Remarks
The ShowFilterPopupExcel event allows you to customize the Excel-style filter popup. For instance, you can use the e.IsRadioMode event parameter to disable multiselection. Other event parameters (such as e.ShowNulls and e.ShowBlanks) allow you to hide specific filter conditions from the Filters tab.
The following code sample uses the e.HideFilter method to hide operators from the Filters tab:
void PivotGridControl_ShowFilterPopupExcel(object sender, FilterPopupExcelEventArgs e) {
if (e.Field == fieldModelPrice) {
e.HideFilter(DevExpress.Utils.Filtering.Internal.CustomUIFilterType.BelowAverage);
e.HideFilter(DevExpress.Utils.Filtering.Internal.CustomUIFilterType.Between);
e.HideFilter(DevExpress.Utils.Filtering.Internal.CustomUIFilterType.BottomN);
e.HideFilter(DevExpress.Utils.Filtering.Internal.CustomUIFilterType.Custom);
e.HideFilter(DevExpress.Utils.Filtering.Internal.CustomUIFilterType.DoesNotEqual);
e.HideFilter(DevExpress.Utils.Filtering.Internal.CustomUIFilterType.InRange);
e.HideFilter(DevExpress.Utils.Filtering.Internal.CustomUIFilterType.LessThan);
e.HideFilter(DevExpress.Utils.Filtering.Internal.CustomUIFilterType.LessThanOrEqualTo);
}
}
