We are using a alternative method for updates. Instead of using primary key we update the Dom element and then the respective JSON data.
var text = this.gridIDMap.cellAt( cell.index, cell.rowIndex ) text.innerHTML = d; //update jason var data = this.gridIDMap.dataSourceObject(); data[cell.rowIndex][cell.columnKey] = d
If I then double click on this changed data in the grid cell the old value appears as this was only a copy of the data. To fix that I must do a dataBind() to get my new copy data bound. Unfortunately this dataBind is very slow on our grids? So I was hoping to find a way to update the local directly DATA instead.

No resolution just found the cause. Its a compound question if you see the other links. I believe this issue and
http://ko.infragistics.com/community/forums/p/86479/431759.aspx#431759
are related. The problem here is that any time I make a selection that includes a primary key column and change the data, all the cells data become blank for consecutive edits.
This problem is very difficult to give an example as I have a way to select multiple cells and would take a lot to replicate that. So I'm thinking it may be best to see that other bug first and hope this is fixed in the process.
The other link I provided was a fix for the issue of use infragistics without a primary hey. Long story short, our data is not connects to a database. We just display data on a screen. So the request to make infragistics work without the need of a primary key was brought up. A solution was presented but I'm afraid its buggy. Though this is just a guess...
Hi Sean,
Per your most recent post it appears that you have a resolution that will work for you. Let me know if that is not the situation or if you need further assistance.
Ok, the above method does work but there is one very strange thing going on here.Depending on my selections, once the data has been updated my next attempt to edit a cell returns "TypeError: rec is null" on line 35 on datasource.js". seems to be dependent on the data in the grid. Very small grid has no problems, data is update each time just fine. Large grids have the issue but its not always the same kind of selection. Most selection work just fine yet sections that include the last column seem to give this error. In all case the _data is correct after my first edit but I get that type error on any sequential edit in many cases.
{ edit }
I think I know the issue. If the primary key is in the selection it fails.

Per this fix I should be able to use the infragistics code without the primary key.
Duplicate post.
