vb.net - data from datagridview not displayed into textbox (Visual Studio 2010) -

i've been dealing hours!!! have 2 forms: in 1 form (form1) have layout textboxes, etc... in other (datagrid_form2) have datagridview choose item, doubleclickcell event, loaded in specific textbox of first form (form1).

i have button next textbox of form1 call datagrid_form2, once element in datagrid_form2 chosen textbox of form1 loaded value.

  public sub data_celldoubleclick(byval sender object, byval e system.windows.forms.datagridviewcelleventargs) handles data.celldoubleclick      dim form1panel new form1      form1panel.txtmybox.text = mydata.selectedcells.item(0).value.tostring      debug.writeline(form1panel.txtmybox.text )      me.close()  end sub 

as can see have celldoubleclick event should load value of selected cell textbox of form1, doesn't display in textbox(txtmybox). in debug value chosen correctly, not problem of code, value not being passed @ textbox.

any ideas? hints?

thanks in advance

edit: not clear questions how want achieve ask. have form datagridview (i name frmdgv) , second form (form1) want show cell content yours datagrid. form (form1) opened? or want open new 1 each time double click? , if want open each time want multiple instances or 1 in modal ?
i'll try include everything:

->the form open each time
frmdgv

public sub data_celldoubleclick(byval sender object, byval e      system.windows.forms.datagridviewcelleventargs) handles data.celldoubleclick     dim f1 new form1    f1=directcast(mlinkform1,form1)    f1.txtmybox.text = mydata.selectedcells.item(0).value.tostring    'if want open form1 each time double click in cell     f1.show     'if want modal style info    'f1.showdialog    'f1.dispose end sub 

->the form open (i wouldn't follow this)
frmdgv

   private mlinkform1 form1 public property linkform1              return mlinkform1      end     set(value)         mlinkform1  = value     end set end property 

'when open form first time set:

 dim f1 new form1  mlinkform1=f1  f1.show  public sub data_celldoubleclick(byval sender object, byval e      system.windows.forms.datagridviewcelleventargs) handles data.celldoubleclick    dim f1 new form1    f1=directcast(mlinkform1,form1)    f1.txtmybox.text = mydata.selectedcells.item(0).value.tostring end sub

 private mlinkform1 form1    public property linkform1               return mlinkform1       end      set(value)         mlinkform1  = value      end set end property  public sub data_celldoubleclick(byval sender object, byval e      system.windows.forms.datagridviewcelleventargs) handles data.celldoubleclick     linkform1.txtmybox.text = mydata.selectedcells.item(0).value.tostring     me.close() end sub
