TaskReportPage.aspx 页面中,我有 startdate,enddate,dropdown 和一个下载按钮。

代码如下所示:

 <fieldset>
    <legend>Enter The Details To Download Report</legend>
    <div class="label">
        Start Date :<asp:TextBox runat="server" ID="txtStartDate" />
    </div>
    <div class="label">
        End Date:
        <asp:TextBox runat="server" ID="txtEndDate"></asp:TextBox>
    </div>
    <div class="label">
        Employee Name:
        <asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="true" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
            <asp:ListItem Value="AllRecords">All Records</asp:ListItem>
        </asp:DropDownList>
    </div>
    <div>
        <asp:Button ID="btndisplay" runat="server" Text="View Report" OnClick="btndisplay_Click">
        </asp:Button>
        <asp:Button runat="server" ID="Download" align="center" Text="Download" OnClick="Download_Click">
        </asp:Button>
    </div>
    <div class="value">
        <asp:Label ID="lblMessage" runat="server" Visible="false" Style="color: Red"></asp:Label>
    </div>
</fieldset>

TaskReportPage.aspx.cs 文件中,我可以从 TaskReportPage.aspx 页面获取值。

在后端我有一个包含这些列的表:

Description varchar(500),
CreatedDate datetime,
StatusId int,
UserId int,
Hour int,
Day varchar(10)

我编写了一个用于从数据库中检索值的存储过程,如下所示:

ALTER PROCEDURE [dbo].[RetriveDatatable]  
(  
    @StartDate datetime,
    @EndDate datetime,
    @Dropdown varchar(50),
    @ID INT
)
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for procedure here

    SELECT Day, t.CreatedDate, Description, Hour, Firstname
    FROM tbl_TaskType t, tbl_UserDetails u
    WHERE t.CreatedDate BETWEEN '@StartDate' AND '@EndDate'
    AND u.ID=(SELECT ID FROM tbl_UserDetails WHERE FirstName=@Dropdown);
END

我在 Eye1.designer.cs 文件中导入此存储过程:

此文件遵循实体框架程序。

看起来像:

public int RetriveDatatable(Nullable<global::System.Int32> userID, Nullable<global::System.DateTime> startDate, Nullable<global::System.DateTime> endDate, global::System.String dropdown = dropdowntParameter1)
{
    ObjectParameter userIDParameter;
    if (userID.HasValue)
    {
        userIDParameter = new ObjectParameter("UserID", userID);
    }
    else
    {
        userIDParameter = new ObjectParameter("UserID", typeof(global::System.Int32));
    }

    ObjectParameter startDateParameter;
    if (startDate.HasValue)
    {
        startDateParameter = new ObjectParameter("StartDate", startDate);
    }
    else
    {
        startDateParameter = new ObjectParameter("StartDate", typeof(global::System.DateTime));
    }

    ObjectParameter endDateParameter;
    if (endDate.HasValue)
    {
        endDateParameter = new ObjectParameter("EndDate", endDate);
    }
    else
    {
        endDateParameter = new ObjectParameter("EndDate", typeof(global::System.DateTime));
    }

    ObjectParameter dropdowntParameter;
    if (dropdown != null)
    {
        dropdowntParameter = new ObjectParameter("Dropdown", dropdown);
    }
    else
    {
        dropdowntParameter = new ObjectParameter("Dropdown", typeof(global::System.String));
    }

    return base.ExecuteFunction("RetriveDatatable", userIDParameter,startDateParameter, endDateParameter, dropdowntParameter);
}

最后我的问题是我想将 startdate,enddate和dropdown 参数值从 TaskReportPage.aspx.cs 页面发送到 eye1.disigner.cs 文件页面。然后它将调用SP,我从数据库获取数据到 TaskReportPage.aspx.cs

请帮帮我.......

您不应该在设计器文件中编辑任何代码 - 它仅由visual studio生成和使用,最终会被覆盖,您将失去手动更改。请将您添加到设计器文件中的所有代码移动到aspx.cs文件中。
