Asp.net 禁用以编程方式创建的向导控件中的linkbutton

我需要你的帮助。我尝试在向导控件中禁用linkbutton失败

我不能使用javascript，我必须使用userControl

我不想要这种功能性，因为如果我在步骤4中，并且我在步骤1中单击了链接，我的数据不会持久化（每个向导步骤包含不同的UserControl）。如果您认为可以解决此问题，我不需要解决linkbutton问题

我认为我的问题是由于向导造成的，因为我尝试了以下方法： 但它仍然不起作用：(

linkbutton.commandName=null似乎有效。我可以单击，但它不会更改当前向导步骤

这是我的代码：

public class EditOrNew : UserControl
{
    Wizard w = new Wizard();
    WizardStep ws1 = new WizardStep();
    WizardStep ws2 = new WizardStep();
    WizardStep ws3 = new WizardStep();
    WizardStep ws4 = new WizardStep();

    protected override void OnInit(EventArgs e)
    {
        w.ID = "w";                 
        ws1.ID = "ws1";
        ws2.ID = "ws2";
        ws3.ID = "ws3";
        ws4.ID = "ws4";
        ws1.Title = "Select a client";            
        ws1.StepType = WizardStepType.Start;
        ws2.Title = "Select a project";
        ws3.Title = "Select a bot type";
        ws4.Title = "Configure the new task";
        ws4.StepType = WizardStepType.Finish;
    }

    protected override void CreateChildControls()
    {
        this.Controls.Add(w);
        // Allow access to buttonlink in the wizard
        Control ctrl = w.FindControl("SideBarContainer");
        DataList dl = (DataList)ctrl.FindControl("SideBarList");
        foreach (DataListItem item in dl.Items)
        {
            LinkButton b = (LinkButton)item.FindControl("SideBarButton"); 
            b.CommandName = null;  
            // NOT WORK      
            //b.Attributes.Add("disabled", "disabled"); 
            //b.ForeColor = System.Drawing.Color.Pink;                               
            //b.Attributes.CssStyle[HtmlTextWriterStyle.Cursor] = "default";
            //b.Enabled = false;
            //b.OnClientClick = null;
            //b.Attributes.Remove("href");
            //b.Attributes.CssStyle[HtmlTextWriterStyle.Color] = "gray";                
        }
     }

我尝试将允许访问代码放在不同的位置

我不明白为什么commandName可以，而其他的不行

提前感谢。

向导步骤绑定到DataList dl中，因此您可以向dl添加处理程序：

protected override void OnInit(EventArgs e)
{
    w.ID = "w";                 
    ws1.ID = "ws1";
    ws2.ID = "ws2";
    ws3.ID = "ws3";
    ws4.ID = "ws4";
    ws1.Title = "Select a client";            
    ws1.StepType = WizardStepType.Start;
    ws2.Title = "Select a project";
    ws3.Title = "Select a bot type";
    ws4.Title = "Configure the new task";
    ws4.StepType = WizardStepType.Finish;

    DataList dl= (DataList)w.FindControl("SideBarContainer").FindControl("SideBarList");
    dl.ItemDataBound += w_ItemDataBound;
}

void w_ItemDataBound(object sender, DataListItemEventArgs e)
{
    LinkButton lb = e.Item.FindControl("SideBarButton") as LinkButton;
    if (lb != null)
    {
        lb.Enabled = false;
    }
}

这将使侧边栏可见，并突出显示相应步骤的链接，而不可单击。只有按钮可用于导航
