Problem with UserControl and BO

Rainer Kempf, RK — Mon, 09 Mar 2009 07:48:54 GMT

Hello,

I had a problem with a UserControl based on SFUserControl.

I use 3 Database. In the BO i set Datasourcekey always to the Databasename.

In my UserControl i dropped some BO to UserControl. All fine.

In Control no problems. I compile Control and Drop it on form.

Setup some Properties in Usercontrol on form and run form.

Form runs with no errors and COntrol works like it should.

Now i close Form.

When i next time load form in Designer i got errormessage.

[i]The DataSourceKey [ERPSYSTEM] is not defined.

Warning An error occurred while creating a new DataLayer for the business object.D:\Projekte.Net\StrataTestForm\StrataTestForm\Form2.Designer.vb

this is Code from Designerfile :

Me.Controls.Add(Me.MksBaseGrid1)

[/i]

MksBaseGrid1 is my Control. In this Control i had 1 BO where Datasourcekey ="ERPSYSTEM"

If i ignore the Error then Form will run with no errors but i am
not able to modify anything in designer for this form.

So what i wrong ??? I have really no idea

thanks for your help

Rainer

Hello Trent,

Found Problem

Problem was wrong Initialization-Order

I called a method in Load Container Event and Object was not completly instanciated

I moved my call to Container.New method and it works as expected.

Thanks for your help

This sound smore like an issue within the definition of your data sources. But without a sample, it is going to be very difficult for me to determine what you are fighting. If you could please post a simple sample reproducing your issue that would be helpful.
