The grid View tracks handlers to ensure something has been added to deal with the update intentionally.
If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.This error occurs when I click the Update button to update a row of record. My first take was that gridview needed on Row Updating but after adding (see markup code), still getting same error. When I click the Update button, I get the aforementioned error. Protected Sub Grid View1_Row Updating(By Val sender As Object, By Val e As Grid View Update Event Args) Dim dd As Drop Down List = Direct Cast(Grid View1.

In one of my projects using the grid this way I am handling "Row Cancelling Edit", "Row Command", "Row Deleting", "Row Editing", "Row Updating" and all the functions are working. Unless you are Manually calling "Add Handler" somewhwere else in code, I don't see a handles claus on your event method that would intercept the event being raised.Can anybody help me pls here is my codes protected void Page_Load(object sender, Event Args e) public object Data Source public string Data Key Names public event Grid Hander Row Deleting; public event Grid Hander Row Sawing; protected void Grid View1_Row Command(object sender, Grid View Command Event Args e) } ublic partial class Category Control Panel : System. Inside the opening gridview tag in the aspx file add the assignment as follows: If the event handler Control Panel_Row Deleting is designed to handle a delete from gridview action then insert this as the event handler name.Ensure that you re-bind the gridview after delete so that the changes are shown on postback.Having a Delete button, or even a regular button in a Grid View with a Command Name of delete, will automatically try to fire On Row Deleting.You can just add it in to make things happy, but don't have it do anything so it doesn't affect the behavior of your delete.
