Hi,

Based on my understanding, I think the issue is something about "Locking Architecture & SQL TRANSACTION".

For more information about SQL TRANSACTION, see:

http://msdn2.microsoft.com/en-us/library/aa224738(SQL.80).aspx(Locking Architecture)

Best Regards,

thankJin Yu Jin

i found out other way to resolved this problem like that:

checkbox column have not bound any data field instead by javascript function to check all and checkbox item is checked by autopostback = false.

thank your idea.

Oh,Sorry, I misunderstood you by "everything seem not synchronized.", It should be "everything seem synchronized".

Best Regards,

Array property on a complex return type not deserializing to Array

HI,

I have a WS that returns a complex type let's call itJSONResultWrapper-one of the properties ofJSONResultWrappersay,Result, is an Array of another complex type say,JSONResult.

When this serializes down the wire, it looks like it has serialized correctly, but when it is deserialized back into an object at the client, instead ofResult being an Array orJSONResult,it is an object.

Sure, I can iterate through this and add each element into my array - but should I have to ?

c# code

public class JSONResultWrapper
{
...other props here...
public JSONResult[] Results;
...
}

--8<-----8<-------

[WebMethod]
public JSONResultWrapper GetResults(string SearchKey, string type)
{
JSONResultWrapper Jrw = new JSONResultWrapper();
.....
return Jrw;
}

--8<-----8<-------

JSON (from firebug)

{"AccommodationType":["Hotel","Apartment"],"Allocation":["Named"],"Results":[{"id":"694999631","ds":28,"dp":74,"tn" :4034,"b":3,"c":280460,"s":0,"u":0,"dd":0,"at":0,"al":0,"du":6,"ap":2,"cp":0,"r":"3*","p":"74","ip":1
,"an":"Tophotels Casino Royal","q":"s17056","dl":null,"e":1,"mo":0},{"id":"692909484","ds":28,"dp":74
,"tn":388,"b":2,"c":1701,"s":0,"u":1,"dd":1,"at":1,"al":0,"du":7,"ap":2,"cp":0,"r":"","p":"88","ip":1
,"an":"","q":"6HR1357","dl":"","e":1,"mo":0}]}

Javascript.

--8<-----8<-------

TT.ResultCollection = function(InitValues) {

TT.ResultCollection.initializeBase(this);
......
this.Results = new Array();
.....
}

--8<-----8<-------

_onMethodComplete : function(result, userContext, methodName) {

try{
this.Results = $create(TT.ResultCollection,result);
}

--8<-----8<-------

I end up with this.Results.Results being an Object with properties, rather than an Array.

So far I have tried all sorts of types for Results ion the server but I realised that they were all serializing OK - it is the deserializing that is causing me problems.

What gives?

Cheers, all.

Have a look at http://www.microsoft.com/belux/msdn/nl/community/columns/jdruyts/wsproxy.mspx

You may need to use Jelle Druyts WSDL import modifier to fix the issue/

alternatively, have a look at the ajax-extensions converter class: http://ajax.asp.net/docs/mref/T_System_Web_Script_Serialization_JavaScriptConverter.aspx

Are there any (premade) ajax tools I can use to make a panel slide in from off screen?

I've seen a couple of tools based on animated panels, mainly acordian and other "folding" type effects.

But what I'm after is to have pannels appear from off the side of the screen.

Is there anything outhere that fits the bill or do i need to code my own?

Cheers. :)

Try the Animation extender: http://ajax.asp.net/ajaxtoolkit/Animation/Animation.aspx
