Remarks

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.

C#

protected void grid_FilterControlCustomValueDisplayText(object sender, FilterControlCustomValueDisplayTextEventArgs e) {
    if (e.PropertyInfo.PropertyName == "NeedAlert") {
        if (e.Value == null)
            return;
        e.DisplayText = (bool)e.Value ? "Need alert" : "Is's ok";
    }
}
