C# - 从母版页重新加载选项卡

发布于 2024-11-14 11:18:49 字数 148 浏览 2 评论 0原文

我的母版页中有一个 FromDate 和 ToDate 文本框以及一个提交按钮。我有 4 个选项卡，其中包含 4 个不同 URL 的链接，显示各种报告。

现在更改日期并单击提交按钮，我可以根据日期更改更新/重新加载报告（选项卡）吗？

预先非常感谢:)

我建议将您的起始日期和提交按钮移至用户控件。然后，您可以将其放在每个报告上，公开并连接控件上已更改的事件，并公开当前日期文本框的属性以弹出到报告中。

在 Visual Studio 中创建一个用户控件。如果您不确定如何执行此操作，请尝试此链接。

使用文本框填充用户控件。像这样的东西：

<div>

<asp:Label ID="FromDateLabel" Text="From:" AssociatedControlID="FromDateTextBox" runat="server" />
<asp:TextBox ID="FromDateTextBox" runat="server" />

<asp:Label ID="ToDateLabel" Text="To:" AssociatedControlID="ToDateTextBox" runat="server" />
<asp:TextBox ID="ToDateTextBox" runat="server" />

<asp:Button ID="UpdateButton" Text="Update" runat="server" 
        onclick="UpdateButton_Click" />

</div>

以及该控件背后的代码。您需要公开一个事件和两个属性，它们可能如下所示：

public partial class ReportDateControl : System.Web.UI.UserControl
{
    public event EventHandler UpdateReport;
    public string FromDate
    {
        get { return this.FromDateTextBox.Text; }
        set { this.FromDateTextBox.Text = value; }
    }
    public string ToDate
    {
        get { return this.ToDateTextBox.Text; }
        set { this.ToDateTextBox.Text = value; }
    }

    protected void UpdateButton_Click(object sender, EventArgs e)
    {
        if (UpdateReport != null)
        {
            UpdateReport(this, EventArgs.Empty);
        }
    }
}

在您的 .aspx 页面中，您需要注册控件，这可能如下所示：

<%@ Register Src="~/Controls/ReportDateControl.ascx" TagPrefix="myapp" TagName="ReportDateControl" %>

然后实际将其放在页面上

<myapp:ReportDateControl id="ReportDateControl" 
                         runat="server" 
                         OnUpdateReport="ReportDateControl_UpdateReport" />

：然后连接后面的代码来处理更新事件：

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void ReportDateControl_UpdateReport(object sender, EventArgs e)
    {
        Controls.ReportDateControl control = (Controls.ReportDateControl)sender;

        string fromDate = control.FromDate;
        string toDate = control.ToDate;

    }
}

在适当的地方更改名称和格式，但这应该会给您一个好主意。

I would suggest moving your from-to dates and submit button to a user control. You can then put that on each report, expose and wire up changed events on your control and expose properties for your from-to date textboxes to pop into your report.

In Visual Studio create a user control. If you are unsure how to do this try this link.

Populate the user control with your text boxes. Something like this:

<div>

<asp:Label ID="FromDateLabel" Text="From:" AssociatedControlID="FromDateTextBox" runat="server" />
<asp:TextBox ID="FromDateTextBox" runat="server" />

<asp:Label ID="ToDateLabel" Text="To:" AssociatedControlID="ToDateTextBox" runat="server" />
<asp:TextBox ID="ToDateTextBox" runat="server" />

<asp:Button ID="UpdateButton" Text="Update" runat="server" 
        onclick="UpdateButton_Click" />

</div>

And the code behind for that control. You'll need to expose an event and the two properties, which might look like this:

public partial class ReportDateControl : System.Web.UI.UserControl
{
    public event EventHandler UpdateReport;
    public string FromDate
    {
        get { return this.FromDateTextBox.Text; }
        set { this.FromDateTextBox.Text = value; }
    }
    public string ToDate
    {
        get { return this.ToDateTextBox.Text; }
        set { this.ToDateTextBox.Text = value; }
    }

    protected void UpdateButton_Click(object sender, EventArgs e)
    {
        if (UpdateReport != null)
        {
            UpdateReport(this, EventArgs.Empty);
        }
    }
}

In your .aspx page you'll need to register the control, which might go something like this:

<%@ Register Src="~/Controls/ReportDateControl.ascx" TagPrefix="myapp" TagName="ReportDateControl" %>

And then actually put it on the page:

<myapp:ReportDateControl id="ReportDateControl" 
                         runat="server" 
                         OnUpdateReport="ReportDateControl_UpdateReport" />

And then wire up the code behind to handle the update events:

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void ReportDateControl_UpdateReport(object sender, EventArgs e)
    {
        Controls.ReportDateControl control = (Controls.ReportDateControl)sender;

        string fromDate = control.FromDate;
        string toDate = control.ToDate;

    }
}

Change the names and formatting where appropriate, but this should give you a good idea.
