Asp net detailsview itemupdating
I figured I would share this little app as I had to play around a bit to get it working.
Notes: I stayed away from stored procedures for simplicity. Dates are handled as strings - handing them correctly is another blog 🙂In my actual app I am using auth - I cut that for simplicity of this blog entry I removed all state managment: user deleting of a row Ok step one is a database - you need to have one 🙂 I used an auto incrementing ID field set as a prmary key - this is used for master\details syncing and image gathering (explored later in this blog). Things of imortance are the ID column (primary auto incrementing field) and the image column (type is Image).
You can customize the user interface of the Details View control to a large extent.
You can choose the most appropriate combination of data fields to render each piece of information conveniently.
Some of the feedback I have received has referenced that the SQL Image type will be depricated (and is in SQL2005). Situations do arise though where it is needed - thus this article.
When the webform is loaded, the gridview control, should retrieve and display all the rows from tbl Employee table.
As soon as I select a row, in the gridview control, then all the columns of the selected row, should be displayed in details view control.
Or, at least, not declaratively and, maybe, not easily.It s fairly common for Web applications to work on a single record at a time.For example, displaying the contents of a single record of data is a necessary practice when you build master/detail views. NET 2.0, the Details View control renders a single record at a time from its associated data source, optionally providing paging buttons to navigate between records and Create/Read/Update/Delete (CRUD) capabilities.I think what you have should work ok, provided the Form View has data and it has been data-bound.Find Control(..) will probably return null if there is no data.
