Hi To All,

In my screen there is textbox with link button. when i click the link button another screen should open... Here is my source

 Case "lnkWNo"
                        Select Case pVal.EventType
                            Case SAPbouiCOM.BoEventTypes.et_ITEM_PRESSED
                                objXML.LoadForm("aaa.xml")
                                objForm = App.Forms.Item("AAA")
                                objForm.Mode = SAPbouiCOM.BoFormMode.fm_FIND_MODE
                                objForm.Items.Item("txtOrderNo").Enabled = True
                                objForm.Items.Item("txtOrderNo").Specific.value = Datasource.GetValue("U_worderno", Datasource.Offset).Trim
                                objForm.Items.Item("1").Click()
                        End Select

When i crossed this line

      objForm.Mode = SAPbouiCOM.BoFormMode.fm_FIND_MODE

error message as

object reference not set to an instance of object

same as when i crossed this line

       objForm.Items.Item("txtOrderNo").Specific.value = Datasource.GetValue("U_worderno", Datasource.Offset).Trim
             

error message comes as

object reference not set to an instance of object

Wats the problem.........

You need to initilise the form and linked button object also.

as

Dim oLink As SAPbouiCOM.LinkedButton

Set oColumn = oColumns.Add("A", it_LINKED_BUTTON)

Set oLink = oColumn.ExtendedObject

oLink.LinkedObject = lf_BusinessPartner

hope this will help you..

This particular link button is not in matrix.. its a master screen.
