DevExpress.XtraReports根据窗体控件值来显示打印数据

例举如下：



1、在上面窗口中，打印预览时，打印格式中显示的数据只是包含uName字段的值，则在Preview的单击事件中写

            XtraReport1 report = new XtraReport1();          

           (report.DataSource as CCDBDataSet).Tables[0].DefaultView.RowFilter = "uName like'"+"%"+textEdit1.Text +"%"+"'";  

            report.ShowPreview();

2、在上面窗口中，打印预览时，打印格式中显示的数据只是等于uName字段的值，则在Preview的单击事件中写

           XtraReport1 report = new XtraReport1();

           string uName= textEdit1.Text.Trim();

          //(report.DataSource as CCDBDataSet).Tables[0].DefaultView.RowFilter = "uName ='"+textEdit1.Text.Trim();

            (report.DataSource as CCDBDataSet).Tables[0].DefaultView.RowFilter = "uName =" + uName;

            //Show the report's preview.

            report.ShowPreview();
