DataAdapter.Update Fails on child table

I have a GGC with parent/child relationship. The DataAdapter.Update for the parent works fine, but the Child does not update, it always returns 0 for the update count. Thx.

Hi this.sqlDataAdapter1.Fill(dataSet11,"Parent"); this.sqlDataAdapter2.Fill(dataSet11,"Child"); The above code is used to fill the dataset using the Parent and Child tables. this.sqlDataAdapter1.Update(dataSet11); this.sqlDataAdapter2.Update(dataSet11); These codes are used to update the parent and child tables respectively. I guess that you might have missed to update the child table using its own DataAdapter as I mentioned above. Please send me a sample with the issue if this doesn''t serve your purpose. Best Regards Mouli.
