Exporting Filtered Data Only
17 Feb 20223 minutes to read
You can export the filtered data by defining the resulted data in dataSource
property of PdfExportProperties
before export.
In the below Pdf exporting demo, We have gotten the filtered data by applying filter query to the grid data and then defines the resulted data in dataSource
property and pass it to PdfExport
method.
@Html.EJS().Grid("Grid").DataSource((IEnumerable<object>)ViewBag.DataSource).AllowPdfExport().ToolbarClick("toolbarClick").Columns(col =>
{
col.Field("OrderID").HeaderText("Order ID").Width("120").TextAlign(Syncfusion.EJ2.Grids.TextAlign.Right).Add();
col.Field("CustomerID").HeaderText("Customer Name").Width("150").Add();
col.Field("Freight").HeaderText("Freight").Width("120").Format("C2").TextAlign(Syncfusion.EJ2.Grids.TextAlign.Right).Add();
col.Field("ShipCountry").HeaderText("Ship Country").Width("120").Add();
}).AllowPaging().PageSettings(page => page.PageSize(5).PageCount(5)).AllowFiltering().Toolbar(new List<string>() { "PdfExport" }).Render()
<script>
function toolbarClick(args) {
var gridObj = document.getElementById("Grid").ej2_instances[0];
if (args.item.id === 'Grid_pdfexport') {
var pdfdata;
var query = gridObj.renderModule.data.generateQuery(); // get grid corresponding query
for (var i = 0; i < query.queries.length; i++) {
if (query.queries[i].fn == 'onPage') {
query.queries.splice(i, 1); // remove page query to get all records
break;
}
}
var data = @Html.Raw(Json.Encode(ViewBag.DataSource));
var fdata = new ej.data.DataManager({ json: data }).executeQuery(query).then((e) => {
pdfdata = e.result; // get all filtered records
var exportProperties = {
dataSource: pdfdata,
};
gridObj.pdfExport(exportProperties);
}).catch((e) => true);
}
}
</script>
public IActionResult Index()
{
ViewBag.DataSource = OrderDetails.GetAllRecords();
return View();
}
