i need to be able to set the readonly property of a textbox at run time. I can see that this property is part of the html. Can you give me an example in vb.net as to how i code this. Thank you...Glee

In your Page_Load() event check the IsPostBack property of the Page object.  If it is false, set the ReadOnly property to true.  The following assumes a TextBox server control named txtTest is on the page.

If Page.IsPostBack = False Then
     txtTest.ReadOnly = False
End If

You should then see the readonly attribute in the <INPUT> element that is rendered as HTML when the page shows in the browser.

Hi there,
if you are using an ASP TextBox (one from the WebForms tab in the ToolBox), just use..
TextBox1.ReadOnly = True/False

if you are using an HTML TextField (one from the HTML tab in the ToolBox), first right click on it and make it "Run At Server",  assign some ID to it, say Text1. Then set the readonly attribute to true/false.
        Text1.Attributes.Add("readonly", "true")

Thank you both for your suggestions. The first one is the one that is appropriate for my situation. The second one may be useful in the future. Glee
