C rowupdating cancel
In this Article you can learn how to edit, update, delete, and cancel in gridview.First drag and drop Gridview from the toolbox to page.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.1) Add Html markup i.e (Gridview) 2) On Page load bind Gridview control. Finally, to pull your hidden value that you’ve dubbed a Data Key in the Grid View’s subroutine. Remember that my first column was a Hyper Link Field, so in order to pull that value, I must cast that column as a Hyper Link.
With a little bit of research, a lot bit of patience, and some help from the internet community, I was able to solve all my issues, and pretty elegantly at that. You can’t do something like Dim name As Hyper Link Dim inv As Text Box name = CType(Grid View1. in an actual post, just email me or comment somewhere and we’ll talk about it.
I suppose my eyes got big when I saw all the new properties and methods, and wanted to try them all out. Most articles I found were for hardcoded datasources (especially on MSDN, ugh) and didn’t really help me much, so this post will be referring to Grid Views with dynamically bound datasources.
First, create a Grid View with three bound columns and an Update/Edit/Cancel (Command Field) column: Nothing in there should be shocking to anyone: all your events are handled, you have a Hyper Link Field that uses the Data Navigate URLFields property to insert a Product ID, and you have set your Data Key Names property to your hidden field which holds your Product ID.
This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.
A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.
The following example implements a custom defined toolbar with ASPx Buttons, which perform all the editing capabilities over a grid's data source.
