Aspdotnetsiva: How to Save Image Along With Details Into Database in ASP.NET

Here we will create three web pages as Default.aspx, employee.aspx and image.aspx. After inserting the records in the Default.aspx page the control moves to employee.aspx where we can see all the records of the employee with images.

Default.aspx
