*Moved to: http://fluentbytes.com/how-to-remove-a-toolbar-header-from-a-sharepoint-web-part/
Yes you read it correct, I did some SharePoint development last week. And I must say It was quite a challenge. I was just helping out on a project where we created a feature that combines a custom list deployment with the deployment of a custom page. On this page we place web parts that provide a view to the custom list.
Now the challenge I faced was to get the deployment working in such a way that we add web parts to the page not showing the toolbar. At first I just laugh and said that I would fix that for them in a few minutes, assuming I could just use the object model, set a toolbar property to false and from that point on have a big hug from my colleague.
Well I was wrong. Removing a toolbar from a webpart using the object model is something that is just not supported. You can read more about this in e.g. this forum thread.
After some digging around I finally got the problem solved. I thought I would provide the code snippet here, so you can leverage it.
private static void DisableToolbar(ListViewWebPart lv)
{
// Extract view
System.Reflection.PropertyInfo ViewProp = lv.GetType().GetProperty(“View”,
System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
SPView spView = ViewProp.GetValue(lv, null) as SPView;
string txt = spView.SchemaXml;
System.Reflection.PropertyInfo NodeProp = spView.GetType().GetProperty(“Node”,
System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
XmlNode node = NodeProp.GetValue(spView, null) as XmlNode;
XmlNode tBarNode = node.SelectSingleNode(“Toolbar”);
if (tBarNode != null)
{
XmlAttribute typeNode = tBarNode.Attributes[“Type”];
// make the contents empty so we realy remove the toolbar …..
// otherwise you might get a different type of toolbar popup when we have a
// Migrated site from 2.0
tBarNode.RemoveAll();
// re-add the type attribute
tBarNode.Attributes.Append(typeNode);
// finally set the toolbar to not show….
typeNode.Value = “None”;
}
//This forces a refresh of the views internal xml or the node’s cild nodes are not populated
spView.Update();
}
