在ASP.NET中,要实现报表控件的自定义功能,你可以遵循以下步骤:
public class CustomReportViewer : ReportViewer
{
// 在这里添加自定义属性和方法
}
public class CustomReportViewer : ReportViewer
{
public string ReportDataSource { get; set; }
}
public class CustomReportViewer : ReportViewer
{
public string ReportDataSource { get; set; }
public void ExportToPdf()
{
// 实现将报表导出为PDF的逻辑
}
}
<customReportViewer ID="CustomReportViewer1" runat="server"></customReportViewer>
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
CustomReportViewer1.ReportDataSource = "YourDataSourceName";
}
}
public class CustomReportViewer : ReportViewer
{
// ...其他代码...
public event EventHandler ReportGenerated;
protected virtual void OnReportGenerated(EventArgs e)
{
ReportGenerated?.Invoke(this, e);
}
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
CustomReportViewer1.ReportDataSource = "YourDataSourceName";
CustomReportViewer1.ReportGenerated += CustomReportViewer1_ReportGenerated;
}
}
private void CustomReportViewer1_ReportGenerated(object sender, EventArgs e)
{
// 在这里处理报表生成完成后的操作
}
通过遵循这些步骤,你可以根据需要实现ASP.NET报表控件的自定义功能。
