Hi,
Yes. If you had several controls bound to a dataset the curencymanager would keep them in sync. Since you are on a different form it considers the dataset to be a differnet datasource.

Hi guys,
I'm new to .net & i've got a problem with regards to datasets & data binding. Here goes, I've got a data grid & the active row (position) is the 3 row. Now, i take this data set, & pass it to a seperate form, where i want to be able to edit the details of this row. So, in the load event of this new form, i bind the necessary columns of the table to the required controls. Problem - The data displayed is that of the first row!!!!! is this a behaviour of .Net, where when data is bound to a control, the data will always be displayed from the very first Row, in other words.... is the current row in the datagrid totally independant of the dataset (source), & has no effect on this?? -- Besty Regards, TJ
What i would also like to know is the following,
1. Now in form one, i have set the position for the dataset. 2. Next i pass this data set as a parameter to another form. 3. in this new form i set bind this dataset to other controls. 4. The position of the data in this second form is NOT the same as that in (1). Question? Is this a behaviour of .NET? Thanx for the solution Ken.
