Rowupdating keys

hello my problem was that my gridview editable controls heep their old values. this is due to the grid view binding in the page_load method after every post back.

So what you need to do is store the data source (maybe in Session) and only bind rebind the data when you absolutely need to (Like during the Is Not Post Back) Do you understand?

I'd like to know if there are any other ways to retrieve the new values? I have been using the web site successfully for just over a year, and I am presently using a Select button in the row to launch a detailsview, and I edit the database that way. Net a year and a half ago, and VB programmer forever before that, but I feel pretty confident in this large and powerful website I have created, but the users don't like the details view have expressed a desire to edit on the fly in the gridview. My user base has a hold of management's ear, and my management wants to dump ASP. This could be the straw that broke the camel's back - a person's job hangs in the balance - MINE!! If you are databinding in page_load then you need to only do it if(!

There must be something fundamentally wrong that some of us are doing that is causing this and the fact that it's not happening to others, and they don't know the solution. this only works when the databind happends after the updating. My suggestion to you would be to either subclass gridview, and expose the Extract Row Values though a public method or stick everything you need in Data Keynames. Extract Values From Cell(dict Values, dcfc Cell, gv Row. Row State, True) End If Next control Dim return Values = New Dictionary (Of String, Object )() For Each de As Dictionary Entry In values return Values(CStr(de. Value Next de Return return Values End Function I appreciate your quick and prompt reply, which I looked at from home last night, but was not able to test it until just now, and really the only different was adding the Try Cast. You're trying to extract the values from the edit row right?

Count ----------- The most common problem for losing new data entered while updating a Grid View or Data Grid is that you are resetting the Data Source for the Grid View or Data Grid in the Page_Load method. 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.

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.Hello I have a gridview and tried to use data binding to update the records. I've tried all sorts of things even tried the code below. 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.
