Control Visibility

Posted on 2008-10-17
Last Modified: 2013-12-17
I have a form with two groups of controls.  On form load group2.visible = false, once the user clicks a button I have group1.visible=false and group2.visible=true.

Well the group1 controls disappear, but group2 controls do not reappear.  What am I doing wrong?

Can't answer that without seeing the code.

I hope this helps.
 private void Form4_Load(object sender, EventArgs e)
            dgvListAnn.Visible = false;
            groupBox6.Visible = false;
private void btnSubmit_Click(object sender, EventArgs e)
            if (expressionBuilder.Rows.Count > 0)
                groupBox5.Visible = false;
                groupBox6.Visible = true;
                dgvListAnn.Visible = true;
                MessageBox.Show("Expression Table is empty. Please add your query.");

I stepped through the debug process and noticed that the app was not chaning the visibility back to true.  Does it have to do with its status in the form.  Once the form is loaded it is set not to be visible, does the form need to be re-loaded?  will I lose the data in the arrays if the form is reloaded?

No you shouldn't have to re-load the form, when your code does the check that the are 1 or more rows does it definately hit these:
                groupBox5.Visible = false;
                groupBox6.Visible = true;

If so it would seem that somewhere in your code you are constantly stating groupBox6.Visible = false;

you are correct.  I found the problem.  To save space on the form, I put controls on top of each other and thought if I hid and unhid I could get around using another form.  But the controls are always hidden beneath another control.  So I used a tabcontrol container in the form.  thanks.
