Make a control Readonly using the controls Collection

GP
Is it possible to iterate through all the controls collection and make the
textboxes alone as read only.I don't see a readonly property for the
Control.Can some one help me in this context?
I want to do something like this below.But I get a message Readonly is not
valid property.
foreach (Control ctl in pnlBenefits.Con trols)
{
if (ctl is TextBox)
ctl.ReadOnly=fa lse;
}

I believe what you are after is:
..GetType()

why dont you do a explicit typecast and then get its readonly property
foreach (Control ctl in pnlBenefits.Con trols)
{
if (ctl is TextBox)
{
((TextBox)ctl). ReadOnly = false;
}
}

i think this should do the job

Hi Hermit Dave,

Thanks for you response.
This time it didn't error me out, but none of my text boxes is set to
readonly.
My text boxes are declared using System.Web.UI.W ebControls.Text Box,Is it
considered of Type TextBox too while using the Controls iteration.

Thanks

Yeap unless you have another control with the name TextBox it should map to
System.Web.UI.W ebControls.Text Box

Get into Debug mode. put in a break point and see if its getting executed.
also try setting Enabled property to false.

Thanks for your responses.
When I set to readonly it didn't work.Still I am able to edit the controls.
But when I set the control enabled=false.I see the text boxes disabled.
But I want the text box to be read only,so that I can get the values in the
viewstate.
foreach (Control ctl in pnlBenefits.Con trols)
{
s= ctl.GetType().N ame;
if (s == "TextBox")
{
((TextBox)ctl). ReadOnly = false;
}
}
}
Even I tried TextBox txt = (TextBox) ctl;
txt.ReadOnly=fa lse;

Thanks

i think it could be based on rendering of the textbox. at the end of the day
its the browser that acts on the html attribute in the element and makes it
readonly.
with enabled = false i think you cannot do anything with the instance. ie no
modifications cant even get the focus. you still have access to the object
and the viewstate etc from serverside. The enabled = false is only for
client side rendering.

foreach (TextBox tb in pnlBenefits.Con trols)
