winapp: inserting a rowcount column in a datagridview

[nev]

basically, what i'm trying to do is to place a rowcount column in my datagridview.

my dgv already has values. i'm thinking i can use dgv.columns.ins ert(0, ???) to place the rowcount column in the dgv.

i did...

dim dtgvc as datagridviewcol umn

[what should i do here?]

dgv.columns.ins ert(0,dtgvc)

[nev]

heres an update, i'm able to add a new column already.

dtg.datasource = [one of my datatables]

dim dtgtxt as new datagridviewtex tbox

dtgtxt.name = "colNo"
dtgtxt.headerte xt = "No"

dtg.insert(0,dt gtxt)

for i as integer = 0 to dtg.rows.count - 1
dtg("colNo",i). value = i
next

the problem is, the rowcount values are not placed in the dtg.
