Event Data

The SearchFormShowing event's data class is SearchFormShowingEventArgs. The following properties provide information specific to this event:

Property Description
ActivePage Obtains what tab of the Find and Replace dialog (Find or Replace) is active.
ControllerParameters Gets the information for initializing the Find and Replace dialog controls.
DialogResult Gets or sets the return value of a dialog box. Inherited from ShowFormEventArgs.
Handled Gets or sets whether an event was handled. If it was handled, the default actions are not required. Inherited from ShowFormEventArgs.
Parent Gets or sets a parent of the form being shown. Inherited from ShowFormEventArgs.


Handle the SearchFormShowing event to perform the required actions before a search form is displayed. Use the SearchFormShowingEventArgs.ActivePage property of the event’s argument to determine what tab is active on the search form - Find or Replace.


The RichEditControl.ShowSearchForm and RichEditControl.ShowReplaceForm methods trigger the SearchFormShowing event.


This example demonstrates how handle the RichEditControl.SearchFormShowing event to replace the standard Find and Replace dialog with a custom dialog.

private void richEditControl1_SearchFormShowing(object sender, SearchFormShowingEventArgs e)
    string curWord = richEditControl.Document.GetText(richEditControl.Document.Selection);
    using (MySearchTextForm form = new MySearchTextForm(e.ControllerParameters, curWord))
        e.DialogResult = form.ShowDialog();
        e.Handled = true;
using System.Drawing;
using DevExpress.XtraRichEdit.Forms;

namespace CustomDialogs
    public partial class MySearchTextForm : SearchTextForm
        public MySearchTextForm(SearchFormControllerParameters controllerParameters, string searchWord)
            : base(controllerParameters)
            lblFndDirection.Location = new Point (lblFndDirection.Location.X - 10, lblFndDirection.Location.Y);
            lblFndDirection.Text = "Direction:";
            cbFndSearchString.Text = searchWord;
            chbFndRegex.Enabled = false;
