Hi, I am using server controls (textbox, dropdownlist, calendar)
inside of a form view, it seems that the .Net framework (VB.Net & Net
Frame Work 2.0) makes it difficult to access the control properties
when embedded inside of a FormView control.

What I am trying to do is to enable or disable a textbox control
programatically by accessing the property of the control, along the
lines of:

                                      textbox1.Enable = false

However, when the textbox control is embedded in a Formview nested in
the EditItemTemplate then the textbox is Not accessible.  I would
think that the following syntax should work, but it does not:

 
FormView1.EditItemTemplate.Textbox1.Enable = false


Could anyone suggest the proper syntax for me to Get/Set the
properties of controls embedded inside of a formview while using
VB.Net & .Net Frame Work 2.0?

Use FindControl:

CType(FormView1.FindControl("TextBox1"),TextBox).Enabled = false;

Update:

I am able to "Get" (read) the value - see sample code below, the <
MsgBox(tb.Text) > does retrieves the text value, however the following
SET argument < tb.Enabled = False > does not seem to take effect on
the control, since after the Sub is executed the textbox control
remains enabled - Any thoughts on this side effect?  I would think I
should be able to "Set" the properties of the control, right?

Thanks in advanced,

Riki, thanks for the feedback, I tried your suggestion, and it seems
that I am able to read (Get) the text value from the control without
problem, however, I am not able to "SET" the Enable = False, thus the
control remains editable.  Could you suggest a solution with regards
to why the SET function is not working? (see code snip below)

Thanks in advanced,
