Method One I have used Image datatype as parameter and its working fine.
//Method I

Method Two, here I am trying to save image in database using typed dataset and getting XML from it and passing to stored procdure with XML data type as input parameter. Inside stored procedure I have used OpneXml method to read incoming xml and insert in table. But when I try to retirve the same its not giveing proper output. Even I tryied to map data inserted with Method I its not same in table even the image is selected same.

//Save Image using stored procedure with xml datatype as an parameter.

Below code is used to retive image from database and display in Image Control.
//Retrive Image in Image Control
if (Request.QueryString["ImageID"] == null)
{
ObjSqlConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["CONNECTIONSTRING"].ConnectionString.ToString());
ObjSqlConnection.Open();
ObjSqlCommand = new SqlCommand();
ObjSqlCommand.Connection = ObjSqlConnection;
ObjSqlCommand.CommandType = CommandType.Text;
ObjSqlCommand.CommandText = "TestDisplayPhotograph";
ObjSqlDataAdapter = new SqlDataAdapter();
ObjSqlDataAdapter.SelectCommand = ObjSqlCommand;
ObjDataSet = new DataSet();
ObjSqlDataAdapter.Fill(ObjDataSet);
ObjSqlConnection.Close();
Session["ObjDataSet"] = ObjDataSet;
}
else
{
ObjDataSet = (DataSet)Session["ObjDataSet"];
if (Request.QueryString["ImageID"].ToString() == "Image1")
{
Response.BinaryWrite((Byte[])ObjDataSet.Tables[0].Rows[0][1]);
}
