UPDATE TO MY INITIAL MESSAGE: I think (maybe) the reason dsChanges gets NULL value is that there are no changes in the dataset. I wrote a few lines of code checking the .current and .original values for all columns in the row where I made the change but the values are the same. I must be doing something wrong in the way I bind the textboxes. Here is my code of binding the testbox to the typed dataset:
this.txtTextBoxName.DataBindings.Add("Text", bindingSource1, "ColumnName");
The values from the dataset/datatable do appear in the text boxes. But could it be that the changes do not get updated back to the dataset?
