The following example provides sample implementation of the CommandPanelBase class. It uses the base constructor to assign the ControlPanel control to which the ToolBoxPanel is connected. In the button event it calls the ControlPanel control and changes its mode so that controls corresponding to it could be rendered (See ControlPanelBase class for more information)

public class ToolBoxPanel : CommandPanelBase {    public ToolBoxPanel(ControlPanel panel)        : base(panel)    {    }    protected override void CreateChildControls()    {        this.Controls.Clear();        HtmlGenericControl p = new HtmlGenericControl("p");        HtmlGenericControl strong = new HtmlGenericControl("strong");        strong.InnerText = "Select mode:";        p.Controls.Add(strong);        this.Controls.Add(p);        HtmlGenericControl div = new HtmlGenericControl("div");        LinkButton btnCategory = new LinkButton();        btnCategory.ID = "btnCategory";        btnCategory.Text = Messages.ViewCategories;        btnCategory.Style.Add("display", "block");        div.Controls.Add(btnCategory);        LinkButton btnType = new LinkButton();        btnType.ID = "btnType";        btnType.Text = Messages.ViewTypes;        btnType.Style.Add("display", "block");        div.Controls.Add(btnType);        this.Controls.Add(div);        btnCategory.CommandName = "ShowCategories";        btnCategory.Command += new CommandEventHandler(Button_Command);        btnType.CommandName = "ShowTypes";        btnType.Command += new CommandEventHandler(Button_Command);    }    void Button_Command(object sender, CommandEventArgs e)    {        switch (e.CommandName)        {            case "ShowCategories":                //Set the mode in the ControlPanel to display the job category data.                ((ControlPanel)base.ControlPanel).SetMode(DisplayMode.CategoriesList);                break;            case "ShowTypes":                //Set the mode in the ControlPanel to display the job type data.                ((ControlPanel)base.ControlPanel).SetMode(DisplayMode.TypesList);                break;        }    } }
