Gridview rowupdating newvalues count 0
Without seeing your markup, it's hard for me to tell if you've created .Although this isn't as big of a problem when you're referencing the text from web controls, getting in the habit now will prevent you from serious headaches and inefficiently checking for null and empty later. NET 4.0, you should have access to event, you need to pull the new values out of the front-end controls, and then re-bind your data.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. Please post the code for your Page_Load method and the that handles your Update (your C# code) so we can have a better look at what's going on. Please give some references and/or details of how to. This wipes out the data provided by the user during editing (editing happens after the page load). If you reset the Data Source at this stage, your values for updating will be lost. I actually don't know how to write the Row Updating function, I just found it from the internet, and so of course it's not working. Please give some references and/or details of how to. Ok what's happening is that you are binding the data source for the Grid View every time a postback occurs in the Page_Load method.
I have a Grid View control and use old style manual binding with a Data Source property and invoke the Data Bind() method.
Check out what I’m trying to do, maybe you can help?
First, I load up some data: After that, I’m doing some work to make my Grid View look beautifull, adding all columns by hand.
But as I noted in the comments in that method, some collections that should contain the columns (names, old values and new values) are always empty. And the Row Updated method is never even touched!!! NET Forums that I need to use a Data Source control.
For example a Sql Data Source, which is automatically added to your Web Form if you drag-n-drop your way around Visual Studio 2005.
