vb.net - Button click on RepositoryItemButtonEdit in gridview doesn't trigger any events in DevExpress -

i have gridview 3 columns multiple rows. first 2 columns consists of client's id number , client's name. third column repositoryitembuttonedit button that, when clicked, delete client row.

i've declared repositoryitembuttonedit following way.

dim withevents buttondelete repositoryitembuttonedit buttondelete = new repositoryitembuttonedit  buttondelete.texteditstyle = texteditstyles.hidetexteditor buttondelete.buttons(0).kind = buttonpredefines.glyph buttondelete.buttons(0).caption = "supprimer" addhandler buttondelete.click, addressof me.button_click 

i've added third column following way.

dim unbcolumn gridcolumn = gvexception.columns.addfield("delete")                 unbcolumn.visibleindex = gvexception.columns.count                 unbcolumn.columnedit = buttondelete                 gvexception.optionsview.showbuttonmode = devexpress.xtragrid.views.base.showbuttonmodeenum.showalways 

the 'button click' event captured following way:

private sub button_click(byval sender system.object, byval e eventargs) handles buttondelete.click      messagebox.show("hello world") end sub 

when launch application, see 'delete' button each row.

problem: however, 'hello world' messagebox when click on 'delete' button first row, not when click on 'delete' button other rows.

add buttondelete.buttonpressed event instead of buttondelete.click event.

what have tried below , working fine:

dim buttondelete new repositoryitembuttonedit  buttondelete.buttons.clear() buttondelete.buttonsstyle = borderstyles.ultraflat buttondelete.texteditstyle = texteditstyles.hidetexteditor  dim edtrbtn editorbutton = new editorbutton() edtrbtn.kind = buttonpredefines.glyph edtrbtn.caption = "supprimer"  addhandler buttondelete.buttonpressed, addressof repositoryitembuttonedit_pressed  buttondelete.buttons.add(edtrbtn) 

pressed event:

private sub repositoryitembuttonedit_pressed(sender object, e buttonpressedeventargs)  ''' logic here  end sub 

it should work. rest goes ok.
