  • Show Image data in gridview using Handler in asp.net:
    Working steps to show Image data in gridview using Handler in asp.net:
    1. Take asp.net new project.
    2. I have done a CRUD operation where I have saved image in folder location of the project and save the image path in the database with the productive way to save the image in web application
    3. Do insert update delete data and test everything is working fine, you will find all process and code of this CRUD operation in my previous video tutorial. Check the link below.
    4. Then Insert some sample data to SQL table with image
    5. Take a gridview and a button to show all data. Create click event of the button.
    6. Write code in button to show all data with Entity data model object
    7. Take a Generic Handler and write code with dbcontext object.
    8. Edit gridview data field with and Image field.Set height and width.
    9. Stop Auto Generated column by uncheck.
    10. Set EmpID in DataImageUrlfield and in DataImageUrlformatstring= Set ImageHandler with Primary key ID.
    11. Run, It will show the Image in datagridview
    12. We can show image in datagridview by itemtemplate by setting ImageUrl Code Expression with Eval method and pass ID and Handler page name.
    13. We can write it in two ways, I have showed in video.
    14. Set Image width and height size by controlstyle properties.
    15. Run and check. Best of luck
