data source (UserDataSource or DBDataSource) using Folder.DataBind.
You will also have to set the Folder#ValOn and Folder#ValOff (though I'm not sure whether the latter is absolutely necessary) properties properly. The values of the "ValOn" property should be different for each folder. Setting the value of the DataSource the "folder" is bound to to one of these values should select the proper "folder".
Yours,
Olivier
