@Html.CheckBoxListFor, setting the tab index for each checkbox?

3rd Party Component: MvcCheckBoxList

I have this strongly typed lists of check-boxes, I just want to set their tab index. How can i do this?

   @Html.CheckBoxListFor(model=>model.agentTypeViewModel.PostedAgentTypes.AgentTypeId,
                                                          model=>model.agentTypeViewModel.AvailableAgentTypes,
                                                          agent=>agent.Id,
                                                          agent=>agent.Name,
                                                          model=>model.agentTypeViewModel.SelectedAgentTypes,
                                                          Position.Vertical)

I was successfully able to set my other controls tab-index, @Html.TextBoxFor(p=>p.TRU, new {tabindex = 28, id="txtTRU"}) works fine; but apparently if I don't set a tab-index for the check-boxes, pressing tab will directly move cursor to the list of check-boxes, completely ignoring all other 26 fields that come first...

Any suggestions?

It looks like you're using the MvcCheckBoxList component. According to the documentation (not sure why you didn't bother to read this):

MvcCheckBoxList

You would just do this:

@Html.CheckBoxListFor(model => model.agentTypeViewModel.PostedAgentTypes.AgentTypeId,
                      model => model.agentTypeViewModel.AvailableAgentTypes,
                      agent => agent.Id,
                      agent => agent.Name,
                      model => model.agentTypeViewModel.SelectedAgentTypes,
                      Position.Vertical,
                      x => new {tabindex = 28})
