Here is my problem (VB.net). I have a form and I want to load the data during the form load event. I initially I built the code into a button, so the form loaded, I clicked the button and then my combobox had all the data. Now I want that code to run without having to push a button. So I moved the code into the Load and nothing happened, not even an error. I created a sub and called it from the load, nothing happened. I put the code back into a button then it worked. When all else fails, read the help...so I did. It shows a walkthrough of loading data to a datagrid BUT FROM A BUTTON also. At the bottom it say:
*  Make the grid display data without being explicitly loaded by the user. To do this, you add a Fill method to the form's New method (in Visual Basic) or constructor (in C#) and remove the Load button
Does it show you how? No. So I think I need to add a fill method to the form's New Method? Can somebody help me?
I don't see the New method in the IDE.


Below is the code I'm currently using in the button:

Thanks
   Private Sub LoadLookUps()
        'Create a Connection
        Dim oConn As System.Data.OleDb.OleDbConnection
        Dim oCommand As New OleDbCommand()

        oCommand.CommandText = "ct_lu_AuthorizedDeptsByUsers"
        oCommand.CommandType = CommandType.StoredProcedure

        'Create a new parameter and add it to the parameters collection
        Dim oParam1 As New OleDbParameter("@tiUserID", OleDb.OleDbType.Integer)
        oParam1.Value = gnUserID
        oCommand.Parameters.Add(oParam1)
        'Connect to Database
        oConn = SqlConnect(gcConnString)
        oCommand.Connection = oConn
        Dim goView As New Data.DataView()
        'Load the DataView
        goView = VFPToolkit.vfpData.SqlExecute(oConn, oCommand, "Departments")
        If VFPToolkit.files.File("C:\dev.cqi") Then
            VFPToolkit.vfpData.Browse(goView)
        End If
        Me.ComboBox1.DataSource = goView
        Me.ComboBox1.DisplayMember = "deptdesc"
        Me.ComboBox1.ValueMember = "deptid"
   End Sub
