By default, the TabControl doesn't support the close button, to create TabControl with the close button, you can modify your code as shown below.
Creating a new Windows Forms Application project, then open your form designer.
How to Add a close button to Tabs in TabControl c#
Drag and drop the TabControl control from your Visual Studio Toolbox to your form designer.
Right-clicking on the TabControl, then select Properties.
Next, you need to set the DrawMode of your TabControl to OwnerDrawFixed.
Opening your code behind, then declare as shown below.
Point _imageLocation = new Point(20, 4); Point _imgHitArea = new Point(20, 4); Image closeImage;
Right-clicking on your project, then select Properties => Resources. Next, Copy a close button image (16x16) into the Resources tab.
Adding a Form_Load event handler to your form allows you to initialize a close button with TabControl.
private void Form1_Load(object sender, EventArgs e) { closeImage = Properties.Resources.close; tabControl1.Padding = new Point(20, 4); }
Adding a Draw_Item event handler to the TabControl allows you to draw image close button to the TabPages.
// c# close button tab control private void tabControl1_DrawItem(object sender, DrawItemEventArgs e) { Image img = new Bitmap(closeImage); Rectangle r = e.Bounds; r = this.tabControl1.GetTabRect(e.Index); r.Offset(2, 2); Brush TitleBrush = new SolidBrush(Color.Black); Font f = this.Font; string title = this.tabControl1.TabPages[e.Index].Text; e.Graphics.DrawString(title, f, TitleBrush, new PointF(r.X, r.Y)); e.Graphics.DrawImage(img, new Point(r.X + (this.tabControl1.GetTabRect(e.Index).Width - _imageLocation.X), _imageLocation.Y)); }
Adding a Mouse_Click event handler to the TabControl allows you to remove TabPage.
private void tabControl1_MouseClick(object sender, MouseEventArgs e) { TabControl tabControl = (TabControl)sender; Point p = e.Location; int _tabWidth = 0; _tabWidth = this.tabControl1.GetTabRect(tabControl.SelectedIndex).Width - (_imgHitArea.X); Rectangle r = this.tabControl1.GetTabRect(tabControl.SelectedIndex); r.Offset(_tabWidth, _imgHitArea.Y); r.Width = 16; r.Height = 16; if (tabControl1.SelectedIndex >= 1) { if (r.Contains(p)) { TabPage tabPage = (TabPage)tabControl.TabPages[tabControl.SelectedIndex]; tabControl.TabPages.Remove(tabPage); } } }
Through this c# example, i hope so you can easily create c# close tabs for TabControl.
