Hi,

I have a usercontrol which contains multiple server controls like
textbox, radiobutton..., I have a public field in the usercontrol
"Enabled". What i want to do is when the usercontrol's "Enabled" is
set to false, set all its child controls "Enabled" to false. I know i
can set them one by one. But there should be a easy way to do it
like :

for(int i=0;i<myUserControl.Controls.Count;i++)
{
control oControl = (control) myUserControl.Controls(i);
oControl.Enabled = false;
}

Anyone can give me a hint?

Sorry, I'm not clear on your question...
...do you mean that the for loop you wrote up there doesn't work ?
If it does, that seems fairly simple to me.. maybe I'd try to save a
line with:

foreach(Control ctrl in this.Controls)
ctrl.Enabled=false;

However, I don't think that the base Control class defines an Enabled
property, and that might be a problem. Then again, a Control might be
a label, a text literal, a generic html control, a bunch of things
were it's not quite clear what it means to be 'enabled' or not. Maybe
when 'enabled' is turned to false on your user control, you just don't
want to display any of its children controls ?
If so, at render time, you could check the value of the user control's
Enabled property:

if(this.Enabled)
base.Render(writer);

HTH,
