    [CLOSED] [1.0] GridPanel RowExpander Template

    Have a couple questions about the RowExpander plugin for the GridPanel.

    1. Is it possible to put conditional text inside the Template? I want to be able to show different text if a condition is met within the record.


    2. Is it possible to remove the Template altogether, if the the data that is within the Template doesn't exist?


    Thanks.

    Hi,

    You can paste any javascript expression to customize template.
    To hide template content you can set css class with 'display:none'

    Please see the following example. It hides template for records with price=50, also it has javascript expression
