That sounds like an older bug, are you sure you using the latest service release?

Installed NetAdvantage_Silverlight_20103.2159_SR

Is there any after that?

I am going to need a sample showing this behavior.

It is quite strange

It does not happen with the sample I have created but it does happen with my actual application

Anything that must be missing?

Both have same type of controls

I did a quick test

Any of my new application work well(Bugs are fixed)

But for old applications the Service release isnt getting applied

I had most of the places with code

 private void XamGrid1_CellExitedEditMode(object sender, Infragistics.Controls.Grids.CellExitedEditingEventArgs e)
        {
            e.Cell.Row.Cells["test"].Refresh();
            //XamGrid1.InvalidateData();
        }

The InvalidateData is used in older apps and the new app that I created today I dont need to give InvalidateData for any cell change

How to resolve this

Why isnt the service release getting applied for the existing apps?!

Little closer to the issue

I deleted the Reference that I had for the XamGrid

Removed the xamgrid from the page

Added a new one

It started giving error in the Styles file that

Error 6 Could not load file or assembly 'InfragisticsSL4.v10.3, Version=10.3.20103.2159, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb' or one of its dependencies. The system cannot find the file specified. C:\l\Assets\Brushes.xaml 1 1 Projename

That looks like the Brushes.xaml file is in a project that either A) does not have a reference to the required DLL or B) the xmlns declaration at the top has the version number in it and it can't find that particular version.
