Hello,

Binding the Value-Property of a NumericUpDown-Control (using DataBindings):

Dim bndNBRtechniciansForService As Binding = New Binding("Value", Me.dvInstallations, "NBRtechniciansForService")
AddHandler bndNBRtechniciansForService.Format, AddressOf NullToIud
AddHandler bndNBRtechniciansForService.Parse, AddressOf IudToDB
Me.iudNBRtechniciansForService.DataBindings.Add(bndNBRtechniciansForService)
produces the following exception:
An unhandled exception of type 'System.Exception' occurred in system.windows.forms.dll
Additional information: DataBinding could not find a row in the list that is suitable for all bindings
This occurs only if you close (dispose) the form (instance 1) and re-open it (new instance 2) AND you didn't activate the tab (on instance 1) containing the NUD-Control.

If you just click the tab containing that control before you close the form and then re-open a new instance of the form, there is not problem at all.

I think it has something to do with the TabPageControl re-binding but can't seem to find any input on that.

The controls are bound to a DataView
I use vb.NET 2003 ent. arch
XP SP1a

Any suggestions (like a work-arround) wuold be very nice,


Michael
 
Hi Michael,

There seems to be some features when binding checkboxes, controls on
tabpages...
Did you try removing all bindings and events manually in OnClosing method?
Also, you might read this thread:

Hi Miha,

I forced the BindingContext of the TabControl as suggested (before creating
the Bindings)

tabPage.BindingContext = Me.BindingContext

This "seems" to be a workaround for me.

Thanks alot,

Michael
