DataGridView.CurrentCell (Set)

[Michel Walsh]

Someone has an example, C#, about how to set the cell(int row, int col) as
the current cell for a DataGridView. The example, in the help file, about
DataGrid.CurrentCell Property (Set)

myGrid.CurrentCell = new DataGridCell(1,1);


does not work, fro a DataGridView, since we cannot create a DataGridView
Cell while specifying only its row and column.

Sorry for the bandwidth, just found that I just have to point to that said
cell, after all... doh. No need to 'create' one, as the example from
DataGrid leads us to think. The following works:


dataGridView1.CurrentCell = dataGridView1.Rows[iRow].Cells[iCol];

Michael,

There are more succinct ways of doing this:

dataGridView1.CurrentCellAddress = new Point(1, 1);

Or, if you wish:

dataGridView1.CurrentCell = dataGridView1[1, 1];

Both should have the same effect, although the top example will help
prevent unsharing of rows, which is good when you are using the grid in
virtual mode.

If I can ask you one more question.


While

dataGridView1.CurrentCell = dataGridView1[1, 1];

is fine for me, if I consider dataGridView[1,1] is a reference (a pointer)
to an existing cell, and then CurrentCell property just 'set the focus' on
that 'object reference' it got as its 'value', I fail to see how:


dataGridView1.CurrentCellAddress = new Point(1, 1);


could even work, since

new Point(1, 1)

is also a reference, but totally unrelated to any cell-references
(cell-pointers) owned by the dataGridView object. With this, in
consideration, can you explain the inner-working of


dataGridView1.CurrentCellAddress = new Point(1, 1);




Thanks for your time

[Andrus]

dataGridView1.CurrentCellAddress = new Point(1, 1);

causes error
'System.Windows.Forms.DataGridView.CurrentCellAddress' cannot be assigned
to -- it is read only


So how to use it ?

Andrus.

Michel,

As you and Andrus pointed out, you the CurrentCellAddress property is
read-only, so you can't set it.

So only the first example I gave is valid.
