Rowupdating gridview newvalues empty

The database table used here has just two fields (sid and sname) My code is as follows: Web Page: --------------------------------------------------------------------------------------------------- im having the same problem i think: in my case i have set binding for template fields; ive a grid with 2 types of field: - bound filed editable (no the tamplate) - bound readonly field (template field) ive set Eval for the template and it is readonly, i placed also Bind to make a test but still count is zero; also had a try changing the datasource, and sure i have set the key field for the grid. OK, so I solved my problem, but not straight forward.

I am having a similar problem, but I don't have any Edit Item Template items in my grid. I just changed my code to use an Object Data Source.

Take a look at the page load if you are binding on post back then the values get updated before you are able to access them.

Please help me with writing a Row Updating function in C#, I don't know how to grab the current field's value and also get the old value for one of keys (which is Project Name for editing) of the selected row. the idea wa to don't allow binding the grid view after a post back.

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.

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...".

Two things: | | 1) I think this needs to be documented better.

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?
