The event handler receives an argument of type SearchFormShowingEventArgs containing data related to this event.
Handle the SearchFormShowing event to perform the required actions before a search form is displayed. Use the DevExpress.XtraRichEdit.SearchFormShowingEventArgs.ActivePage property of the event's argument to determine what tab is active on the search form - Find or Replace.
Example
This example demonstrates how to replace the standard Find and Replace dialog with a custom one via the SearchFormShowing event.
| Form1.cs |
private void richEditControl1_SearchFormShowing(object sender, SearchFormShowingEventArgs e)
{
string curWord = richEditControl1.Document.GetText(richEditControl1.Document.Selection);
MySearchTextForm form = new MySearchTextForm(e.ControllerParameters, curWord);
e.DialogResult = form.ShowDialog();
e.Handled = true;
}
