Passing Ajax.Web.Dictionary ?

Passing Ajax.Web.Dictionary ? -- eLad --

I have tried to do so by:

var dic=new Ajax.Web.Dictionary();
dic.add("x",1.2);

alert(SomeServerMethod(dic).value);
// server side

public bool SomeServerMethod(Dictionary<IJavaScriptObject,IJavaScriptObject> o){
return true;
}

but on every call i get

Message Object reference not set to an instance of an object.

Type System.NullReferenceException

Stack
at AjaxPro.JavaScriptDeserializer.Deserialize(IJavaScriptObject o,
Type type)
at AjaxPro.XmlHttpRequestProcessor.RetreiveParameters()
at AjaxPro.AjaxProcHelper.Run()
TargetSite System.Object Deserialize(AjaxPro.IJavaScriptObject,
System.Type)

Source AjaxPro.2

How can i send such a dictionary?

Thanks!

Hey First of all, thanks for the reply !

I have just downloaded 6.7.11.1 and re-checked the code,
but still getting an error:

// client

var dic=new Ajax.Web.Dictionary();
dic.add("x","y");

ServerFunction(dic);

// server

public bool ServerFunction(Dictionary<string,string> dic) {
return true;
}
Message
Object reference not set to an instance of an object.

Type
System.NullReferenceException

Stack

Type type)
at AjaxPro.XmlHttpRequestProcessor.RetreiveParameters()

TargetSite
System.Object Deserialize(AjaxPro.IJavaScriptObject, System.Type)

Source
AjaxPro.2
also tried to replace <string,string> with
<IJavaScriptObject,IJavaScriptObject>, same error.

Thank you.

Hi,

sorry, I did't fixed this bug, yet. I'm still over it, it is strange to create objects from generic types... I will give you a note if it is fixed. Please stand by...

Ok,
That's great, thanks.

I just want to pass an object {name:"foo",type:"bar",number:7.62} and read it as a Hashtable or so (o

.ToString()=="foo" /
((double)o

)==7.62D). Is it possible anyhow?
Meanwhile I pass an Ajax.Web.DataSet.

-- MichaelSchwarz --

You can use following code instead:
var o = new Object();
o.name = "foo";
o.type = "bar";
o.number = 7.63;

AjaxClass.AjaxMethodX( o, mycallback );
On the server-side code use:

public static string AjaxMethodX(JavaScriptObject ht)
{
return ht

.Value;
}

Michael

That's great.

Some little questions:
Why does strings comes out with quots?
And is there a way to send a datetime in a JavaScriptObject?

This is the o

.Value new Ajax.Web.Dictionary("System.Collections.Generic.Dictionary`2[[System.String,
mscorlib, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089],[AjaxPro.IJavaScriptObject, AjaxPro.2,
Version=6.7.11.1, Culture=neutral,
PublicKeyToken=4735ae9824c7d3ec]]",

)

I tried also to use JavaScriptDeserializer.DeserializeFromJson<DateTime>(o

.Value)
but got an error.

You do great work. I appreciate it!
