catch{} butterfingers {}

[Peter Morris]

Hi all, I have a perplexing problem....

protected void ArticleFormView_ItemUpdating(object sender,
FormViewUpdateEventArgs e)
{
try
{
//Next line is line 36
if (!ArticleDataSource.IsValidNewValues(e.Keys, e.NewValues))
e.Cancel = true;
}
catch (FormatException)
{
e.Cancel = true;
Page.Validators.Add(new StaticValidator("Invalid price"));
}
}

As you can see I am catching FormatException. I put a breakline on line 36
and when I hit F10 ArticleDataSource.IsValidNewValues will throw a
FormatException. At this point I would expect my Catch to kick in, but as
you can see from the following exception information it is not. Does anyone
know why this is?


Thanks

Pete

First System.FormatException is thrown. Then it appears that this is caught
and thrown as an InnerException of a System.Exception (what a poor choice).

So I have
System.Exception
InnerException = System.FormatException

The ASPX shows the inner exception (FormatException) so

catch (FormatException)

will not catch it, I need

catch
{
...etc...
}


Not impressed
