Gridview rowupdating neweditindex

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.

Next, we need to define the database connection string.

The below is my connection string which is stored in web.config file.

Edit Index = -1 'set to no selection Bind Grid View() End Sub One issue I ran into while attempting to figure this all out was if I didn’t rebind my Grid View at the end of each event, I was required to click twice to get it to select the correct row, and if I clicked around, it would always be a row behind. This blog is for nothing else than to try and help me help you and help you help me and us help everyone else try to fix anything and everything we can’t figure out with this language.

Hope this saves someone a full day of research (and possibly some hair)!

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.

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.

NET 2.0 most of the examples and tutorials deal with setting the Data Source ID, which buys you a lot of automation that you may not even appreciate unless you’ve done this the old fashioned way.

In this example, we’ll go through a fully featured Grid View with editing, deleting, selecting, sorting, and paging functionality that is manually bound and identify the limitations and some of the workarounds. Sql Data Source, Object Data Source, Linq Data Source, etc) specified in a Data Source ID, the Grid View can automate many functions because, through the data source control, the Grid View on its own can perform the following operations: When you manually bind data to a Grid View, the Grid View itself cannot perform these operations, so they must be implemented in your code.

  1. UpdatePanel and Gridview. grvEmp. EditIndex = e. NewEditIndex;. protected void grvEmp_RowUpdatingobject sender.

  2. We can see how we can access that in the code behind in the GridView_Rowupdating. NewEditIndex property. So GridView. Row Edit, Delete and Update.
