The FilterControlCustomValueDisplayText event's data class is FilterControlCustomValueDisplayTextEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| DisplayText | Gets or sets the display text of the entered filter value. |
| EncodeHtml | Gets or sets a value that specifies whether the filter value display text keeps any of its values that are HTML as HTML, or instead, strips out the HTML markers. |
| PropertyInfo | Gets the filterable property of the filter expression. |
| Value | Gets the custom value entered into the filter bar by an end user. |
The FilterControlCustomValueDisplayText event enables you to provide a custom display text for the filter value entered into the built-in filter control’s filter condition. This custom text is displayed within a condition value editor when it’s inactive.
The event’s Value property allows the currently entered value to be obtained. Set the DisplayText property to specify the value’s custom display text, if required.
