Data entry using matrix object

Question

HI,
I am new to SAP B1 and its SDK. I got struck while trying with the Turotial provided with SDK Help center - Blanket Agreement. Following are the problems.
1) The Status combo box is not having values
2) The values I entered into the Matrix columns are vanished when I navigated to next field(Combo box/Edit Text).
Please Help!
Thanks,
Ajith G.

Hi Ajith,
You should look in the example code under the subs : AddDataSource and BindDataSource
For every items in SBO, you should create the user data source and Bind it to your item
If you fail to bind it, or error were raised when binding it, your input value will be lost.
Example for an EditText created . Unique ID for this item is "txtExample"
You have to
'Declare  an user data source in global
    Private oUDS As SAPbouiCOM.UserDataSource
'And then you add the data source to your form.
Private Sub AddDataSource(ByVal FormUID As String)
      oform = sbo_Application.forms.item(FormUID)
      oUDS = oform.datasources.userdatasources.Add("txtEx", SAPbouiCOM.BoDataType.dt_SHORT_TEXT)
End SUb
'Bind The Datasource to your Item
Private Sub BindDataSource(ByVal FormUID As String)
    Dim oForm as sapbouicom.form
    Dim oEdit as sapbouicom.EditText
    oForm = sbo_application.forms.item(formUID)
    oEdit = oform.items.item("txtExample").specific
    oEdit.databind.SetBound(True,"","txtEx")
End Sub
Hope it helps
Regards
