Hide toolbar from List Form Web Part

If you have added list from web part in display mode and you want to protect that item from edit,delete and so on..You have to remove the toolbar then. There are two options to do this,
1. Open your custom page containing Web Part in SharePoint designer and convert the code in to XSLT format. Then select the toolbar from design mode and remove it.
2. If you can not convert it to the XSLT format, use the following javascript. Write it inside the ContentPlceHolder tag.


var newitm = GetElementByText("a", "New Item") // find out "New Item" link first i.e 'a' tag.

var toolbar = newitm.parentNode.parentNode.parentNode.parentNode.parentNode.parentNode.parentNode.parentNode.outerHTML; // find out the "table" tag as its parent node and its outerHTML.
if(toolbar != null)
{
newitm.parentNode.parentNode.parentNode.parentNode.parentNode.parentNode.parentNode.parentNode.outerHTML = ""; //Assign that table to NULL so that it will be invisible to the user.
}

function GetElementByText(tagName, title)
{
var a = document.getElementsByTagName(tagName);

for (var i=0; i < a.length; i++)
{
if (a[i].title)
{
if (a[i].title == title )
{
return a[i];
}
}
}
return null;
}


Remember this is just a work around. Not a secured and perfect solution to use.
