I am going to make a couple of quick changes to other areas in my application, run some tests, then post the update. Looks like I am back in business!

Instead of getting in contact with DevExpress, etc. we went ahead and made a code change in the event that another 3rd party control references an IBindingList implementation during disposal. Ultimately this is a simple fix, but the reason for all of the confusion was due to different versions of a 3rd party control acting different ways. The next minor release posted will include this fix, but you can go ahead and change the source if you like temporarily. You WILL NOT have to maintain this source as it has already been changed. But the issue is that the _BusinessObject has already been disposed, thus when the grid implicitly attempts to dispose of the data source, an error occurs. Here is the code as it should be to resolve the error: BusinessBindingSource, RemoveBOHandlers() ''' ''' Removes the necessary event handlers from the business object. ''' ''' Private Sub RemoveBOHandlers() '-- Make sure that the BO has a reference If _BusinessObject Is Nothing Then Return Try '-- Remove the necessary handlers RemoveHandler Me._BusinessObject.AfterAddNew, AddressOf BusinessObject_InternalAfterAddNew RemoveHandler Me._BusinessObject.BeforeAddNew, AddressOf BusinessObject_InternalBeforeAddNew RemoveHandler Me._BusinessObject.InternalAfterAddNew, AddressOf BusinessObject_InternalAfterAddNew RemoveHandler Me._BusinessObject.CurrentDataTableRefilled, AddressOf BusinessObject_CurrentDataTableRefilled RemoveHandler Me._BusinessObject.CurrentView.ListChanged, AddressOf BusinessObject_CurrentView_ListChanged RemoveHandler Me._BusinessObject.Navigated, AddressOf BusinessObject_Navigated RemoveHandler Me._BusinessObject.IsDirtyChanged, AddressOf BusinessObject_IsDirtyChanged Catch ex As Exception End Try End Sub

Group: StrataFrame Users Posts: 223, Visits: 893	Hi SF Team, I understand where to make the change but I am running VS 2005 and the Microfour Strataframe.sln is not loading. I have loaded the Microfour Strataframe Inherited IU project and updated the DevExpress references to v9.1.5 and created the new DLL successfully. I tried loading the Microfour Strataframe Business project, but I get over 100 errors. I am not sure what to do now. What are the steps I need to take to implement this fix or will you post a new dll with this fix? Thanks, Jeff

Group: StrataFrame Developers Posts: 6.6K, Visits: 6.9K	Sorry for the delayed responses. We have not been in the office the last several days for personal reasons. At any rate, I am doing a new build - 1.7.0.1. This will include these changes for you. I will post it in the My Account area as soon as it is ready.

Group: Forum Members Posts: 153, Visits: 462	Trent, I am also getting this same error on a form that has worked until the upgrade to 1.7.0. There are no third party controls on this form. Just StrataFrame and Grids. One of them has a BBS. Is there a quick fix for this? or do I need to download 1.7.0.1? The error: Source : mscorlib Stack Trace: at System.ThrowHelper.ThrowKeyNotFoundException() at System.Collections.Generic.Dictionary`2.get_Item(TKey key) at MicroFour.StrataFrame.Business.BusinessLayer.get__CurrentDataTable(Boolean IsSharedTable) at MicroFour.StrataFrame.Business.BusinessBindingSource.RemoveBOHandlers() at MicroFour.StrataFrame.Business.BusinessBindingSource.Dispose(Boolean disposing) at System.ComponentModel.Component.Dispose() at System.ComponentModel.Container.Dispose(Boolean disposing) at System.ComponentModel.Container.Dispose() at TrustedVALET.forms.order.frmOrder.Dispose(Boolean disposing) in C:\TrustedVALET\TrustedVALET\forms\order\frmOrder.Designer.cs:line 12 at System.Windows.Forms.Form.WmClose(Message& m) at System.Windows.Forms.Form.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativewindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativewindow.WndProc(Message& m) at System.Windows.Forms.Nativewindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) The error is not very helpful as you can see the 2^nd line in the stack trace is: at System.Collections.Generic.Dictionary`2.get_Item(TKey key)

Group: StrataFrame Developers Posts: 6.6K, Visits: 6.9K	Ross, I am assuming that you are using DevExpress grids or something along those lines. Yes, please download the 1.7.0.1 build as we made a change to prevent any 3rd party control that references the IBindingList interface during or after disposal.
