I bind my datagridview to a dataset returned from a web service:

ds = WS.testReport(param1, param2)
ReportGrid.DataSource = ds.Tables(0)

The data displays fine.
Now, what I want to do is to hide all rows that match some specific
criteria (every row whose column has a value of 1).
So I try: ReportGrid.Rows(i).Visible = False

At row 0 (and only for that row) I get this error:
"Row associated with the currency manager's position cannot be made
invisible."

I have searched everywhere for a hint to cope with this error and
haven't found anything. How can I access this manager's properties?
Any help will be greatly appreciated.

You should bind the grid to a DataView instead. Like:
[...]
DataView dv = new DataView(ds.Tables[0], "visible = 1", null,
DataViewRowState.CurrentRows);

ReportGrid.DataSource = dv;
[...]

The second parameter to the constructor is the RowFilter.

/B :)

Thank you very much for your answer.
The point is that I cannot use a dataview. Once I reset the grid's
datasource, I lose a lot of grid formatting - coloring I do after the
binding, depending on the data each row has. Plus the fact that this
formatting takes quite some time (although I am positive my code is
correct, hope it is a beta performance issue).

The only thing that I need is a checkbox to show some rows of the
datagrid or not, just toggle their visibility on-off. I can do it in
all the rows EXCEPT the first one (getting the aforementioned error).

Thank you in advance for any further help.

Got it.
The currency manager's position is the current datagridview row whose
cell that has focus.
So, I did a ReportGrid.currentCell = ... to a cell whose row is no way
it would hide, and everything worked ok...
