Passing BO to childform and use it with a BBS and a Datagridview

Thomas Holste — Mon, 06 Apr 2015 10:25:32 GMT

Hi there,

in a procedure I fill a BO with data and pass it to a form the procedure is calling. On the form is a datagridview and a BusinessBindingSource. I gave linked an "empty" BO to the BBS to design the grid. Now when the form is loaded, I want to replace this BO with the BO passed to the form in the new-Event.

[code]

Private myvormerker As MyvormerkerBO

Public Sub New(ByRef myvm As MyvormerkerBO)

MyBase.new()

InitializeComponent()

myvormerker = myvm

End Sub

[/code]

In the load-event I try

[code]

Me.VMGrid.DataSource = Nothing

Me.BBS1.BusinessObject = myvormerker

Me.VMGrid.DataSource = Me.BBS1

[/code]

At first I thought it to be working as the data is correctly displayed but the grid is some kinf of idabled as I cannot mark any cell or move to another row or do anything with it.

Could someone tell me what I am missing?

Thanks in advance

Thomas

Hi Thomas,

I am glad you fix the issue, even when you had to re-create your form.

Hi Edhy,

thanks for your help but after using it, I avoid using the childform-control because it is only suitable for easy tasks, as someone told me in another thread. I have replaced it almost everywhere in my app as I had only problems with it ( a lot of threads in this forum tell about it)

But I have solved the problem. After looking and looking at it, I deleted it all and rebuild it exactly the same way and now it works as expected.

Strange world of Visual Studio.

Best regards

Thomas

Hi Thomas,

You have to use a Child Form Dialog control to call your other form. The ChildformDialog have a business object translator which allows you to pass the BO from the calling form to the child form dialog.

Take a look at the SF help under the Application Framework->UI Layer->Child Form Dialog
