我有一个网络反馈向导，当我在浏览器中测试它时，点击下一个按钮，从第1步到第2步就可以了，但是它拒绝转到第3步。另外，我试图保持焦点在每个步骤的第一个文本框中，但它仍然无法正常工作。当我单击“下一步”时，该步骤会移动（正如我所说的从“联系信息”到“注释”），但它会向上滚动到网页的顶部，并从向导中失去焦点。这很烦人。 所以我有两个问题：（1）我的向导只有四个步骤中的两个。 （2）巫师失去了焦点。
这是我在向导控件中的内容：

这是我在后面的代码中所拥有的：（c＃）
protected void Page_Load(object sender, EventArgs e)
{
//Prevent display of sitemap on default page.
SiteMapNode node = SiteMap.CurrentNode;
if (node.ParentNode == null)
{
SiteMapPath1.Visible = false;
Wizard1.Visible = false;
}
nameLabel.Text = nametxt.Text;
EmailLabel.Text = emailtxt.Text;
cityLabel.Text = citytxt.Text;
stateLabel.Text = statebox.Text;
commentslabel.Text = txtcomments.Text;
ratinglabel.Text = txtrating.Text;
}
public void OnNextButtonClick(object sender, WizardNavigationEventArgs e)
{
this.Wizard1.Focus();
Wizard1_ActiveStepChanged(sender, e);
}
private TextBox FindFirstTextBox(Control c)
{
TextBox nothing = null;
Control results;
if ((c == null))
{
return nothing;
}
if (c.GetType() == typeof(TextBox))
{
return (TextBox)c;
}
foreach (Control child in c.Controls)
{
results = FindFirstTextBox(child);
if (results != null && (results.GetType() == typeof(TextBox)))
{
return (TextBox)results;
}
else
{
return nothing;
}
}
return nothing;
}
protected void Wizard1_ActiveStepChanged(object sender, System.EventArgs e)
{
// Set the focus to the first TextBox in the current step
WizardStepBase currentWizardStep = Wizard1.ActiveStep;
// Find the first TextBox
TextBox firstTextBox = FindFirstTextBox(currentWizardStep);
// If we found a TextBox, set the Focus
if (!(firstTextBox == null))
{
firstTextBox.Focus();
}
}
答案 0 :(得分：2)
好的，那是因为......你在向导的第二步中的txtComments字段上有一个比较验证器...我建议修复它或删除它...这是我所指的代码到（在你的向导第2步中）
<asp:CompareValidator ID="CompareValidator1" runat="server"
ControlToValidate="txtcomments"></asp:CompareValidator>
上述代码中缺少的内容是：
更新您的第二个问题
要专注于每个标签的第一个文本框...并保持滚动位置...请按照以下步骤操作...
第1步在您的Page_Load事件中...添加以下代码行
nametxt.Focus(); // This will make sure that your nametxt texbox has focus when your page loads for the first time
第2步您的FindFirstTextBox方法的代码可以简单如下...所以请将其更新为以下代码...
// This code is pretty much self explanatory
private TextBox FindFirstTextBox(Control c)
{
foreach (Control child in c.Controls)
{
if (child is TextBox)
return (TextBox)child;
}
//If we didn't find a TextBox
return null;
}
第3步将Wizard_ActiveStepChanged事件更新为以下内容...
protected void Wizard1_ActiveStepChanged(object sender, System.EventArgs e)
{
// Set the focus to the first TextBox in the current step
WizardStepBase currentWizardStep = Wizard1.ActiveStep;
// Find the first TextBox
TextBox firstTextBox = FindFirstTextBox(currentWizardStep);
// If we found a TextBox, set the Focus
if (Page.IsPostBack && firstTextBox != null)
{
firstTextBox.Focus();
}
}
在上面的事件代码中，我更改了if语句以对page.IsPostBack进行额外检查...这是因为Focus方法将抛出异常...因为此事件是在OnLoad之前调用的OnRender ......你很想弄清楚为什么这么早就叫这个步骤......
第4步最后，要修复滚动问题...您需要使用更新面板...请参阅下面的代码段...
// Your Update Panel needs a Script Manager to work
<asp:scriptManager runat="server" ID="sm"></asp:scriptManager>
<asp:UpdatePanel runat="server" ID="panel" UpdateMode="Always">
<ContentTemplate>
// ALL YOUR CONTENT MARK UP GOES HERE
</ContentTemplate>
</asp:UpdatePanel>
这应该可以解决你的第二个问题......
