Sqldataadapter rowupdating event

I'm trying to validate data before they are updated to the database by handling the Row Updating event for a Sql Data Adapter. Get Child Rows(relation) will always return nothing rows = e. Get Child Rows(relation) Next If you try this code, e. Get Child Rows(relation) will always return nothing even though the Data Table which contains the Data Row has Data Relation.

The data being handled has Data Relation which is related to another Data Table.

Since this event is not well suited to client-side data-validation, what is a good (best practices) use of the event?

You can use Row Updating to modify update behavior before it happens, to provide additional handling when an update will occur, to retain a reference to an updated row, to cancel the current update and schedule it for a batch process to be processed later, and so on.

Update(r Data Set, "Table") ' remove handlers Remove Handler r Adapter.

Row Updating, Address Of On Row Updating Remove Handler r Adapter.

Row Updating, Address Of On Row Updating Remove Handler this Adapter.

Row Updated, Address Of On Row Updated Catch ex As Sql Exception Console. Message) Finally ' Close Connection this Connection.

The original idea to use Data Table instead of Data Set is because in my opinion, sending the Data Table will be faster than Data Set, but it seems to produce more problem than I have ever thought of.

Good that you answered your question, but I think crossposting rarely helps you get the answer your looking for (except when the issue lies on teh seam between multiple groups).

I wrote a code which look something like this, Dim relation As Data Relation For Each relation In e.

microsoft.public.dotnet.framework,microsoft.public .dotnet.framework.adonet,m icrosoft.public.dotnet.framework.webservices,micro soft.public.dotnet.general ,microsoft.public.dotnet.Whenever making crossposts, please use *only* the appropriate groups. As for that, I also need to retrieve the Data Relation from the current row being updated.

code to set up the data adapter // add the event handlers da.

Row Updating = new Sql Row Updating Event Handler(da_Row Updating); da.
