Hello

Your log is nothing conclusive:

What is this? IWWebGrid? TTIWCustomWebGrid? tmsiwUXlsSheet?

Sorry.

It is IWCGJQGrid. I dont have IWGrid or TMS in the project

Hi

Well i don't know how is this possible,

but you should define JQGridDataSetProvider.KeyFields or set Col.Key to a unique key field name(s).

[zsleo]

My fault! (again)

I missed JQGridDataSetProvider.KeyFields for one grid
(Again)...
