managing ConcurrencyException

Hi,

I try to manage ConcurrencyException with my own SoftCollision form (wich is nearly a SF SoftCollision form, only localized).

this form is shown from my maintenance form:
[code]

Private Sub V_TVA_ConcurrencyException(ByVal e As MicroFour.StrataFrame.Data.ConcurrencyExceptionEventArgs) Handles V_TVA.ConcurrencyException

Dim loFrmConflit As New MLControlesSF.MLSF_SoftCollisionDialog(e)
If loFrmConflit.ShowDialog(Me.MdiParent) = Windows.Forms.DialogResult.OK Then
...

[/code]

After closing that loFrmConflit, your SF SoftCollision form is raised! why? :crazy:

You definitely should not feel that way at all! The framework has a lot of functionality and is very deep...so it is easy to miss a property here orr there! We have all done it!!! ;)

Ben,

I had found all that I needed in the helpfile and on that forum (thanks to all contributors), about this event. And yes, all I want is in the event args, and I manage it with my users requirements.

Glad you found that. When you turn that option off, you'll want to handle the CurrencyException event on the business object or form and all of the information you'll need you'll find in the event args: option to resave the record, the primary key of the row, a list of the columns that don't line up, etc.

Trent,

thanks, thanks a lot!

I've spent hours and hours reading all topics on forums about concurrency exception, reading helpfile, reading your source code... and I have not seen that little property :pinch:

so thanks again!

You just need to set the AutoHandleCollisions property on the form to False and then only yours will appear.
