vb.net - Binding ComboBox to DataTable That is not in Dataset -


i using vb.net develop small application. want bind combobox datatable not in dataset. binding dataset follows: 

bsos=new bindingsource(ds,"tablename")

assume created own distinct table values follows:

tblos = dstaset.tables("computers").defaultview.totable(true, "os")

what want following:

bsos = new bindingsource(tblos)

but error comes: 

unable cast object of type 'system.data.datatable' type 'system.componentmodel.icontainer'.

is there away without adding table dataset?

this should work:

combobox.datasource = tblos combobox.valuemember = "<column name want value>" combobox.displaymember = "<column name value want display in list>"

to update datasource values can this:

dim tblos datatable = combobox.datasource dim dr datarow = tblos.newrow() dr.item(0) = "value" dr.item(n) = "display"

since datatable isn't bound doubt possible update automatically. if keep tblos property, instead of local variable, update combobox gets new row.
