[Solved] EditForm Only Returning SavedValue

[Garry]

I have a fairly simple grid that onyl has 2 columns in it, Key and Value. It is bound to an ArrayList that contains a struct object. Everything thing works as expected, but when I try and get the value from the EditForm it always returns the original value. Not the value that the user has input. I've tried to approach this from a few different examples on the Website, but I have had no luck thus far. Any ideas on how to get the new value? Below is my code.

Thanks!

Hello Garry Clark,

From your code snippets I see that you use simple binding invoking the DataBind() method of the grid. Note that operations like data editing, filtering, etc. require advanced binding through the NeedDataSource event or data source control:

Please modify your code accordingly to avoid the unexpected results. Additional information about how to update grid records you can find here:
