Hello,
For reference, I'm using DataTable 2.0.6
I can't seem to make the DataTable call the function in aspx webforms in visual basic.
This method works:
$.ajax({
type: 'POST',
url: 'Index.aspx/TempGetEmployeeData',
data: JSON.stringify({ Sqloption: 21 }),
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (response) {
var parsedjsonChangeLogData = response.d;
$('#TempEmployeeTable').DataTable({
data: parsedjsonChangeLogData
});
}
});
but this method doesn't:
$('#TempEmployeeTable').DataTable({
ajax: {
type: 'POST',
url: 'Index.aspx/TempGetEmployeeData',
data: JSON.stringify({ Sqloption: 21 }),
contentType: 'application/json; charset=utf-8',
dataType: 'json'
}
});
I also tried removing the type and change it to 'GET', removing contentType, and changing the dataType into text then used a success function to output it in the console.log but the output is the whole html file.
I tried debugging the function, but it doesn't go to the function itself.
Here is the function.
<WebMethod()>
Public Shared Function TempGetEmployeeData(sqlOption As Integer) As String
Dim dt As New DataTable()
Using connection As New SqlConnection(SQLConnStr)
Using command As New SqlCommand("someStoredProcedure", connection)
command.CommandType = CommandType.StoredProcedure
command.Parameters.AddWithValue("@pOption", sqlOption)
connection.Open()
Using SQLresult As SqlDataReader = command.ExecuteReader()
dt.Load(SQLresult)
End Using
End Using
End Using
Dim jsonResult As String = JsonConvert.SerializeObject(dt)
Return jsonResult
End Function
Any help will be much appreciated. Thank you

Ah! Your server is returning the cunning Microsoft JSON as a string wrapped in another JSON object. I've never understood why they did that! Glad to hear you got the solution though
.
DataTables 2.1 is going to do that automatically (I've actually already committed that change - plenty more for 2.1 to be done though).
