Find All Labels On Form

[Guest]

I am trying to write some code which will find all of the "Label" controls on
the form and change some property.

I started off by iterating over the Page.Controls and looking the the type
of each control to see if it is a label. This does not do the trick. I am
guessing that if a control contains other controls, I am not seeing them. Is
there a property which tells me if the control has other controls within in
it? Would I then itterate thought the collection of controls of that control
looking for labels and controls which contain other controls?

Thanks in advance for your assistance.

You would have to write a little recursive routine that would go through
each controls collection of every control and look for Labels, and then do
something.

The control has a HasControls method. And yes, the Controls collection
contains only the direct children so you would have to iterate
recursively to find Labels (or whatever) at deeper levels.

Sample Code:

private void ChangeControlProperties(Control oParent)
{
int iItem;
Control oChild;
Label oChildLabel;

if ((oParent == null) || (!oParent.HasControls()))
{
return;
}

for (iItem = 0; iItem < oParent.Controls.Count; iItem++)
{
oChild = oParent.Controls[iItem];
if (!oChild.Visible)
{
continue;
}

if (oChildLabel is Label)
{
oChildLabel = (Label) oChild;
// Change Label Properties Here
}

ChangeControlProperties(oChild);
}
}

Call it as following:
ChangeControlProperties(Page);
