Hi there, I hava a Form with 2 UserControls and 1 dialogBox. I want to use the DialogBox to set which UserControl will display on the Form. -UserControlA(a button: buttonToB) Form -UserControlB(a button: buttonToA) -DialogBox(2 buttons: Ok & Cancel) The Form will display UserControlA as StartUp, when buttonToB is clicked, the DialogBox appears, if Ok is pressed, then UserControlA will be removed and UserControlB will be add to the Form. I have public menthods in the Form as follows: public void RemoveUserControlA(){ this.Controls.Remove(UserControlA) // remove B UserControlA.Dispose(); } public void AddUserControlB(){ this.Controls.Add(UserControlB) } In the UserControlA, when the buttonToB is clicked private void buttonToB_click(){ if(dialog.Result == Ok){ Form f = new Form(); f.RemoveUserContorlA(); f.AddUserControlB(); } } Questions 1) How can I have some methods in the Form, and then invoke it in the UserContolA (i.e. public methods ?)? 2) How can I remove the Usercontrols using the dialog? thanks. :)

:omg:I have a Form with a ListView and two buttons(Move_Up & Move_Down). I want to reoder the ListView by moving an item up or down by clicking either the button Up / button Down. I get the selected listView item's Index, then use Index + 1 or Index -1 to move the item up / down. The code of move up with Index-1 works. But the code of move down with Index+1 does not work. I don't know why, please help! Thanks! The code is as follows: // this move up works (Index-1) private void btnUp_Click(object sender, System.EventArgs e){ if(listView1.Items.Count != 0){ ListViewItem item = listView1.FocusedItem; if(item != null){ int index = item.Index -1 ListViewItem insert = (ListViewItem) listView1.Items.Insert(index, insert); listView1.Items.Remove(item); } } } // this move down does NOT work (Index +1) private void btnDown_Click(object sender, System.EventArgs e){ if(listView1.Items.Count != 0){ ListViewItem item = listView1.FocusedItem; if(item != null){ int index = item.Index + 1 ListViewItem insert = (ListViewItem) listView1.Items.Insert(index, insert); listView1.Items.Remove(item); } } }
