Have you ever noticed while coding when you have changed
the name of the list and then we you refer the list.title property, all you get
is the new name.
Yes, that is how it should be. You must be wondering what
the big deal in this is. Well, here is a catch in that.
When you write or call any method or property that
returns the list items path URL or document URL, you still will get the old
name of the library.
Here I have one library called Orders.
In a button click, I have written a code to change the
name of a list. you can do this even from UI by going to list settings and changing
the name.
protected void
btnNameChange_Click(Object sender, EventArgs e)
{
SPWeb currentsite = SPContext.Current.Web;
lblTitle.Text = string.Empty;
SPList
listOrders = currentsite.Lists.TryGetList("Orders");
if (listOrders != null)
{
lblTitle.Text = listOrders.Title;
listOrders.Title = "Orders New
Title";
listOrders.Update();
}
else
{
lblTitle.Text = "Orders list does not
exist";
}
}
Now we have a new title of the list.
Let’s click the button again.
See now we have got a message that list does not exist
because we have changed the name of the list. So in this situation, what one
should do if you already have code written which fetches a name of the list and
perform an action on it at many places?
Are you going to rewrite your code at all the places? Think
on this and you’ll get an idea how difficult this can be.
So here is a solution to this. Answer is very simple use
rootfolder property of a list that always gives you original name of the list.
Let’s change a code a little.
protected void
btnNameChange_Click(Object sender, EventArgs e)
{
SPWeb currentsite = SPContext.Current.Web;
lblTitle.Text = string.Empty;
SPListCollection lists = currentsite.Lists;
Boolean IsNotFound = true;
foreach (SPList
list in lists)
{
if
(list.RootFolder.Name.ToUpper() == "ORDERS")
{
IsNotFound = false;
lblTitle.Text = "Original Title:"
+ list.RootFolder.Name.ToString() + " and
Current Title " + list.Title;
list.Title = "Orders New Title";
list.Update();
break;
}
}
if (IsNotFound)
{
lblTitle.Text = "Orders list does not
exist";
}
}
And here is what you get
Hope you must have found this useful.
