im trying to make a method that creates a List with the name of all the child controls of a DetalsView that are of type string.
The closest i got was:
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";
}
}
However, all this does is iterate once in the first foreach, and then exit (ie. dv.Controls only returns one item). If i use FindControl, i can get to the items, but it means i have to do it for each item.
Any toughts?
Thanks!
Edit: here is my DetailsView (i cut some things out, which where just more controls so it fits on the page):
