Hiding ECB menus selectively based on an item property
I needed to hide context menu item “Edit Document”, for files of a particular type (which SharePoint determines from the file extension). Here's is how I achieved it :
The menu Item “Edit Document” is rendered via AddDocLibMenuItems function in CORE.JS. Possible approaches to achieve this override in a supported way :
Option1 :
a)Create a customCORE.JS
b)Add extra code, explained in next few lines below in AddDocLibMenuItems function
c)Create a custom masterpage and add a scriptlink for customCORE.js
Option2:
Similar to above option, but instead of creating customCORE.js, we can override either the AddDocLibMenuItems or add an implementation of Custom_AddDocLibMenuItems on the masterpage itself in a script tag, after the scriptlink for CORE.js <SharePoint:ScriptLink language="javascript" name="core.js" Defer="true" runat="server" />)
Option3:
If the change is needed only on one page(View Page of one Library), add a CEWP with an implementation of Custom_AddDocLibMenuItems, which is identical to AddDocLibMenuItems from CORE.js + additional check for the file extension talked about below.
We can override the AddDocLibMenuItems function to not to render the “Edit Document” menu, when the file is of a particular file extension.(In below example, I am checking if it’s a .txt file, then skip the part that renders the “Edit Document” menu.)Below highlighted, is the code that I put in the AddDocLibMenuItems in CORE.js
function AddDocLibMenuItems(m, ctx)
{
...
else
{
var strExt = GetAttributeFromItemTable(itemTable, "Ext", "FileType");
if(strExt != "txt")
{
var objEditor=StsOpenEnsureEx(currentItemOpenControl+".3");
if (objEditor !=null )
strDisplayText=L_EditInApplication_Text;
}
}
if (strDisplayText !="")
{
strAction="editDocumentWithProgID2('"+currentItemFileUrl+"', '"+currentItemProgId+"', '"
+currentItemOpenControl+"', '"+bIsCheckout+"', '"+ctx.HttpRoot+"', '"+currentItemCheckedoutToLocal+"')";
strImagePath=ctx.imagesPath+currentItemIcon;
menuOption=CAMOpt(m, strDisplayText, strAction, strImagePath, null, 240);
menuOption.id="ID_EditIn_"+currentItemAppName;
}
}
}
}
}
...
}
HTH & Happy Customizing SharePoint !!
