Rowupdating e newvalues
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.
This will lead to problems like "Grid View does not show updated values", "Grid View looses values changed by user". In your Page_load, this is typically only inside a block where you check to make sure that Page_Load is not being called during a post-back call.
I am just wondering how to access the cell value for the row updating (event = Gridview.
PS: location name is not an integer You don't access the table cells by name. So, basically, instead of looking for table cells, look for the appropriate e. New Values Hi mckrecker, thanks for your reply but I dont need to differ between old and new values since I set a datakey which is the unique ID in my db and I update where unique ID = @unique IDselected of column.
New Values -- it will have all the values, as does e. There are two in that event so data source controls can differnitate bewteen the two.
But for this demo, I’ll show you the simple version, that also doesn’t work 🙂Let’s bind the data to our Grid View and have it autogenerate our columns, as well as an edit button.
When we edit a row in our Grid View and press the “Update” button, at some time it’s received in the Row Updating method.
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).
Row Updating event, doesn’t work as all samples say it should do.
All samples of course assume you’re doing everything in your page, but I have to do everything in my code-behind, because on forehand I don’t know what I’ll be binding to my Grid View.
In my case this was happening because I was binding to a List of custom objects.
Note A common mistake that a lot of people do is that they perform a databind each and every-time the Page_Load method is called.

To String Message="Conversion from string "Location Name" to type 'Integer' is not valid." I would prefer to get the cells by name rather then by location e.g. Keys is an array of all the data keys you define for the gridview (Data Key Names="id", where "id" is the field name from your database query) e. Old Values are arrays of all the fields in the gridview data source that are NOT leys, where, as you might guess, e.
