Save and Restore Layout

• Aug 01, 2019

ASPxHtmlEditor allows you to save its layout to a database, and then restore it. This information includes all settings that control the visibility and size of visual elements, their appearance settings, etc.

The editor’s ASPxHtmlEditor.ClientLayout event enables you to save the editor’s layout each time it is changed and restore it on the first page load. This event provides the ASPxClientLayoutArgs.LayoutMode property, which indicates whether the editor’s layout should be saved or restored.

The following example demonstrates how to save/restore the ASPxHtmlEditor layout to/from a data store.

C#

protected void ASPxHtmlEditor1_ClientLayout(object sender, 
  DevExpress.Web.ASPxClientLayoutArgs e) {
    if (e.LayoutMode == DevExpress.Web.ClientLayoutMode.Saving) {
        SaveUserLayoutToDatabase(userID, "AccountTreeList", e.LayoutData);
    }
    else {
        if (System.IO.File.Exists(fileName))
            e.LayoutData = RestoreUserLayoutFromDatabase(userID, "AccountTreeList");
    }
}

VB.NET

Protected Sub ASPxHtmlEditor1_ClientLayout(sender As Object, _
  e As DevExpress.Web.ASPxClientLayoutArgs)
   If e.LayoutMode = DevExpress.Web.ClientLayoutMode.Saving Then
      SaveUserLayoutToDatabase(userID, "AccountTreeList", e.LayoutData)
   Else
      If File.Exists(fileName) Then
         e.LayoutData = RestoreUserLayoutFromDatabase(userID, "AccountTreeList")
      End If
   End If
End Sub
