Loop through all text boxes a column in a grid

[staeri]

I have a GridView which dynamically creates text boxes. It could be
between 1 and 100 textboxes depending on how many records there are in
the database.

I need to loop through all the text boxes and to calculate a sum of all
of them which I put into a label in the grid.

I give the text box the name "txtAmount" but the GridView renames each
text box so I never really know the final name.

I'm very grateful for help!

Regards,

Staeri

You don't have to reference the text boxes by name; you could simply
reference them by form element. Every form has an array, which keeps
track of its form elements, and references them starting at 0. For
example, if you have a text box, a radio button, and a pull-down menu,
in that order, you could reference them as formelement[0],
formelement[1], and formelement[2], respectively. Just make sure you
get the references right; if you don't, and you (say) try to parse a
radio button thinking it is a text box, you will get errors.

You would keep track of the size of the array with the length feature.

View the source code on the following page; it shows an example of
referencing the form elements, but the form itself is static (so the
length feature doesn't have to be used):

The `elements' property refers to an HTMLCollection object, not to an
Array object.
