How to set property "ReadOnly" on all TextBoxes on a WebForm

Hello,

I'm in the process of learning asp.net and WebForms.

Could somebody indicate how I can write code to control the properties of
the (TextBox) controls on a WebForm.?Thanks.

Use the Page_Load method in your

txtbox1.readonly = True
txtbox2.readonly = True

or depending on the situation you could use;

txtbox1.enabled = False
txtbox2.enabled = False

or

txtbox1.visible = False
txtbox2.visible = False

You can do this in the

Public Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs)
txtbox1.readonly = True
txtbox2.readonly = True
End Sub

Hope this helps,

Thank you both for your reply.

I mean more like a recursive function that can find the TextBox on the Page
and change its property...

You can always use Page.Controls and loop through the controls on the page
and identifying each Textbox object.

But why do want to do this since this is adding extra code to your
application? Please explain what you're trying to do.

I do it all the time. If the result from a dynamic drop down are used
to fill a 2nd dynamic drop down, I will make the 2nd drop down
Enabled=False until the OnSelectedItem change for the first drop down.
Sometimes a sacrifice in a few extra lines of code is necessary for
"ease of use" in your application.

Just my 2 cents.

Thank you all for helping.

I finally used the following:

Private Sub SetTextBoxes(ByVal bval As Boolean)

Dim c As Control

Dim childc As Control

For Each c In Page.Controls

For Each childc In c.Controls

If TypeOf childc Is TextBox Then

Dim t As TextBox = CType(childc, TextBox)

t.ReadOnly = bval

End If

Next

Next

End Sub
