.net - DataGridView select Row Error -


i build auto-suggestive search textbox , dgv. works fine, besides wanna have 2 buttons offer functionality go 1 row or down. have know, while searching set rows don't contain search-string .visible = false.

in theory should work this:

private sub tsbdown_click(sender object, e eventargs) handles tsbdown.click     dgvma        if dgvma.rowcount > 0             dim mydesiredindex integer = getnextvisiblecell(dgvma.currentrow.index)              dgvma.clearselection()             dgvma.currentcell = dgvma.rows(mydesiredindex).cells(1)             dgvma.rows(mydesiredindex).selected = true         end if     end end sub  private function getnextvisiblecell(currentrow integer) integer     dgvma         = currentrow .rows.count - 1             if .rows(i).visible = true                 msgbox(i & ": " & .rows(i).visible)                 return                 exit             end if         next          return currentrow     end end function

but never ever row gets selected. multi-select set false, , fullrowselect true. when click on row manually or gets selected keyboard printed properly.

what doing wrong?

this should work:

private sub tsbdown_click(sender object, e eventargs) handles tsbdown.click     dgvma         if dgvma.rowcount > 0 , dgvma.currentrow.index + 1 < dgvma.rows.count             dim mydesiredindex integer = getnextvisiblecell(dgvma.currentrow.index + 1)              dgvma.clearselection()             dgvma.currentcell = dgvma.rows(mydesiredindex).cells(1)             dgvma.rows(mydesiredindex).selected = true         end if     end end sub  private sub tsbup_click(sender system.object, e system.eventargs) handles tsbup.click     dgvma         if dgvma.rowcount > 0 , dgvma.currentrow.index <> 0             dim mydesiredindex integer = getnextvisiblecell(dgvma.currentrow.index - 1)              dgvma.clearselection()             dgvma.currentcell = dgvma.rows(mydesiredindex).cells(1)             dgvma.rows(mydesiredindex).selected = true         end if     end end sub  private function getnextvisiblecell(currentrow integer) integer     dim integer     dgvma         = currentrow .rows.count - 1             if .rows(i).visible = true                 ' msgbox(i & ": " & .rows(i).visible)                 return                 exit             end if         next          return currentrow     end end function

p.s. didn't check code gets next visible cell seems ok , row selection works fine

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
