vb.net - Force datagridview call row validating after finish input -

-

i'm creating form bound datagridview inside it. on form_load or row_validating, added new row datagridview by: 

private sub purchaseinrowadd()         'add new row datagridview         dim dtrow datarow = ctype(me.dgvpurchasein.datasource, datatable).newrow()         dtrow.item("invoiceid") = 0         dtrow.item("kindid") = ctype(ctype(me.dgvpurchasein.columns("colpurchasekind"), datagridviewcomboboxcolumn).datasource, datatable).rows(0)("kindid")         dtrow.item("invoicesign") = ""         dtrow.item("invoiceno") = ""         dtrow.item("invoicedate") = new date(objcontroller.processyear, objcontroller.processmonth, 1)         dtrow.item("id") = ctype(ctype(me.dgvpurchasein.columns("colpurchasecustomer"), datagridviewcomboboxcolumn).datasource, datatable).rows(0)("id")         dtrow.item("product") = ""         dtrow.item("price") = "0.00"         dtrow.item("note") = ""         dtrow.item("tax") = ctype(ctype(me.dgvpurchasein.columns("colpurchasekind"), datagridviewcomboboxcolumn).datasource, datatable).rows(0)("tax")         dtrow.item("taxcode") = ctype(ctype(me.dgvpurchasein.columns("colpurchasecustomer"), datagridviewcomboboxcolumn).datasource, datatable).rows(0)("taxcode")         dtrow.item("vat") = ""          ctype(me.dgvpurchasein.datasource, datatable).rows.add(dtrow)     end sub

the problem here is, when user finished input in new row , press enter, row_validating hasn't been fired because there's no row below it. how can force row_validating trigger when user finished input , press enter?

i have found this solution, doesn't suit case because don't want set enable adding true. want handle row adding code instead.

i found solution, subclassed datagridview , override processdialogkey this: 

protected override bool processdialogkey(keys keydata)         {             if(keydata == keys.enter)             {                 keyenterpress(this, new eventargs());             }             return base.processdialogkey(keydata);         }

(i wrote subclass in c#)

then handle key enter press in form 

private sub purchaseincellkeydown(byval sender object, byval e eventargs)         if me.dgvpurchasein.currentrow.index = me.dgvpurchasein.rows.count - 1             if purchaseinrowvalidate(me.dgvpurchasein.currentrow.index, true)                 me.purchaseinrowadd()                 me.deselectpurchasecell(me.dgvpurchasein.currentrow.index)                 me.dgvpurchasein.rows(me.dgvpurchasein.rows.count - 1).cells("colpurchasesign").selected = true             end if         end if     end sub

this line: 

me.dgvpurchasein.rows(me.dgvpurchasein.rows.count - 1).cells("colpurchasesign").selected = true

will trigger row validating
