How to get current row of datagridview values when clicking on button?

I have a View Model in which my data is stored to be used on the presenter and window. However, I now need to get (when pressing a button) the current row's results on the grid into my view model. I first used the mouse double click event, but the requirements changed from that to a button on the form:

private void dgvResults_CellMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e)
    {
       if (this.colOrderNo.Index != e.ColumnIndex || e.RowIndex < 0) return;

       var auditOrder = (PurchaseOrdersTrackingViewModel) this.dgvResults.Rows[e.RowIndex].DataBoundItem;
       this.AuditOrderKey = $"{auditOrder.OrderNo}|{auditOrder.ItemNo}|{auditOrder.WarehouseId}|{auditOrder.ItemSequence}";
    }

That's my old code. Now I need that here:

private void btnAuditLog_Click(object sender, EventArgs e)

Not sure how to refer to the RowIndex without the DataGridViewCellMouseEventArges event. I tried the CurrentRow property, but it doesn't do the job.

Just another question on the fly, if someone could assist with that as well, how do I get a value from one form to another, spesifically a properties value. It's not on the grid, in a control. It's basically just public string order that's all. I set the value on one form, then need it for query filtering on another. Let me know if you need anything else.

Use the SelectedRows property of the DataGridView. Assuming that you set your DataGridView as MultiSelect = false; and SelectionMode = FullRowSelect;

if (dgvResults.SelectedRows.Count > 0)
{
   dgvResults.SelectedRows[0].Cells["yourColumnName"].Value.ToString();
}

In your button click event, it will look like this. (Assuming that your button name is btnEdit)

private void btnEdit_Click(object sender, EventArgs e)
{
    if (dgvResults.SelectedRows.Count > 0)
    {
       string selectedValue = dgvResults.SelectedRows[0].Cells["yourColumnName"].Value.ToString();
    }
}

You want to use the SelectedRows property of the DataGridView. It tells which row is selected. In this case, you seem to want the first selected row (since you have a single property called this.AuditOrderKey).

The column order no to longer matters in this context.

 if (dgvResults.SelectedRows.Count == 0) return;

 var auditOrder = (PurchaseOrdersTrackingViewModel) dgvResults.SelectedRows[0].DataBoundItem;
 this.AuditOrderKey = $"{auditOrder.OrderNo}|{auditOrder.ItemNo}|{auditOrder.WarehouseId}|{auditOrder.ItemSequence}";

If you don't have selected rows, CurrentRow is an option:

 if (dgvResults.CurrentRow == null) return;

 var auditOrder = (PurchaseOrdersTrackingViewModel) dgvResults.CurrentRow.DataBoundItem;
 this.AuditOrderKey = $"{auditOrder.OrderNo}|{auditOrder.ItemNo}|{auditOrder.WarehouseId}|{auditOrder.ItemSequence}";
