Question

        private void userToolStripMenuItem_Click(object sender, EventArgs e)
        {
            frUser user = new frUser();
            user.Show();
        }


        private void categoryToolStripMenuItem_Click(object sender, EventArgs e)
        {
            frCategory category = new frCategory();
            category.Show();
                

hi, why i can open user form using this code yet cannot do for category?
when i put 'category.' the suggestion didnt show up 'Show' and when i manually do this, the code is not being recognized by vs.

this is a code at a main form to open subform using tool stripbar.

thank you

Probably frCategory is not a form. Maybe it is a User Control or something else.

What do you see if you select frCategory and press <F12> (which is “Go to definition”)?
