The first: In database you create table menu in table menu have 4 colums 1. ID int identity primary key, 2. Name(50) not null, 3. Images(200), 4. Description (100), The second: You have connect string. if you don't know connect string you google with keyword "connect string" and go to box "SQL Server" and then put out connect string. .Often connect their string in the file declarations global.asax And then in file website you created or datalist and gridview to collect data from sql server.
