如何选择在另一个页面中选择的相同选项

本文关键字：选择 选项 另一个 何选择 | 更新日期: 2023-09-27 18:03:59

我有几个下拉列表在我的主页:

<asp:DropDownList style="width: 245px;" class="default" ID="slcLocation" runat="server" ClientIDMode="Static" AppendDataBoundItems="true">
</asp:DropDownList>
<br /><br />
<asp:DropDownList style="width: 245px;" class="default" ID="slcSpecialty" runat="server" ClientIDMode="Static" AppendDataBoundItems="true">
</asp:DropDownList>
<br /><br />
<asp:DropDownList style="width: 245px;" class="default" ID="slcGender" runat="server" ClientIDMode="Static" AppendDataBoundItems="true">
    <asp:ListItem Text="Any Gender" Value="" Selected="True" />
    <asp:ListItem Text="Male" Value="1" />
    <asp:ListItem Text="Female" Value="2" />
</asp:DropDownList>
<asp:Button ID="btnGoAll" class="loginButton" style="padding: 10px; float: right;" Text="Search All" OnClick="btnGoAll_Click" runat="server" ClientIDMode="Static" />

前两个是从后面的代码自动填充的，而最后一个是在我的aspx页面中填充的。生成页面后，源代码如下所示:

<select name="ctl00$FeaturedContent$slcLocation" id="slcLocation" class="default" style="width: 245px;">

<select name="ctl00$FeaturedContent$slcGender" id="slcGender" class="default" style="width: 245px;">
    <option selected="selected" value="">Any Gender</option>
    <option value="1">Male</option>
    <option value="2">Female</option>
</select>
<input type="submit" name="ctl00$FeaturedContent$btnGoAll" value="Search All" id="btnGoAll" class="loginButton" style="padding: 10px; float: right;" />

我有一个按钮点击选项在我的主页像这样保存变量在一个会话:

protected void btnGoAll_Click(object sender, EventArgs e) {
        var locText = slcLocation.SelectedItem.Text;
        var speText = slcLocation.SelectedItem.Text;
        var genText = slcGender.SelectedItem.Text;
        Session["LocationText"] = locText;
        Session["SpecialtyText"] = speText;
        Session["GenderText"] = genText;
        Response.Redirect("~/physicians.aspx", false);
    }

我在另一个页面(physician.aspx)中有相同的ASPX代码，它显示相同的下拉列表。我想要的是，当用户从主页单击提交按钮时，下拉列表将自动填充physician.aspx页面中的这些选择。

我在physician.asp页有这样的东西:

public partial class physicians : System.Web.UI.Page {
    string cString = "";
    SqlConnection Conn;
    string strQueryAll = "*";
    string sqlCode = "";
    string theLocation = "", theSpecialty = "", theGender = "";
    string locVal = "", speVal = "", genVal = "";
    string lVal = "", sVal = "", gVal = "";
    int rowCount = 0;
    protected void Page_Load(object sender, EventArgs e) {
        if (!Page.IsPostBack) {
            PopulatePhysician();
            ASPopulateLocation();
            ASPopulateSpecialty();
        }
        if (Session["LocationText"] != null && Session["SpecialtyText"] != null && Session["GenderText"] != null) {
            //dlo.InnerHtml = "Successfully retrieved " + (string)Session["LocationText"];
            //btnGoAll_OnClick(null, null);
        }
    }
}

我也有一个按钮在physician.aspx页面，我想自动点击，所以它就像如果用户点击医师页面。

我只是需要一些帮助来弄清楚如何实现会话传输和自动填充。我应该在会话中获取文本或值，以及如何将其应用于physician.aspx页面?

我想我需要一个函数，在页面加载后执行，因为控件尚未初始化?

可以用Javascript实现这个功能吗?我如何使它与我通过c#接收的会话一起工作?

如何选择在另一个页面中选择的相同选项

你可以有一个像

public void OnBtnClick()
{
 // add the code with the query to database
}

在页面加载时你可以像这样调用这个函数

 protected void Page_Load(object sender, EventArgs e) {
        if (!Page.IsPostBack) {
            PopulatePhysician();
            ASPopulateLocation();
            ASPopulateSpecialty();
        }
        if (Session["LocationText"] != null && Session["SpecialtyText"] != null && Session["GenderText"] != null) {
            this.OnBtnClick();
        }
    }

和按钮点击事件处理程序只是再次调用公共函数

protected void btnGoAll_Click(object sender, EventArgs e) {
this.OnBtnClick();
}
