Assembly: DevExpress.Web.ASPxHtmlEditor.v19.2.dll

Declaration

public class ToolbarUndoButton :

Remarks

The ASPxHtmlEditor keeps track of all user actions, and allows you to undo or repeat them by using the Undo and Redo buttons (ToolbarUndoButton and ToolbarRedoButton).

You can add the Undo button to toolbars by using either the ASPxHtmlEditor designer at design time, or programmatically.

protected void Page_Load(object sender, EventArgs e) {
    HtmlEditorToolbar stToolbar1 = HtmlEditorToolbar.CreateStandardToolbar1();
    ToolbarUndoButton undo = new ToolbarUndoButton();
    stToolbar1.Items.Add(undo);
    ASPxHtmlEditor1.Toolbars.Add(stToolbar1);
}
