Question

I\'m trying to execute a web service which returns a DataTable with the following piece of code:

$.ajax({  
    type: \"POST\",  
    url: url,  
    data: d         


        

Answer 1

It works for very well for me with a WebService

    Imports System.Web.Script.Serialization

    Dim wsServicio As New ["YourWsInstance"]
    Dim dsInstEstado As New DataSet
    Dim sSql As String

    sSql = " Your SQL Statement"
    dsInstEstado = wsServicio.getData("YourWebServiceParameters")
    Dim jsonString = DataTableToJSON(dsInstEstado.Tables("CA_INSTITUCION"))
    Return Json(jsonString, JsonRequestBehavior.AllowGet)

    Function DataTableToJSon(dt As DataTable) As Object
    Dim arr(dt.Rows.Count - 1) As Object
    Dim column As DataColumn
    For i = 0 To dt.Rows.Count - 1
        Dim dict As New Dictionary(Of String, Object)
        For Each column In dt.Columns
            dict.Add(column.ColumnName, dt.Rows(i)(column))
        Next
        arr(i) = dict
    Next
   Return arr
 End Function
