I dont think this can be achieve OOTB features of sharepoint .
But i may be possible with the use of some programming
You can use event receiver to achieve this.
- When an Item is adding in the list check foe the count of a list
- if count is 10 then cancel the event.
public override void ItemAdding(SPItemEventProperties properties)
{
SPWeb web = properties.OpenWeb();
SPList list = web.Lists[properties.ListId];
if (list.ItemCount == 10)
{
properties.Cancel = true;
}
else
{
base.ItemAdding(properties);
}
}
Hope this helps
