VS2500 - How to set 'currently viewed rows' ??

[frostbb]

Greetings:

Working on a VS2005 C# program.

I have a DataGridView control that is bound to dataviews generated by
various database queries. i.e. the user enters search criteria and the
query results end up in the grid. The DataViewGrid is Read Only. The user
has the option of selecting a single record from the grid which causes all
of the associated database record values to become available for edit in an
area outside of the DataViewGrid.

Once the user completes the data updates and saves the data back to the
database I >refresh << the DataGridView to reflect the updates.

I have figured out how to re-select the DataGridView record that was
updated.

How do I ensure that the selected/updated record is visible in the
DataGridView window after the requery ???

i.e. if the window can display 10 rows and the data set is 30 rows long ...
how to I ensure that row #21 appears in the DataGridView window ??

Thanks in advance.

Hi Oregon,

Based on my understanding, your question is how to ensure a particular
DataGridViewRow to be visible in a DataGridView. If I'm off base, please
feel free to let me know.

You have two options to do this.

One option is to set the DataGridView's CurrentCell property to the first
cell of the specified DataGridViewRow . Once we set a DataGridViewRow as the
current row, this row will scroll into the visible area of the
DataGridView. The following is a sample which sets the 5th DataGridViewRow
as the current row:

this.dataGridVi ew1.CurrentCell = this.dataGridVi ew1.Rows[4].Cells[0]

The other option is to set the DataGridView's
FirstDisplayedS crollingRowInde x property to the row index of the specified
DataGridViewRow . The following is a sample:

this.dataGridVi ew1.FirstDispla yedScrollingRow Index = 4;

Hope this helps.
If you have any question, please feel free to let me know.

Sincerely,
Linda Liu

Linda,

Thank you for the quick reply and aplogies for the late reply on my
part.

I used your " this.dataGridVi ew1.CurrentCell =
this.dataGridVi ew1.Rows[4].Cells[0]" option and it worked just as I
had hoped. Now when a user updates data derived from a specific
DataGridView row, I can ensure that the updated information appears as
one of the rows in the refreshed DataGridView display window.

Many Thanks !

Linda,

I am using the FirstDisplayedS crollingRowInde x to scroll the view to the
bottom without changing the selected "CurrentCel l". If the window is small
before the scroll is called, I get an InvalidOperatio nException "No room is
available to display rows" event. How can I avoid this error and yet have
the grid scroll to the bottom without changing the current cell?
