Gridview rowupdating not retrieving newvalues
I ran into a situation this morning where the Row Updating event of a Grid View kept insisting there were no entries in either the Old Values or New Values dictionaries. not-for-mail | Xref: TK2MSFTNGXA02gbl microsoft.public.dotnet.framework.aspnet:372150 | X-Tomcat-NG: microsoft.public.dotnet.framework.aspnet | | I ran into a situation this morning where the Row Updating event of a Grid View kept insisting there were no entries in either the | Old Values or New Values dictionaries.

The Grid View is bound to a strongly-typed collection, derived from Collection Base, through the control's datasource property at runtime.

I don't recall seeing it emphasized in the documentation, and these kinds of dependencies create annoying bugs.
Hi there, I have the same problem and I checked the e.
New Values,this is equal to Nothing, I Bind it to List object.
I need to get at the underlying data value in the data source.
i am getting old values in the rowupdation in gridview , while clicking over the update button , in my code behind i am using below code to get value. Find Control("txtunit_price") 'Reset the edit index. To get both the old and the new value of a field named unit_price, (for the example as a String.
Find Control("txtdescription") Dim txtunit_price As Text Box = gvr. Edit Index = -1 'Bind data to the Grid View control. When all you've got is a Hammer, Every Problem looks like a Nail. Since you are already getting a Row Updating event, I'll work from there.

I am using a SQLData Source to populate my gridview in ASP. When I hit Edit, the textboxes appear and I am able to edit my values. I am using a SQLData Source to populate my gridview in ASP. When I hit Edit, the textboxes appear and I am able to edit my values. In the Row Editing function, the edit textboxes appear and I can get the "old" values Then the page renders, I edit the textboxes and hit Update.
When I hit Update, the changes are not saved, and there is no error message. When I hit Update, the changes are not saved, and there is no error message. Then the page posts back, the text boxes go back to being labels and the new values are lost, and the Row Updating code never fires. Yes, I did put the breakpoint at the Row Updating line (and not in the function).
