Remove per page limit

Go into the View settings, there is an "Item Limit" towards the bottom of the page.  Bump it up.

You can see this limit by selecting the hyperlink button:

From the content edit toolbar:

Select Browse

and, assuming you have more than 30(depends on you) pages in the directory, you’ll see the 30((depends on you)) item limit

The default is set at 15 pages, but you can quickly and easily fix that.

Open: AssetPortalBrowser.aspx

Loaction: C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\LAYOUTS\AssetPortalBrowser.aspx
Go to: Line number: 96
Edit: PageSize=”15¿
Change the 15 to your desired value.type how much pages you want.

Two questions:
1. If you change the 15 to your desired value, it will change all lists in Sharepoint?
2. Suppose I have big line number of 10000, I have to calculate it. But I just want to display all in one page without math.

You might be able to set the Item Limit to "0", which would show all items on one page.  However, I have to say if you do this it could really affect performance if you are trying to view thousands of records on one page.

No, I tried "0" but failed. The number must be greater than 1.
