Example
The following code example shows how to use this drop-down item to sort or filter. This code example is part of a larger example provided for the ColumnHeaderCell.DropDownList property.
void setSecondColumnDropDownListButton_Click(object sender, EventArgs e)
        {
            // Create a header drop down list without default down down items.
            HeaderDropDownList headerDropDownList = new HeaderDropDownList();

            // If you do not indicate which cell to filter, the cell with the same index as the column header cell in the row       
      // section is filtered.
            headerDropDownList.CellName = "textBoxCell2";

            DropDownItemCollection dropDownItemCollection = headerDropDownList.Items;
            // Initialize drop down items manually.
            // Add sort item.
            dropDownItemCollection.Add(new DropDownSortItem(SortOrder.Ascending));
            dropDownItemCollection.Add(new DropDownSortItem(SortOrder.Descending));
            
            // Add a separator line.
            dropDownItemCollection.Add(new DropDownSeparatorItem());

            // Add show all, black and none black items.
            dropDownItemCollection.Add(new DropDownShowAllFilterItem());
            dropDownItemCollection.Add(new DropDownBlanksFilterItem());
            dropDownItemCollection.Add(new DropDownNonBlanksFilterItem());

            // Add auto filter items.
            dropDownItemCollection.Add(new DropDownAutoFilterItem());

            // Get second column header cell.
            ColumnHeaderCell columnHeaderCell = this.gcMultiRow1.ColumnHeaders[0][1] as ColumnHeaderCell;
            columnHeaderCell.DropDownList = headerDropDownList;
        }
Private Sub setSecondColumnDropDownListButton_Click(ByVal sender As Object, ByVal e As EventArgs) Handles 
setSecondColumnDropDownListButton.Click
        ' Create a header drop down list without default down down items.
        Dim headerDropDownList As New HeaderDropDownList()

        ' is filtered.
        headerDropDownList.CellName = "textBoxCell2"

        Dim dropDownItemCollection As DropDownItemCollection = headerDropDownList.Items
        ' Initialize drop down items manually.
        ' Add sort item.
        dropDownItemCollection.Add(New DropDownSortItem(SortOrder.Ascending))
        dropDownItemCollection.Add(New DropDownSortItem(SortOrder.Descending))

        ' Add a separator line.
        dropDownItemCollection.Add(New DropDownSeparatorItem())

        ' Add show all, black and none black items.
        dropDownItemCollection.Add(New DropDownShowAllFilterItem())
        dropDownItemCollection.Add(New DropDownBlanksFilterItem())
        dropDownItemCollection.Add(New DropDownNonBlanksFilterItem())

        ' Add auto filter items.
        dropDownItemCollection.Add(New DropDownAutoFilterItem())

        ' Get second column header cell.
