Handle the paint event
The index of the WinForms StatusBarAdvPanel being painted can be achieved by handling the paint event of the StatusBarAdvPanel.
C#
//Hooks the panel paint event for (int i = 0; i < statusBarAdv1.Panels.Length; i++) statusBarAdv1.Panels[i].Paint += StatusBarPanel_Paint; /// <summary> /// StatusbarAdvPanel paint event /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void StatusBarPanel_Paint(object sender, PaintEventArgs e) { for (int i = 0; i < statusBarAdv1.Panels.Length; i++) { if (statusBarAdv1.Panels[i].Text == (sender as StatusBarAdvPanel).Text) { if (i == 0) this.statusBarAdv1.Panels[0].BackColor = Color.Red; else if (i == 1) this.statusBarAdv1.Panels[1].BackColor = Color.Green; else if(i == 2) this.statusBarAdv1.Panels[2].BackColor = Color.Blue; else if (i == 3) this.statusBarAdv1.Panels[3].BackColor = Color.Orange; MessageBox.Show("Index of the panel being painted is " + i.ToString()); } } }
VB
'Hooks the panel paint event For i As Integer = 0 To statusBarAdv1.Panels.Length - 1 AddHandler statusBarAdv1.Panels(i).Paint, AddressOf StatusBarPanel_Paint Next i ''' <summary> ''' StatusbarAdvPanel paint event ''' </summary> ''' <param name="sender"></param> ''' <param name="e"></param> Private Sub StatusBarPanel_Paint(ByVal sender As Object, ByVal e As PaintEventArgs) For i As Integer = 0 To statusBarAdv1.Panels.Length - 1 If statusBarAdv1.Panels(i).Text = (TryCast(sender, StatusBarAdvPanel)).Text Then If i = 0 Then Me.statusBarAdv1.Panels(0).BackColor = Color.Red ElseIf i = 1 Then Me.statusBarAdv1.Panels(1).BackColor = Color.Green ElseIf i = 2 Then Me.statusBarAdv1.Panels(2).BackColor = Color.Blue ElseIf i = 3 Then Me.statusBarAdv1.Panels(3).BackColor = Color.Orange End If MessageBox.Show("Index of the panel being painted is " & i.ToString()) End If Next i End Sub
