Remarks

Find control-specific information (for ASPxGridView, ASPxCardView or ASPxVerticalGrid) in the sections below.

ASPxGridView

When a grid is filtered or sorted by display text (the GridDataColumnSettings.FilterMode or the ASPxGridBehaviorSettings.SortMode property is set to DisplayText), it forces the ASPxGridView.CustomColumnDisplayText event to fire. Since visible row indexes are not defined while filtering or sorting, you cannot use the current overload of the ASPxGridColumnDisplayTextEventArgs.GetFieldValue method to get a value of the non-processed row.

To determine that the event was initiated by filtering or sorting, use the ASPxGridColumnDisplayTextEventArgs.VisibleIndex property, which in this case, returns negative one (-1).

Grid View - Get Started

ASPxCardView

When a grid is filtered or sorted by display text (the GridDataColumnSettings.FilterMode or the ASPxGridBehaviorSettings.SortMode property is set to DisplayText), it forces the ASPxCardView.CustomColumnDisplayText event to fire. Since visible card indexes are not defined while filtering or sorting, you cannot use the current overload of the ASPxGridColumnDisplayTextEventArgs.GetFieldValue method to get a value of the non-processed card.

To determine that the event was initiated by filtering or sorting, use the ASPxGridColumnDisplayTextEventArgs.VisibleIndex property, which in this case, returns negative one (-1).

Card View - Get Started

ASPxVerticalGrid

When a grid is filtered or sorted by display text (the GridDataColumnSettings.FilterMode or the ASPxGridBehaviorSettings.SortMode property is set to DisplayText), it forces the ASPxVerticalGrid.CustomRowDisplayText event to fire. Since visible records are not defined while filtering or sorting, you cannot use the current overload of the ASPxGridColumnDisplayTextEventArgs.GetFieldValue method to get a value of the non-processed record.

To determine that the event was initiated by filtering or sorting, use the ASPxGridColumnDisplayTextEventArgs.VisibleIndex property, which in this case, returns negative one (-1).
