Question

Can anyone show me how to stop my Datagridview from scrolling to first row after every cell update?

I'm using timer to auto refresh cell data.

Hi @Martin Nikodijevic ,

Create a global variable that records the currently selected row and column indexes, and restores the previous selected state of the cell when the DataGridView is refreshed during the timer tick event.

For example:

int selectedRowIndex = -1;
int selectedColumnIndex = -1;

private void RecordSelectedCell()
{
    if (dataGridView1.SelectedCells.Count > 0)
    {
        selectedRowIndex = dataGridView1.SelectedCells[0].RowIndex;
        selectedColumnIndex = dataGridView1.SelectedCells[0].ColumnIndex;
    }
    else
    {
        selectedRowIndex = -1;
        selectedColumnIndex = -1;
    }
}


private void timer1_Tick(object sender, EventArgs e)
{

    RecordSelectedCell();

    if (selectedRowIndex >= 0 && selectedColumnIndex >= 0 &&
        selectedRowIndex < dataGridView1.Rows.Count &&
        selectedColumnIndex < dataGridView1.Columns.Count)
    {
        dataGridView1.ClearSelection();
        dataGridView1.Rows[selectedRowIndex].Cells[selectedColumnIndex].Selected = true;
    }
}

Best Regards.
