Default Chapter 15 - Working with Data - Advance Topics

Hello,

In this book version, on page 570, a procedure is defined to hook into a databound asp data control, to change the display based on the data that is being displayed. On page 573 near the bottom it mentions that when using a SqlDataSourceControl, DataItems are presented as DataRowViews, and then go onto explaining how to work with them.

What about when using a EntityDataSourceControl? Is there a sample of doing this exercise using Entities instead?

Thanks,
WebDev123

Hi there,

For an entity data source, you should be able to cast e.Row.DataItem to the type of your entity (like a Genre or a Review) instead of a DataRowView. The remaining code should be more or less the same (except that you now access properties of the object directly.

Hope this helps,

Imar

Default Great info.

Excellent, that's great. That's what I was wondering - what to cast it to. If I can cast directly into an Entity object that's even better, because I can bypass the extra abstract layer of working with the more nebulous DataRowView.

Thanks!
