  1. Adding command bar via designer
  2. Adding command bar via code

To add command bar in C#, follow the given steps:

Step 1 - Add the following required assembly references to the project:

    * Syncfusion.Grid.Base.dll
    * Syncfusion.Grid.Windows.dll
    * Syncfusion.Shared.Base.dll
    * Syncfusion.Shared.Windows.dll
    * Syncfusion.Tools.Base.dll
    * Syncfusion.Tools.Windows.dll
    * Syncfusion.Licensing.dll
    * Syncfusion.SpellChecked.Base.dll

Step 2 - Include the namespace Syncfusion.Windows.Forms.Tools

using Syncfusion.Windows.Forms.Tools;
Imports Syncfusion.Windows.Forms.Tools

Step 3 - Create a CommandBarController instance and set the HostForm property to be the current form.

CommandBarController commandBarController1 = new CommandBarController();

this.commandBarController1.Style = VisualStyle.Office2016Colorful;

this.commandBarController1.HostForm = this;
Dim commandBarController1 As CommandBarController = New CommandBarController()

Me.commandBarController1.Style = VisualStyle.Office2016Colorful

Me.commandBarController1.HostForm = Me;

Adding command bar

Create an instance of CommandBar and add it to the CommandBars collection property of commandbar controller instance. The below code shows a command bar is being added to the commandbar controller.

CommandBar commandBar1 = new CommandBar();

this.commandBar1.Text = "commandBar1";

Dim commandBar1 As CommandBar = New CommandBar()

Child controls

Command bar acts as a container control to host the required control in the tool bar. In this topic the child controls hosted via command bar is discussed.

Adding single control

The controls with single-line visual structure like combo box, text box and button can be added directly to the command bar instance. This can be done via adding the required control via the Controls property of the command bar. In the below code snippet a text box control with key properties defined is being added to the command bar.

Adding multiple controls

In order to host more than one control with better alignment and avoid overlapping, a container control like Panel can be used. In the below code snippet, a combo box is added along with a label control.

Panel panel1 = new Panel();
panel1.Dock = DockStyle.Fill;

Label lable1 = new Label();
lable1.Text = "Combo box text";
lable1.TextAlign = ContentAlignment.MiddleCenter;

ComboBox combobox1 = new ComboBox();
combobox1.Location = new Point(lable1.Width + 5, lable1.Location.Y);
combobox1.Items.AddRange(new string[] { "object1", "object2", "object3", "object4", "object5", });
combobox1.SelectedIndex = 0;

Dim panel1 As New Panel()
panel1.Dock = DockStyle.Fill

Dim lable1 As New Label()
lable1.Text = "Combo box text"
lable1.TextAlign = ContentAlignment.MiddleCenter

Dim combobox1 As New ComboBox()
combobox1.Location = New Point(lable1.Width + 5, lable1.Location.Y)
combobox1.Items.AddRange(New String() { "object1", "object2", "object3", "object4", "object5" })
combobox1.SelectedIndex = 0
