Body
An ADO.Net Dataset uses Optimistic Concurrency by default. If an attempt is made to update a row to the database when the row no longer exists in the database then the result is the error: Concurrency violation: the UpdateCommand affected 0 of the expected 1 records. Here is the scenario where that error can occur. <pre><code>// data row has been added DataRow dr= null; dtTab = (DataTable)Session("dtTab"); dr = dtTab.Rows(e.RowIndex); dr.Delete(); dtTab.AcceptChanges(); // If Acceptchanges() being not called, row status will be //detached, that will not be updated to database. //Without updating database Acceptchanges() called.Row status //changed to deleted. If this update to database, // it will give concurrency error- // because row no longer exist in database. </code></pre> The reason for the error became apparent. The records in the row in the table didn't exist in the database. However, the DeleteCommand was trying to remove them from the Database. And when the data adapter class attempts to delete a record and doesn't see any rows being changed, it assumes that a concurrency violation has occured. <blockquote> Here is the <a href="http://www.c-sharpcorner.com/uploadfile/cf9547/error-system-data-dbconcurrencyexception-concurrency-violation-the-updatecommand-affected-0-of-th/" rel="nofollow">artcile</a> (The Source of above code) regarding the issue. This article describe when the DBConcurrencyException will raised and how to solve the problem. Please go through the artcicle. Please try the same things with store procedure, may this will help you. </blockquote>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
