Rowupdating in gridview in vb net
The Grid View 'Grid View1' fired event Sorting which wasn't handled.
We’ll get to how these properties are populated shortly, but first we need to go back to the Bind Data method.
The original method shown above did not implement any sorting, but now that we have a place to store the Sort Expression and Sort Direction we need to change that.
I have a gridview and a dropdown that appears in my custom edit row ( i added it to the edititemtemplate). The dropdown is in the first columnd and the below is located within : public void rowedit(Object sender, Grid View Edit Event Args e) Drop Down List s = (Drop Down List)Grid View1. I'm giving examples, not typing up your whole app for you. If it doesn't have basic error checking in it, such as object detection or checking if objects are null before using them, put that in there.

The important point is not which of these two events call Bind Data, but one of them must or the Grid View will not be updated. When bound using a Data Source ID, the Grid View internally tracks the current Sort Expression and Sort Direction, and those are available through properties with the same names.
When you manually bind the Grid View, this tracking does not occur, so we must implement some mechanism for tracking those values.
In addition to that, we’re resetting the Edit Index and Selected Index when the page is changed to avoid cases, for example, where you change pages and are suddenly editing a different item.
Bind Data could be called in Page Index Changing, but to show that it the event is raised, we’ve handled that in Page Index Changed.
We also need force databinding to occur when then page is loaded, which we’ll handle in Page_Load.
