How to stop RowChanging events from firing on fill

Denise

I just realized the DataTable_RowCh anging events were firing when I called
Fill method of the DataAdapter! It fires TWICE for each row loaded. I
thought these were only supposed to be called when data was actually being
edited.

I am using bound textbox controls on the form. Could that have anything to
do with it? Does anyone know how to stop the RowChanging events from
firing?

Thanks!

You can't stop an inherit event like that from firing... you can only "not
handle" it...

Denise,

Not sure why this is happening. I am now assuming that you are doing some
processing in this event that you do not want to happen when the DataAdapter
is being filled. If this is the case then you can handle this in a couple
of ways I can think of:

(1) Define a class level variable call bLoading. Before you call the fill
method set bLoading=True and then set it to False after the fill method. In
the event RowChanging only process if bLoading=False

(2) Do not let VB.NET define the event handler for RowChanging (remove the
handles part of the method declaration) then use a combo of RemoveHandler
and AddHandler before and after the fill method.

How to prevent RowChanging event when filling dataset

by: J | last post by:

I'm experimenting with strongly typed datasets, and when the .Fill method is called, the RowChanging fires for each row. This causes a problem when the existing data does not adhere to the rules outlined in the RowChanging method. Is there an easy way to not have the RowChanging event occur when the dataset is being filled? Example code is daTitleAuthor.Fill(dsAuthors1);

Events fire and then stop firing

by: Randy | last post by:

I have various events on my web form, button clicks, checkboxlist index changes, etc. In the course of testing sometimes they stop working (locally). But then if I double click on them (which me to the code behind view) and simply save the form and run it, they start firing again. I don't have webserver right now and know if this will happen when I deploy to it. Is this a bug in Visual Studio?
