two ways to find a label control in a gridview and set its text property.
Which is the perfered way I perfer the first one, but i'm new to cs.

if (e.Row.RowType == DataControlRowT ype.DataRow)

// type 1 is more "C" Like
if (((GridViewRow) e.Row).FindCont rol("lbl_One1") != null)
((Label)((GridV iewRow)e.Row).F indControl("lbl _One1")).Text =
"YES!";
// type 2 more VB like
if (((GridViewRow) e.Row).FindCont rol("lbl_One1") != null)
{
Label lbl =
(Label)((GridVi ewRow)e.Row).Fi ndControl("lbl_ Two2");
lbl.Text = "AND Yes!";

Hi,
Maybe I got lost in so many () , but what is the difference between both
variants?
They look the same to me, just that in the 2dn version you use a temp
variable.

that is the idea, they do the samething, but are they samething? Are they
both way too complicated?, how would you do it?
Also, is one way safer or better?
given that i created a temp variable in the second does this use more
memory, albeit verry little more, than the first because it's creating a
temp; Or is the temp created anyway by using the cast because CLR just does
it that way?
It's not C++ so i'm trying to learn what's best for this langage.

I think it comes down to personal preference, and I don't believe that
either method is appreciably more efficient than the other...
I have a personal preference for the first option...
I'm sure that other people would say that the second option is more
readable...

Appreciate your response (from both of you). Upon a little work i discovered
that i can do the same thing in vb.net but this style is frowned upon for
it's wordiness
consider: C# (please ignore the lack of error checking)
((TextBox)((ASP .master_mp2_mas ter)Master).Fin dControl("TextB ox1")).Text =
"YES";
vs VB
DirectCast(Dire ctCast(Master,
ASP.master_mp2_ master).FindCon trol("TextBox1" ), TextBox).Text = "YES"
Most would break this up into steps, where as i would not unless i had to.
My concern is that my statements are getting too wordy, they are not too for
me because i did C and C++ 15 years ago, but this is C# not C++ and i want to
learn good coding practices.
Thanks!!! (I owe you both a favor)

Hi,
No offense, but not only is that stuff unreadable, but it is also very
inefficient. How about :
// The label to show <insert comment>
Label label = (e.Row as GridViewRow).Fi ndControl (LABEL_BLOB) as Label;
// The label was not found, we are therefore showing a non-BLOB page
if (label != null)
{
label.Text = "Yes";
}
I would also see if the first line could be improved by looking at the
details of how it is setup etc, but for now, this would be a good start.

followup: How is it inefficient?
if i read it correctly my way is way less readable, no question, but it's
not creating an object for compairson or assignment. I'm not saying you're
wrong at all, just would like it explained.
Your answer was very appreciated!

1. "Y as X" is cheaper than "(X) Y"
2. FindControl is (sometimes) called twice instead of once. That's
significant.
