DevExpress 获取gridview输入的查询筛选值

Posted 2022-08-01 小飞鱼通达二开

在需要导出表格数据时需要，先获取输入的过滤值，可以通过以下代码获取：

            string shortNameSearchStr = "";
            //获取输入的过滤值
            if (gridView1.FocusedColumn.FieldName == "简称" )
               
                customerShortNameSearchStr = gridView1.Columns["简称"].FilterInfo.Value.ToString();
            

设置需要导出的内容

            string sql = "Select * from v2_order where 1=1";
            if (customerShortNameSearchStr!="")
            
                sql += " and 简称='"+shortNameSearchStr + "'";
            
            sql += " order by 业务日期, 提货Id";
            var dataTableCollection = new CommonData().GetDataSet( sql ).Tables;
            if (dataTableCollection != null)
            
                DataTable datasource = dataTableCollection[0];
                if (datasource == null)
                
                    XtraMessageBox.Show("无法导出数据,请检查");
                
                Export(datasource);
            

导出方法：

        public void Export(DataTable datasource)
        
            SaveFileDialog saveFileDialog = new SaveFileDialog();
            saveFileDialog.DefaultExt = "xls";
            saveFileDialog.Filter = "Excel文件|*.xls";

            string filename = "order_" + DateTime.Now.ToString("yyyyMMdd") + "_" + DateTime.Now.Hour.ToString() + "." +
                              DateTime.Now.Minute.ToString();
            saveFileDialog.FileName = filename;

            if (saveFileDialog.ShowDialog() == DialogResult.OK)
            
                GridControl grid = new GridControl();
                ;
                GridView view = new GridView();
                grid.ViewCollection.Add(view);
                grid.MainView = view;
                view.GridControl = grid;

                foreach (DataColumn dc in datasource.Columns)
                
                    GridColumn gridColumnNumber = view.Columns.AddVisible(dc.ColumnName);
                    gridColumnNumber.FieldName = dc.ColumnName;

                

                grid.DataSource = datasource;
                this.Controls.Add(grid);                            //重要  
                grid.ForceInitialize();                             //重要  


                view.BestFitColumns();
                
                view.HorzScrollVisibility = DevExpress.XtraGrid.Views.Base.ScrollVisibility.Always;
                view.OptionsPrint.AutoWidth = false;

                view.ExportToXls(saveFileDialog.FileName);
                XtraMessageBox.Show("导出成功");
