Answer / .....
initially while inserting image into database take the
database field in oracle as BLOB in sql as image
during insertion convert the image file into bytes and
insert it into the database
during the display of image in datagrid take a image
template and display the converted values
sample code to get the image:
public byte[] spic(string cm,int id)
{
con = new OracleConnection(cm);
OracleCommand cmd = new OracleCommand("select
photo from kir_image where eid= "+id +" ", con);
con.Open();
byte[] img = (byte[])cmd.ExecuteScalar();
con.Close();
return img;
}
use Response.BinaryWrite to display the image

when i want to use asp.net configuration for creat users and roles i recived this message: There is a problem with your selected data store.

Click the button below to be redirected to a page where you can choose a new data store. The following message may help in diagnosing the problem: Unable to connect to SQL Server database. when i clicked the choose data source button that give me another message that is this: Use this page to configure how Web site management data such as membership is stored. You can use a single provider for all the management data for your site or you can specify a different provider for each feature.
