Introduction:
In SAP Business One, combo boxes offer a convenient way to select predefined values within the user interface. Today, we'll delve into the SAP Business One Software Development Kit (SDK) to understand how to populate and fill a combo box dynamically.
Requirements:
SAP Business One SDK installed and configured.
Familiarity with C# or VB.NET programming languages.
Step-by-Step Guide:
1. Connect to SAP B1 Company Database
Ensure that your SDK environment is set up and correctly connected to the SAP B1 company database.
2. Access the Combo Box Object
Retrieve the combo box object you want to populate with values. Identify the specific combo box control by its unique ID or name.
3. Define Values to Populate
Prepare the values you wish to fill into the combo box. These can be retrieved from a database, predefined list, or generated dynamically.
4. Populate Combo Box with Values
Public Sub FillComboBoxValue(ByVal oApp As Object, ByVal aForm As SAPbouiCOM.Form, ByVal aComUId As Object, ByVal strQuery As String, ByVal blnDefNew As Boolean)
'********************************************
'' DECLARE LOCAL VARIABLES'
'********************************************
Dim aCombo As SAPbouiCOM.ComboBox = Nothing
Dim oRS As SAPbobsCOM.Recordset = Nothing
'********************************************
oApp = New ClsSAPConn
'********************************************
oRS = oApp.SAPCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset)
aCombo = aForm.Items.Item(aComUId).Specific
'******************************************
Try
oRS.DoQuery(strQuery)
'' To Avoid Valid Value Issue
If aCombo.ValidValues.Count > 0 Then
For i As Integer = 1 To aCombo.ValidValues.Count
aCombo.ValidValues.Remove(0, SAPbouiCOM.BoSearchKey.psk_Index)
Next
End If
If oRS.RecordCount > 0 Then
While Not oRS.EoF
aCombo.ValidValues.Add(oRS.Fields.Item(0).Value, oRS.Fields.Item(1).Value)
oRS.MoveNext()
End While
End If
Select Case blnDefNew
Case True
aCombo.ValidValues.Add("-9", "DEFINE NEW")
Case False
aCombo.ValidValues.Add("", "")
End Select
aCombo.Item.DisplayDesc = True
Catch ex As Exception
Finally
If aCombo IsNot Nothing Then
aCombo = Nothing
End If
If oApp IsNot Nothing Then
oApp = Nothing
End If
End Try
