How To Access Javascript Multidimensional Array In Mvc Controller

I have to pass array of filters like this: Script Code: return { CustomFilter: options.filter.filters }; ++++++++++++++++++++++++++++++++++++++++++++++++ From Firebug: CustomFilte

Solution 1:

It looks like an error with model structure.

publicclassMyViewModel
{
    public Filter[] CustomFilter { get; set; }
    publicstring Filter { get; set; }
    publicstring Group { get; set; }
    publicint Page { get; set; }
    publicint PageSize { get; set; }
    publicint Sort { get; set; }
}

Try to use this type for model binding.

public ActionResult ReadOperation(MyViewModel model)

Solution 2:

If you are using ASP.NET MVC 4, and cannot change the parameter names, maybe you can define a custom model in this way:

publicclassMyViewModel
{
    public Dictionary<string,string>[] CustomerFilter { get; set; }
    publicstring filter { get; set; }
    publicstringgroup { get; set; }
    publicint page { get; set; }
    publicint pageSize { get; set; }
    publicint sort { get; set; }
}

Then, at the controller:

public ActionResult ReadOperation(MyViewModel model){ ... }

It seems that the notation used in the parameters generated by your grid is for dictionaries. Haven't tried a collection of Dictionaries, though.

Solution 3:

In the post, try to send the data as this:

CustomFilter[0].Field      ItemName
CustomFilter[0].Operator   startswith
CustomFilter[0].Value      testing Value

CustomFilter[1].Field      BrandName
CustomFilter[1].Operator   startswith
CustomFilter[1].Value      testing Value 1

And at the controller:

public ActionResult ReadOperation(Filter[] CustomFilter)

Having a Filter class defined as:

publicclassFilter
{
    publicstring Field { set; get; }
    publicstring Operator { set; get; }
    publicstring Value { set; get; }
}

(Be careful with the capital letters).

Or if you want to use the model approach, as Ufuk suggests, and having the same Filter class:

• Model:

  publicclassMyViewModel
  {
      public Filter[] CustomerFilter { get; set; }
      publicstring Filter { get; set; }
      publicstring Group { get; set; }
      publicint Page { get; set; }
      publicint PageSize { get; set; }
      publicint Sort { get; set; }
  }
  

• Parameters in POST:

  CustomFilter[0].Field      ItemName
  CustomFilter[0].Operator   startswith
  CustomFilter[0].Value      testing Value
  
  CustomFilter[1].Field      BrandName
  CustomFilter[1].Operator   startswith
  CustomFilter[1].Value      testing Value1Filter                     ItemName~startswith~'12'~and~BrandName~startswith~'123'Group
  Page                       1
  PageSize                   15
  Sort
  

• Controller

  public ActionResult ReadOperation(MyViewModel model)
