Question

我的.aspx webform中有一些包含一些数据的表单

我也有一个按钮。当我点击该按钮时，我需要加载另一个完全相同的表单，但不刷新网站，所以我不会丢失上一个表单中的任何数据。

我该怎么做？

<form id="form1" runat="server">
    <asp:Label ID="labelOpis" runat="server" Text="Opis izdelka"></asp:Label><br />
    <asp:TextBox ID="inputTextArea" class="form-control" runat="server"></asp:TextBox><br />
    <span style="color:red"><asp:Label ID="errorOpis" runat="server"></asp:Label></span><br />
    <asp:Label ID="labelKolicina" runat="server" Text="Količina"></asp:Label><br />
<asp:TextBox ID="inputKolicina" type="number" class="form-control" runat="server"></asp:TextBox><br />

<button id="btnAddNewProduct" class="form-control">Add new product</button>

Answer 1

我认为您正在寻找动态添加的User Controls。

向项目添加新的用户控件并将表单放入其中。

<asp:Label ID="labelOpis" runat="server" Text="Opis izdelka"></asp:Label>
<br />
<asp:TextBox ID="inputTextArea" class="form-control" runat="server"></asp:TextBox>
<br />
<span style="color: red"><asp:Label ID="errorOpis" runat="server"></asp:Label></span>
<br />
<asp:Label ID="labelKolicina" runat="server" Text="Količina"></asp:Label>
<br />
<asp:TextBox ID="inputKolicina" type="number" class="form-control" runat="server"></asp:TextBox>
<br />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

在包含控件的页面上，您需要添加PlaceHolder

<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
<br />
<asp:Button ID="AddControl" runat="server" Text="Button" OnClick="AddControl_Click" />

然后，您需要（重新）在每个页面加载上创建用户控件，然后单击添加控件按钮。

protected void Page_Load(object sender, EventArgs e)
{
    //check if the viewstate exists and if so, build the controls
    if (ViewState["controlCount"] != null)
    {
        addControls(Convert.ToInt32(ViewState["controlCount"]));
    }
    else
    {
        //if not add just 1 control
        addControls(1);
    }
}

private void addControls(int n)
{
    //loop the amount of controls and add them to the placeholder
    for (int i = 0; i < n; i++)
    {
        UserControl1 control = (UserControl1)LoadControl("~/UserControl1.ascx");
        PlaceHolder1.Controls.Add(control);
    }

    //save the control count into a viewstate
    ViewState["controlCount"] = PlaceHolder1.Controls.Count;
}

protected void AddControl_Click(object sender, EventArgs e)
{
    //add an extra control
    addControls(1);
}

<强>更新

您可以通过使用getter和setter在User Control中设置属性来访问TextBox的值。

public string textBox1
{
    get
    {
        return TextBox1.Text;
    }
    set
    {
        TextBox1.Text = value;
    }
}
protected void Page_Load(object sender, EventArgs e)
{
}

现在您可以通过循环所有控件并获取值来从Parent访问它们。

foreach (UserControl1 control in PlaceHolder1.Controls)
{
    Label1.Text += control.textBox1 + "<br>";
}

在

中添加代码

<asp:updatepanel>

标记并向您添加onclick属性按钮。之后，您可以在代码后面编写业务代码（aspx.cs）。这是asp.net中的默认ajax

如何在点击时加载/显示asp.net表单（面板）
