ListViewWebPart: Programmatically setting the ToolbarType property


While working on a migration project we came across a requirement whereby ListViewWebPart’s had to be added to a page programmatically. The ListViewWebPart class has a property called toolbartype. Setting the toolbartype property sounds simple enough. I mean how difficult can it be to set a property?

The problem is that it is a read only property. We thought maybe we can set it via reflection. After searching a bit on google we found a couple of suggestions on how it could be done (most of them were solutions on how to set it to none). One method seemed to have solved our problem until we installed the latest infrastructure updates. Then it completely stopped working. However luckily for us Tony Stegeman and Brian Farhill came up with a solution.

Below you can see the complete solution that worked for us:


private static void SetToolbarType(SPView spView, string toolBarType)
{
    spView.GetType().InvokeMember(
"EnsureFullBlownXmlDocument",
    BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.InvokeMethod,
    null, spView, null, System.Globalization.CultureInfo.CurrentCulture);
    PropertyInfo nodeProp = spView.GetType().GetProperty("Node",
    BindingFlags.NonPublic | BindingFlags.Instance);
    XmlNode node = nodeProp.GetValue(spView, null) as XmlNode;
    XmlNode toolbarNode = node.SelectSingleNode("Toolbar");
    if (toolbarNode != null)
    {
        toolbarNode.Attributes[
"Type"].Value = toolBarType;
        // If the toolbartype is Freeform (i.e. Summary Toolbar) then we need to manually 
        // add some CAML to get it to work.
        if (String.Compare(toolBarType, "Freeform", true, System.Globalization.CultureInfo.InvariantCulture) == 0)
        {
            string newItemString = "";
            XmlAttribute positionNode = toolbarNode.OwnerDocument.CreateAttribute("Position");
            positionNode.Value =
"After";
            toolbarNode.Attributes.Append(positionNode);
            switch (spView.ParentList.BaseTemplate)
            {
                case SPListTemplateType.Announcements:
                    newItemString =
"announcement";
                    break;
                case SPListTemplateType.Events:
                    newItemString =
"event";
                    break;
                case SPListTemplateType.Tasks:
                    newItemString =
"task";
                    break;
                case SPListTemplateType.DiscussionBoard:
                    newItemString =
"discussion";
                    break;
                case SPListTemplateType.Links:
                    newItemString =
"link";
                    break;
                case SPListTemplateType.GenericList:
                    newItemString =
"item";
                    break;
                case SPListTemplateType.DocumentLibrary:
                    newItemString =
"document";
                    break;
                default:
                    newItemString =
"item";
                    break;
            }
            if (spView.ParentList.BaseType == SPBaseType.DocumentLibrary)
            {
                newItemString =
"document";
            }
            // Add the CAML
            toolbarNode.InnerXml = @"<IfHasRights><RightsChoices><RightsGroup PermAddListItems=""required"" /></RightsChoices><Then><HTML><![CDATA[ <table width=100% cellpadding=0 cellspacing=0 border=0 > <tr> <td colspan=""2"" class=""ms-partline""><IMG src=""/_layouts/images/blank.gif"" width=1 height=1 alt=""""></td> </tr> <tr> <td class=""ms-addnew"" style=""padding-bottom: 3px""> <img src=""/_layouts/images/rect.gif"" alt="""">&nbsp;<a class=""ms-addnew"" ID=""idAddNewItem"" href=""]]></HTML><URL Cmd=""New"" /><HTML><![CDATA["" ONCLICK=""javascript:NewItem(']]></HTML><URL Cmd=""New"" /><HTML><![CDATA[', true);javascript:return false;"" target=""_self"">]]></HTML><HTML>Add new " + newItemString + @"</HTML><HTML><![CDATA[</a> </td> </tr> <tr><td><IMG src=""/_layouts/images/blank.gif"" width=1 height=5 alt=""""></td></tr> </table>]]></HTML></Then></IfHasRights>";
        }
        spView.Update();
}

    Sharepoint customisation is a right pain, is there anyway to avoid using CAML for things like list view rendering?

    An impressive share! I’ve just forwarded this onto a co-worker who has been conducting a little homework on this. And he actually ordered me lunch due to the fact that I discovered it for him… lol. So allow me to reword this…. Thanks for the meal!! But yeah, thanks for spending time to discuss this topic here on your site.
