опитвам се да направя метод, който създава списък с името на всички дъщерни контроли на DetalsView, които са от тип string.
Най-близкото до мен беше:
foreach (Control c in dv.Controls)
{
if (c is Label)
{
controlsToCheck.Add(c.ID);
}
}
foreach (string s in controlsToCheck)
{
Label lbl = (Label)dv.FindControl(s);
if (lbl.Text == "")
{
lbl.Text = "None";
lbl.CssClass = "bold";
}
}
Въпреки това всичко, което прави, е да повтори веднъж в първия foreach и след това да излезе (т.е. dv.Controls връща само един елемент). Ако използвам FindControl, мога да стигна до елементите, но това означава, че трябва да го направя за всеки елемент.
Някакви съвети?
Благодаря!
Редактиране: тук е моят DetailsView (изрязах някои неща, които са само с повече контроли, така че да пасват на страницата):
