Security Framework

I've created a new repository on GitHub.
The project is a security framework for asp.net mvc projects.
You can find it th following address on GitHub:

I'll update this post periodically to make a useful guide to use it in your projects.

Have fun. 

Consuming a WCF with error: "The caller was not authenticated by the service"

Consuming a WCF service when it hosted on a work group server may cause raise some errors such as: "The caller was not authenticated by the service".
I tackled it by adding the following lines to my code:

Gridview Sorting Problem

When you bind a List to a Gridview, you can not sort it, because your data source is not a Dataset, Dataview or DataTable. So you should convert your data source (List) to a Dataset for example.


You can do it such as following code:

    1 public static DataSet dsSearch()

    2 {

    3 

    4     DataTable dtTelcoCenter = new DataTable();

    5     dtTelcoCenter.Columns.Add("Id", typeof(int));

    6     dtTelcoCenter.Columns.Add("City", typeof(string));

    7     dtTelcoCenter.Columns.Add("Capacity", typeof(int));

    8 

    9     IList<Telco> telcoCenter = Search(centerName, Prefix);// Search method return a list

   10 

   11 

   12     foreach (Telco telco in telcoCenter)

   13     {

   14         DataRow rowTelcoCenter = dtTelcoCenter.NewRow();

   15         rowTelcoCenter["Id"] = telco.Id;

   16         rowTelcoCenter["City"] = telco.City;

   17         rowTelcoCenter["Capacity"] = telco.Capacity;

   18         dtTelcoCenter.Rows.Add(rowTelcoCenter);

   19     }

   20     DataSet dsTelcoCenter = new DataSet();

   21     dsTelcoCenter.Tables.Add(dtTelcoCenter);

   22     return dsTelcoCenter;

   23 }

You can bind this Dataset to your Gridview data source
