Gridview edit not updating database
I could then bake in the necessary code by overriding the necessary Grid View methods.To create a custom server control that extends an existing control, create a public class that derives from the Web control that you want to extend.I created a class named method that is called each time a row is added to the Grid View, including the header row.
When I implemented the up and down arrow images for the Data Grid control in Part 18 of the An Extensive Examination of the Data Grid Web Control article series, I put the code that added (or removed) the arrow images in the ASP. Specifically, the code enumerated the Data Grid's properties.
In short, I could have implemented the up and down arrow images in the Grid View using code in the ASP.
In this article we will look at the steps for building such a custom control as well as how to use the control in an ASP. The custom control's complete source code and a demo application are available for download at the end of this article. If you have programmatically bound data to the Grid View, then you will need to create an event handler for the property is toggled.
This functionality enables the Grid View control to provide built-in, bi-directional sorting.
However, if you attempt to update a Grid View's field's properties during the databinding stage, the field reports to the Grid View that its state has been changed and that the data needs to be re-bound.
