Thanks for the reply. I got one link in which Graph is implemented in Silverlight but that Project doesn't run.

http://www.netfxharmonics.com/2007/05/Reflecting-Graph-Silverlight-Demo.aspx

Everything is done in through Javascript and I cant see xap file in that project.

Can you please tell me is there anyways to convert Javascript code ? This question might be a wrong question but right now Im struggling in implementing graphs.

Please help.

Thanks in advance.

Greetings,

Im not sure if this will help much....but i am currently building a c# class library. We wanted it to be compatable with both asp and silverlight. Our solution was to make the library in compatable with asp. But we use a silverlight enabled WCF service to act as the middle man, which mines data using the library and returns it to the silverlight app.

Just an idea anyways

Cheers,

I think your best bet is dictionary.

using System.Collections.Generic;

void foo() {
   Dictionary<string, string> dict = new Dictionary<string, string>();
   dict.Add("hello", "world");
   dict.Add("foo", "bar");
   if (!dict.Contains("foo")) throw new Exception();
   string world = dict["hello"];
   if (world != "world") throw new Exception();
}

It is not a hashtable... I think it is implemented based on binary tree. For most practical purpose this is good enough. If not, there are many hash table implementations in C++, or even C#.

Thanks for the reply. Im trying to convert that code because I have to create Graph control in Silverlight. I mean Graph not Chart Control.

Where I can Traverse the nodes or from database I can get the values and Draw the Graph.

Can you please help me with this?

Thanks again.

Instead of the Hash Table, Create a class with the columns(in the hash table) as Properties of the class. And use a List<Object> to add the items in the row. for example

public class Graph

{

public int PointX { get; set; }

public int PointY { get; set; }

}

in the function where you want to use the hash table use the following code

List< Graph > myTable = new List< Graph >();

myTable .Add(new Graph(){ PointX=100, PointY=200});

myTable .Add(new Graph(){ PointX=110, PointY=220});

myTable .Add(new Graph(){ PointX=120, PointY=240});

You can then Bind this List "myTable" to a ListBox or ComboBox or DataGrid..

let me know if this helps..

Thanks

Silverlight doesnot support the default visual studio class libraries.

You will have to create Silverlight Class Library project and then add your classes inside that !!!.
