E newvalues rowupdating null
I'm trying to extract the oldvalues and assign it into View State. Alok Hi aloksinha83, Please see this post: Qin Dian Tang Microsoft Online Community Support Please remember to mark the replies as answers if they help and unmark them if they provide no help.... For example, for COMPUTING category there will be NOTEBOOKS DESKTOPS etc. I keep getting a "Compiler Error Message: CS0123: No overload for ' Adhoc Job Grid View_Page Index Changed' matches delegate ' System. Getting the control id of a control inside gridview control uhmm.. Do you want's to find particular Textbox with certain id ? I've tried findcontrol and stuff but it is nested inside a user control so I can't figure it out.
However, Command Arguments come from database to linkbutton. I've managed to get the row Index of the row that the user presses inside the Gridview with: Grid View Row row = (Grid View Row) ((Button)sender).
Andwhen one of these command buttons is cliked it must go to proper page.
I would greatly appreciate for any help or suggested ideas/approach in order to accomplish this task, or any sample codes snippet. Null Reference Exception: Object reference not set to an instance of an object...".
What is the proper coding procedures to get the old value from gridview during updating event? I tried the code snippet you've sent but i'm getting an error message: "System.
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).
But you can save the value when you are changing the row into Edit mode, like Datagrid(1.1) to Grid View(2.0) and using the Row Updating event how to extract the values from the controls.
It seems that its not getting the oldvalues and returns a null, which is something strange. If you are not using a 'standard' datasource New/Old Values are not always available in the Row Updating event.
So I figured maybe they have to be two-way databound to access the Old Values collection.
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.
