Hi I'm trying to get my comboBox to become visible once a certain item is selected in my listbox.
I have this code:

C#

If(listBox.SelectedItems.Contains("Tea"))
{
    ComboBox.Visible = true;
}

This isn't working... Any other ideas?

And "isn't working" means what exactly? The code is never called? SelectedItems never contains "Tea"? Combobox never becomes visible? The code ran and your hard drive melted?

Hello,
Move the code to click event it will work.

C#

private void listBox1_Click(object sender, EventArgs e)
{
 if (listBox1.SelectedItems.Contains("Tea"))
   comboBox1.Visible = true;
}

Thanks!!!

Sorry... When I run the program, and Tea is selected, the comboBox does not become visible.
However, if I change the code to
If(listBox.Items.Contains("Tea"))
{
ComboBox.visible = true;
}
And I select tea, the comboBox appears. But it appears even if I do not select tea.
