Asp net gridview rowupdating newvalues empty Adult cam chinese web
Here is some relevant code - this is the Grid in - nothing specified so if any changes occur in the underlaying DB no aspx changes will be required (the idea that is being tested) That should give you back a valid Values collection.
We are working on developing a methodology to port our old but good VB6 App to ASP and I am on a learning curve here so I am sure I have missed something (hopefully! This is just exploration for now so I can develop all the tools for the job at hand.
I've seen a number of "answers" which only provide the text in the selected row of a gridview, or the header text which both do not answer the question that was asked... If you were going to do audits of updates in a system and wanted to compare old values and new values and only update if they change and want to indicate which field was updated how do you show the database table field name at the index of the loop.
For instance: So the questions is how do you get the database table field name by index via code behind?
New Values collection coming from the Grid_Row Updating Event is Empty. Data Table dt = new Data Table(); foreach(Data Control Field Header Cell column in your Gridview. Cells) //Make sure you do all this after your Gridview.Data Bind(); //If you do not want to bind data first simply bind an empty list like so: /* your Gridview.event is raised when a row's Update button is clicked, but before the Grid View control updates the row.This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.
