Namespace: DevExpress.Export.Xl

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

Declaration

public class XlValuesFilter :
    IXlFilter,
    IXlFilterCriteria

Remarks

Create an instance of the XlValuesFilter class and assign it to the XlFilterColumn.FilterCriteria or IXlTableColumn.FilterCriteria property to define the filter criteria for a worksheet or table column, respectively. The XlValuesFilter.Values property allows you to specify cell values that should be included in the filtering results.

Use the XlValuesFilter.DateGroups property to filter a column by date and time values.

You can include blank cells in a filter by setting the XlValuesFilter.FilterByBlank property to true.

Example

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

// Start filtering data in the "Product" column by a list of values.
XlValuesFilter filter = new XlValuesFilter();
filter.Values.Add("Mascarpone Fabioli");
filter.Values.Add("Mozzarella di Giovanni");
sheet.AutoFilterColumns.Add(new XlFilterColumn(1, filter));
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();
