This is a 2 part question

First Part

I have a multi-select datagridview that has 2 columns.  I need to read the two columns of each selected item into an arraylist.  

Part 2

Can I create a Property typed as an ArrayList and save the ArrayList to that Property?

try this

        Dim ArrList As ArrayList = New ArrayList()
        Dim i As Integer = 0
        Dim Col as integer
        
        For i = 0 To Me.dataGridView1.SelectedRows.Count
            ArrayList.Insert(0, Me.dataGridView1.SelectedRows(i))

        Next

Open in new window

This is for one column ...You should add one more loop
For Col=0 to Me.DatagridView.Column.Count-1

I am trying your solution, but I must be doing something wrong.

First I fill the datagridview with values

Then while holding down the Shift key I pick a couple of rows

Then I have a button and the click event code is

Dim ncount As Integer
        ncount = Me.DataGridView1.SelectedRows.Count
        MsgBox(ncount)

The MsgBox value is always 0 no matter how many rows I select

Any ideas why SelectedRows won't return a value?

Thanks
