XlCustomFilterCriteria Class

Specifies a criterion value and comparison operator for a custom filter.

Namespace: DevExpress.Export.Xl

Assembly: DevExpress.Printing.v21.2.Core.dll

Declaration

public class XlCustomFilterCriteria

The following members accept/return XlCustomFilterCriteria objects:

Remarks

Create an instance of the XlCustomFilterCriteria class to define a filter criterion for a custom filter (XlCustomFilters). Specify a filter value (XlCustomFilterCriteria.Value) and a comparison operator (XlCustomFilterCriteria.FilterOperator).

Pass the created XlCustomFilterCriteria object to the XlCustomFilters constructor as a parameter to create the filter expression. If you create a complex filter expression containing two filter criteria, specify what logical operator (“AND” or “OR”) should be used to combine these criteria (XlCustomFilters.And).

Refer to the Filtering article to learn more about filtering in the Excel Export Library.

Example

// Generate the header row.
using (IXlRow row = sheet.CreateRow())
    row.BulkCells(new string[] { "Region", "Product", "Sales" }, headerRowFormatting);

// Create a custom filter to display values in the "Sales" column that are greater than $4500.
XlCustomFilters filter = new XlCustomFilters(new XlCustomFilterCriteria(XlFilterOperator.GreaterThanOrEqual, 4500));
sheet.AutoFilterColumns.Add(new XlFilterColumn(2, filter));
// Start filtering data.
sheet.BeginFiltering(sheet.DataRange);

// Generate data for the document.
string[] products = new string[] { "Camembert Pierrot", "Gorgonzola Telino", "Mascarpone Fabioli", "Mozzarella di Giovanni" };
int[] amount = new int[] { 6750, 4500, 3550, 4250, 5500, 6250, 5325, 4235 };
for (int i = 0; i < 8; i++)
{
    using (IXlRow row = sheet.CreateRow())
    {
        using (IXlCell cell = row.CreateCell())
        {
            cell.Value = (i < 4) ? "East" : "West";
            cell.ApplyFormatting(rowFormatting);
        }
        using (IXlCell cell = row.CreateCell())
        {
            cell.Value = products[i % 4];
            cell.ApplyFormatting(rowFormatting);
        }
        using (IXlCell cell = row.CreateCell())
        {
            cell.Value = amount[i];
            cell.ApplyFormatting(rowFormatting);
        }
    }
}

// Finish filtering.
sheet.EndFiltering();
