Syntax

'Declaration
Public Sub SubmitChanges
'Usage
Dim instance As DataContext

instance.SubmitChanges()

public void SubmitChanges()

Exceptions

Exception	Condition
InvalidOperationException	ObjectTrackingEnabled is false - or - At least one conflict in ChangeConflicts from the last time SubmitChanges() was called is not yet resolved.
ChangeConflictException	There is a concurrency conflict.

Remarks

This overload of SubmitChanges() will use FailOnFirstConflict as the failure mode. To persist changes with a different mode, use SubmitChanges(ConflictMode) or SubmitChanges(ConflictMode, Boolean),

The version of changed list items will be incremented. To persist changes without incrementing versions, use SubmitChanges(ConflictMode, Boolean).

Examples

The following example shows this overload of SubmitChanges() being used:

foreach (TeamMember teamMember in teamSite.TeamMembers)
{
    teamMember.TopTask = “Fiscal Planning”;
}

try 
{
    teamSite.SubmitChanges();
}
catch (ChangeConflictException e) 
{
    teamSite.ChangeConflicts.ResolveAll();
    teamSite.SubmitChanges();
}

For Each teamMember As TeamMember In teamSite.TeamMembers
    teamMember.TopTask = "Fiscal Planning"
Next teamMember

Try
    teamSite. SubmitChanges()
Catch e As ChangeConflictException
    teamSite.ChangeConflicts.ResolveAll()
    teamSite. SubmitChanges()
End Try
