Event Data

The CustomDisplayText event's data class is DevExpress.XtraEditors.HtmlContentCustomDisplayTextEventArgs.

Remarks

The ${FieldName} syntax in HTML markup inserts values of fields/properties from the control’s data context (HtmlContentControl.DataContext). See Data Binding.

The CustomDisplayText event allows you to specify custom display text for bound field values. The event contains the following arguments:

• PropertyName — The name of the bound field for which you need to return custom text.
• Value — Specifies the bound field’s value.
• DisplayText — Gets or sets custom display text of the Value. The parameter initially contains the default text presentation of the Value object.

The following example handles the CustomDisplayText event to wrap e-mail addresses in apostrophes:

C#

private void htmlContentControl1_CustomDisplayText(object sender, HtmlContentCustomDisplayTextEventArgs e) {
    if(e.PropertyName == "Email")
        e.DisplayText = "'" + e.DisplayText + "'";
}

VB.NET

Private Sub HtmlContentControl1_CustomDisplayText(sender As Object, e As DevExpress.XtraEditors.HtmlContentCustomDisplayTextEventArgs) Handles HtmlContentControl1.CustomDisplayText
    If e.PropertyName = "Email" Then
        e.DisplayText = "'" & e.DisplayText & "'"
    End If

HTML

<div class='content'>${Email}</div>
