ASP.Net MVC 2.0: EditorFor setting name via attributes

问题

Just wondering how do I mimic the following using attributes...

<%= Html.EditorFor(x => x.SportProgramIdList, "FormMultiSelectDropDownList", "SportProgramIds")%>

I know I can specify the template by using [UIHint("FormMultiSelectDropDownList")] but I am left with the problem with how to set the name...

Cheers Anthony

回答1:

I Guess you'll have to create your own CustomAttribute UINameAttribute. You could use the ModelMetadata to keep your attribute and then I'm not sure what would be the best way to get it, i guess you would have to overide the HtmlHelper.EditorFor Extension without the parameter and pass your attribute to the next.

I'm too lazy and to tired to try for a more complete answer.

look at :

Use the objectAttributes argument

<%= Html.EditorFor(x => x.SportProgramIdList, "FormMultiSelectDropDownList", new { id="SportProgramIds" }) %>>

you can use this to set any of the html input attributes
