ajax - MVC.NET, JQuery - How to submit a form that is made up of a JQuery datatable with rows that contain checkboxes and text inputs? -

i have jquery datatable has multiple rows contain checkboxes , text input fields. object select rows have checkboxes checked , submit them via ajax. able "id" attribute of checkboxes checked, how values (labels , text inputs) of columns in rest of row?

i need post these action via ajax call. how should go doing , how catch these values in post action?

i have student model.

public class student {  public string studentid { get; set; } public string firstname { get; set; } public string lastname { get; set; }  } 

the view bound model (@model project.models.ienumerable<student>) , datatable generated following:

<table> <thead> <tr> <td>select</td> <td>studentid</td> <td>firstname</td> <td>lastname</td> </tr> </thead> <tbody> <tr>     foreach (var student in model)     {     <td><input type="checkbox" id="@student.studentid"/></td>     <td>@student.studentid</td>     <td>@student.firstname</td>     <td><input type="text" value="@student.lastname"/></td>     } </tr> <tbody> </table> 

the last name field editable, , rows have checkbox checked should updated in database.

so when submit form, in post action, this?

[httppost] public actionresult updatestudent(ienumerable<student> students) {  } 

i have tried above method, have not had success. suggestions?

you cannot use foreach loop because generates duplicate name attributes without indexers , therefore can't bound collection (it generates invalid html because of duplicate id attributes). must use either for loop , make model ilist<student> or custom editortemplate typeof student.

since unchecked checkboxes not post value, textboxes will, need start creating view model (say) bool isselected property can bind using @html.checkboxfor() , ensure value posted matches corresponding textbox.

public class studentvm {     public string id { get; set; }     public string firstname { get; set; }     public string lastname { get; set; }     public bool isselected { get; set; } } 

then in view

@model list<yourassembly.studentvm> @using (html.beginform()) {     <table>         ....         <tbody>             for(int = 0; < model.count; i++)             {                 <tr>                     <td>@html.checkboxfor(m => m[i].isselected)</td>                     <td>                         @html.hiddenfor(m => m[i].id)                         @html.displayfor(m => m[i].id)                     </td>                     ....                     <td>@html.textboxfor(m => m[i].lastname)</td>                 </tr>             }         </tbody>     </table>     <input type="submit" ... /> } 

and controller methods might like

public actionresult updatestudent() {     list<studentvm> model = db.students.select(s => new studentvm     {         id = s.studentid,         firstname = s.firstname,         lastname = s.lastname     });     return view(model); }  [httppost] public actionresult updatestudent(list<studentvm> model) {     var selectedstudents = model.where(s => s.isselected);     // save , redirect }
