CheckedItems, which are set in code, aren't displayed in sfComboBox

[Helmut]

 Hello,

I can determine and set the CheckedItems in the code.

However, they are not displayed in the control

Here my code:

Public Sub Stand_WG_Einstellen(cb As Syncfusion.WinForms.ListView.SfComboBox, byVal lID_Stand As Int32)

            Dim cSql As String, cMsg As String

            cSql = "Select ID, ID_Warengruppe from tblTemp_Stand_WG_Ware Where ID_Stand = " & lID_Stand

            Dim adoConn As New OleDbConnection(gcProviderACEOLEDB120 & gcDataPath & "\MC_UP\Mand" &          gcGewMandant & "\MCO_UP.accdb")

            Dim mC As New OleDbCommand(cSql, adoConn)

            Dim mDR As OleDbDataReader

            cb.CheckedItems.Clear()

            Try

                adoConn.Open()

                mDR = mC.ExecuteReader()

                While mDR.Read()

                    If Not IsDBNull(mDR("ID_Warengruppe")) Then

                        For Each oRow As Object In cb.DropDownListView.View.Items.ToList()

                            If oRow("ID") = Convert.ToInt32(mDR("ID_Warengruppe")) Then

                               cb.CheckedItems.Add(oRow("Warengruppe"))

                            End If

                        Next oRow

                    End If

                End While

            Catch err As Exception

                Beep()

                cMsg = "Setting "

                MsgBox(err.Message, MsgBoxStyle.Critical, cMsg)

            End Try

'Only for test #########################################################

            MsgBox(cb.CheckedItems.Count)

            Dim i As Integer

            For i = 0 To cb.CheckedItems.Count-1

                MsgBox(cb.CheckedItems(i).ToString)

            Next

'###################################################################

            adoConn.Close()

            adoConn = Nothing

            OleDbConnection.ReleaseObjectPool()

        End Sub

I need help. What do I wrong?
Regards
Helmut

Hello Gokul,

many thanks for your help in your sample.

My mistake was:

For Each oRow As Object In cb.DropDownListView.View.Items.ToList()

If oRow("ID") = Convert.ToInt32(mDR("ID_Warengruppe")) Then

       cb.CheckedItems.Add(oRow("Warengruppe"))
  End If

next oRow

I changed it to:

 For Each oRow As Object In cb.DropDownListView.View.Items.ToList()

 If oRow("ID") = Convert.ToInt32(mDR("ID_Warengruppe")) Then

                  cb.CheckedItems.Add(oRow)

  End If

next oRow

Now, all works fine!

Thank You and regards

Helmut
