ExtJS: Limiting the number of rows on a GridPanel

I have a grid panel that loads data through a XML store. I cannot control how many i开发者_运维知识库tems the XML will return, but I want to limit the grid to showing x number of rows.

Sorry if this is basic, I couldnt find it via google

Cheers

Do you not want to show the rows beyond x for performance / too much data to visualize reason or do you want to really hide the records beyond x from the users?

If former, you can just setup pagination (it's pretty straight forward)

If later, you can use bensiu's suggestion. (using getRange())

Just use getRange () method in Store (XmlStore) when load data to GridPanel
