Question

我希望我的报告显示库存少于搜索文本框中插入的值的所有产品。有错误。

这是存储过程：

CREATE PROCEDURE [dbo].[GetInventoryReport]
    @Stock int
AS
    SELECT * 
    FROM Product
    WHERE Stock < @Stock
    ORDER BY Stock ASC

这是用户在搜索文本框中输入值时的代码。

private void txtSearch_TextChanged(object sender, EventArgs e)
{
    DataTable dtbl = GetInventoryReport_Result();

    rptInventoryStock.Visible = true;
    rptInventoryStock.LocalReport.ReportPath = "InventoryReport.rdlc";
    rptInventoryStock.LocalReport.DataSources.Clear();

    rptInventoryStock.LocalReport.Add(new ReportDataSource("IOOP_DatabaseDataSet", dtbl));

    this.rptInventoryStock.RefreshReport();
}

这是GetInventoryReport_Result()：

的功能

private DataTable GetInventoryReport_Result()
{
    DataTable dtbl = new DataTable();

    try
    {
        SqlCommand sqlCmd = new SqlCommand("GetInventoryReport", sqlCon);
        sqlCmd.CommandType = CommandType.StoredProcedure;
        sqlCmd.Parameters.AddWithValue("@Stock", txtSearch.Text.Trim());

        SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd);
        sqlDa.Fill(dtbl);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message, "Error Message");
    }
    finally
    {
        if (sqlCon != null)
            sqlCon.Close();
    }

    return dtbl;
}

错误：

'Microsoft.Reporting.WinForms.LocalReport'不包含 “添加”的定义，没有扩展方法“添加”接受第一个 “Microsoft.Reporting.WinForms.LocalReport”类型的参数可以是发现（您是否缺少using指令或程序集引用？）

您错过了<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.min.js"></script> <div ng-app="app" ng-controller="ctrl"> <form name="form" ng-submit="submit()" novalidate> <div> <select name="select" ng-model="selectedOption" ng-options="option as option.text for option in options" required> <option value="">--Please select--</option> </select> </div> <div ng-if="form.select.$invalid && form.$submitted">Please make a selection</div> <div> Selected option is valid: {{form.select.$valid}} </div> </form> </div>

<强>替换

.DataSources

。通过

rptInventoryStock.LocalReport.Add(new ReportDataSource("IOOP_DatabaseDataSet", dtbl));

在报表查看器中设置参数
