我需要你的帮助。我尝试在Wizard控件中禁用链接按钮失败。
我无法使用javascript,我必须使用userControl。
我不想要这个功能,因为如果我在步骤4中并且单击步骤1的链接,则我的数据不会持久存在(每个wizardStep包含不同的UserControl)。如果您认为可以解决此问题,我不需要解决链接按钮问题。
我认为我的问题是由于向导,因为我试试这个: Disable linkbutton programmatically 它仍然不起作用:(
linkbutton.commandName = null似乎有效。我可以点击但它不会改变当前的wizardStep。
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到不同的位置。
我不明白为什么commandName没有问题而其余部分没有。
提前致谢。

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,链接突出显示到相应的步骤而不是可点击的。只有按钮可用于导航。
