pass datafield type to server for filtering

[mjf200Participant]

Hello,
To perform grid filtering on the server I need to pass the type of each field back as a parameter. Is there an automatic way to do that?

I found this old post:

it describes doing it like this:

data: {
  table: grid, 
  fieldscount: datafields.length,
  fields: datafields  
 },

when I try that in my source I get undefined on datafields, by doing a this.datafields the error goes away but no additional parameter are passed back to the server.

I could possibly list the columns and types again in the data property and they parse the additional parameters on the server to determine the data type of each column but I’m wondering if there is a setting that will automatically include the data type in the filter parameters that are passed.

Thanks

Hello mjf200,

If you are making your Ajax call in the source filter callback, the datafields array will be available as this._source.datafields (this is the data adapter’s instance).

Hi Dimitar, I thought I responded to your message but I don’t see my message. Here it is again.

I am setting the filter property in the source object, like this:

filter: function () {
    $("#jqxgrid").jqxGrid(''updatebounddata'', ''filter'');
},

I don’t quite understand how I would use that function to pass the data type to the server when filtering.

Thanks,
Mike

Hi Mike,

For passing HTTP variables with your Server Calls, look at: http://www.jqwidgets.com/jquery-widgets-documentation/documentation/jqxgrid/jquery-grid-extra-http-variables.htm
