Hi there,

I have set up a childformdialog and want to have all the Add/EDIT-logic within the

childform. I call the childform with a param-object this way:

Dim aParam(1) As Object

aParam(0) = "N"    --->New record to add, the edit-button on the parentform would set an "E"

aParam(1) = "LIEFMAIN"    --> Name of the calling form

Childliefneu.ShowDialog(aParam)

In the childform I use the following code

Public Sub New(ByVal ParamArray aParam() As Object)

MyBase.new()

' Dieser Aufruf ist für den Designer erforderlich.

InitializeComponent()

' Fügen Sie Initialisierungen nach dem InitializeComponent()-Aufruf hinzu.

If aParam(0) = "N" Then

Me.lNeu = True

Me.Text = "Lieferanten aufnehmen"   -->"Add a supplier"

LieferBO1.Add()

Else

Me.lNeu = False

Me.Text = "Lieferanten bearbeiten"   --> "Edit a supplier"

LieferBO1.Edit()

End If

Me.cModule = aParam(1)

LieferBO1.Refresh()

Me.Refresh()

End Sub

When I call the childform to add a record, the form does not show an empty record which I expected to be added but the record the current row index points to and the controls are all disabled.

Is my approach wrong or did I miss something?

Thanks in advance

Thomas

Hi Ben,

thanks a lot for your explanation. That shoqs me clearly why some of my approaches

went wrong. I Will try this immediately.

Best regards

Thomas

Hi Ben,

I tried it and shifted the add edit code into an Overwritten onload-method

Protected Overrides Sub OnLoad(ByVal e As System.EventArgs)

MyBase.OnLoad(e)

If Me.lNeu Then

LieferBO1.Add()

Else

LieferBO1.Edit()

End If

LieferBO1.Refresh()

Me.Refresh()

End Sub

Now the follwing happens: If I start the form with a parameter for editing, the correct record is shown for editing. I can change values and save them, everything is fine.

When I choose to add a record. the form does not show, as I expected it, empty fiellds (controls like textboxes) for adding but behaves like I had choosen to add the actual record my grid is showing on the calling form.

Checking this with the debugger shows me, for example, that I enter the form with 79 records, the add-method of the BO is callled, after this I have 80 records, but the controls (text- and checkboxes and combos) aren't refreshed. 

What might I have done wrong?

Best regards

Thomas
