I have posted this question 3 times now and no-one has even answered it, so
is it possibly a bug or am i missing something. In short it does not seem to
be possible to set the focus on control from within the Active event handler
of the WizardStep control. Full details below.
For testing purposes i have got a 2 step WizardControl. Eqach step contains
a text box, TextBox1 and TextBox2 respectively. If i put the following code
in the respective activate event handlers for the two steps,
TextBox1.Text ="foo";
and
TextBox2.Text = "bar";
Then in the first step the TextBox (TextBox1) contains the word foo and in
the second step the TextBox (TextBox2) contains the word bar. As you would
expect.
However if i replace the code with
TextBox1.Focus( );
and
TextBox2.Focus( );
Then i get the below error and i can't understand why. This is the
first time i have used Wizard controls and i'm just trying to work out how
they behave. What am i missing about Wizard controls that is causing this
behaviour. Also it does not matter whether the textboxes are within the
wizardstep or not, you cannot seem to set the focus to any control from
within the Active event handler of the WizardStep control. If you call the
focus method from the Page_load event handler then it works fine.
Anyone any idea what is causing this, i have called the focus method from
within other event handlers such as the OnDataBound event and the OnClick
event with no problem.

I suspect it most be something like that, but i was hoping someone might know
at what point the active event for a WizardStep control. I have never had a
problem calling the focus method on a control from any other event.
Could you give me an example of "code to find the parent control" because i
am not sure what you mean by this. Calling focus on any textbox, wherever it
is within the page causes this error.
