Id Request Id File Name
1 12 Abc.jpg

Now, I want that If I delete any file from the Gridview(which has all uploaded files), I want that file to be deleted from database table also.Currently on Deleting file from Gridview, files from "Folder" are deleted not from Database.
Forms Data Controls :: Validating An Entire Column In Gridview Before Data Is Saved In Database?
Mar 24, 2010I am using a bound gridview in ASP.NET 2.0. The gridview has the ability to edit/update and insert rows. One of the columns holds a number which represents a percentage. What I cannot figure out is how to ensure that all the rows in the gridview total 100% before being able to send the updates or newly inserted data to the database.
For example say there are 5 rows in the gridview, each row has 20% stored in the column so it adds up to 100% which is fine, the data is updated/inserted in the database. But say each row only had 15% totalling 75%, the user should not be able to send the updated/inserted data to the database until either they add a new row with a percentage of 25 or they edit the other rows for a cumulative total of 100%
I am not familiar with javascript or AJAX

View 1 RepliesForms Data Controls :: Can't Modify Data In Gridview After Imported From .csv
Feb 20, 2010I have a gridview that displays data from my online database. Works great. edit/update/delete functions work also.
I decided to import data into my database through my SQL Server web admin. It worked fine, and the imported data now shows up in my gridview, but once I decide to use my gridview edit/delete buttons, the grid won't update the data or delete the rows. It will however properly function on the rows that were manually entered with the gridview and/or in visual studio.
