CurrencyManager?

[User (Old forums)]

#13362 |

Excuse my bad english :$

my column(5):

0
1
2
3

after changed (moved) 3

0
0.99 (ex 3)
1
2

After an order by column(5) (order automatic by my DataTable) I want set the value of the cell(5) like the row.index.

I can’t do it because the Row.index that I view in the grid isn’t the index of my record

For i As Int32 = 0 To Grid1.DataRows.Count – 1
Grid1.DataRows(i).Cells(5).Value = i ‘<<<<<<< if i = 1 the DataRows(i) isn’t the first row that I see in the grid!? It’s always index of record 2!
Next

I will need of the CurrencyManager?

Code, plz 🙂

bye

PRECISING:

If I change also the first record:

0.99 (ex 3)
0
1
2

For i As Int32 = 0 To Grid1.DataRows.Count – 1
Grid1.DataRows(i).Cells(5).Value = i ‘<<<<<<< if i = 0 the DataRows(0) isn’t the first row that I see in the grid(0.99 – ex 3)!? It’s always index of old record 0 (that now i see in the second row (index = 1)!
Next

Thanks!

If I understand you correctly, you have a mechanism to reorder the DataRows by sorting on a (hidden?) column.

You can’t use the <b>Index</b> property of the DataRow, because that’s not the visible index: it never changes. Try this:<code>Grid1.BeginInit()
Dim rows As Xceed.Grid.Collections.ReadOnlyDataRowList = Grid1.<b>GetSortedDataRows</b>(True)
<i>’ rows is a list of the sorted DataRows</i>
For i As Int32 = 0 To rows.Count – 1
rows.Item(i).Cells(5).Value = i
Next
Grid1.EndInit()</code>
