A better way to control the toolbar of the XlstListViewWebPart

Sometimes you may want to programmatically control how the toolbar of an XlstListViewWebPart is shown on the page. If you search it on the web, you may find that a lot people tried to accomplish it with .NET Reflection, like what was shown in this post. It reflected into SharePoint assembly and called an internal method. Using this way may be able to achieve the goal, but it is a totally bad idea because it broke the basic .NET programing rules. When an method was declared as internal, it meant not to be called publicly. Calling it with Reflection, typically to SharePoint, may raise the supportability concerns.

So are there a better way to achieve the goal? The answer is yes. For example, to hide the toolbar of an XlstListViewWebPart, you can simply use the following 3 lines of code.

[code language=”csharp”]
view.Toolbar = null;
view.Toolbar = @”<Toolbar Type=’None’ />”;

If you want to do other things with the toolbar, just replace the value of the 2nd line with the CAML of your toolbar. The view object in the above code is an SPView object. This way is simple, and more importantly we don’t use any internal method here.

Here we reach the end of this post. But if some of you may want to know how this way works, you can find it out by yourself with a reflector tool and checking how SPView.Toolbar property was implemented.
