    Hi,

     

    is this possible?

    I created a class with 

    class SpreadController 

     private WithEvents m_fp as Fpspread

    end class

     but this does not work?

    Any hint?

    Hello,

    Using the Latest build of Spread for Windows Forms, I did the same and I am able to see all the Events related to FpSpread listed in m_fp. Please have a look,

       Public Class Form1
           Private WithEvents m_fp As FarPoint.Win.Spread.FpSpread
           Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
             m_fp = New FarPoint.Win.Spread.FpSpread
             m_fp.Sheets.Count = 1
             m_fp.Sheets(0).RowCount = 10
             m_fp.Sheets(0).ColumnCount = 10
             Controls.Add(m_fp)      
          End Sub
          Private Sub m_fp_CellClick(ByVal sender As Object, ByVal e As FarPoint.Win.Spread.CellClickEventArgs) Handles m_fp.CellClick
            MsgBox("hello")
          End Sub
       End Class

    If this doesn't help you, please let us know your requirements in detail.

    Thanks,

    Well, in my actual form (let's say myForm) I created a Spread fpMySpread with the Spread Designer.

    But I don't  want to handle the Events coming from fpMySpread in this form.

    Therefore I deceided to create a separate class:

    Class MySpreadController 

           private WithEvents m_fp as FpSpread

           Sub New(fp as FpSpread)

                 me. m_fp = fp

           end sub

    end class

    In myForm I want to create an instance of the mySpreadController by

    m_myController = new (mySpread)

    Sub MyForm_Load(....)

            m_myController = new (mySpread)

    end sub

     ...and I hoped that the events arrived in MySpreadController - but they did not arrive.

    Any hint

    Hello,

    When I created a Class named MySpreadController

    Public Class MySpreadController
        Private WithEvents m_fp As FarPoint.Win.Spread.FpSpread
        Sub New(ByVal fp As FarPoint.Win.Spread.FpSpread)
            Me.m_fp = fp
        End Sub
    End Class

    I see that the Spread's Events show up in MySpreadController with m_fp.

    Could you please send across a zipped application for us to debug.

     

    Thanks,

    Hello,


    If you create a class that Inherits from the FarPoint.Win.Spread.FpSpread, then you can catch the events in that class. Take a look at the following thread for code snipet to implement this.
