catch{} butterfingers {}

[Peter Morris]

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

protected void ArticleFormView _ItemUpdating(o bject sender,
FormViewUpdateE ventArgs e)
{
try
{
//Next line is line 36
if (!ArticleDataSo urce.IsValidNew Values(e.Keys, e.NewValues))
e.Cancel = true;
}
catch (FormatExceptio n)
{
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 ArticleDataSour ce.IsValidNewVa lues 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

Re: catch{} butterfingers {}

First System.FormatEx ception is thrown. Then it appears that this is caught
and thrown as an InnerException of a System.Exceptio n (what a poor choice).

So I have
System.Exceptio n
InnerException = System.FormatEx ception

The ASPX shows the inner exception (FormatExceptio n) so

catch (FormatExceptio n)

will not catch it, I need

catch
{
...etc...
}


Not impressed :-)
