Gridview rowupdating e keys
We can achieve the same functionality using Datakeys. In this example, I am going to retrieve values from categories table of Northwind database. Drag a Grid View into the Web Form and assign Data Key Names property with the primary key column i.e. In the gdview_Row Editing and gdview_Row Deleting event, we have used the below code to retrieve categoryid from datakey of Grid View, int catid = int. I just tested that Protected Sub Wr_Updated(By Val sender As Object, By Val e As System. how strange, the same thing worked perfectly on a different site: the sql part works... Row Updating Dim select Row As Grid View Row = Grid View Wn. Update() End Sub one of my other fields does not work either. A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source. A datakey represents the primary key field or field of a record that can uniquely identify it in a data-bound control. Row Index represents the index of the particular row.
hello my problem was that my gridview editable controls heep their old values. this is due to the grid view binding in the page_load method after every post back. event is raised when a row's Update button is clicked, but before the Grid View control updates the row.This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs. New Values("Location ID"); ok the the update worked when I assign a mock value.. Text could not avoid the cell numbering :/ somehow select Row.
