hi, im using vb.net 2005
how can i add values to arraylist & how can i retreive those values into one variable or windowsdatagrid view

Wow, this is poor understanding, and I can only presume you have not read a single line from the MSDN library, and I do hope you aren't working for Civil Defence:

Dim arrList as New ArrayList()

arrList.Add(10)

Dim dGrid As New DataGridView()

dGrid.DataSource = arrList
