    Working With Grouping view


    Hi
    I have a Grouping view which shows data in Gui like this

    -Group1 3 Items
    Item1 Count 3
    Item2 Count 4
    Item3 Count 2

    -Group2 2 Items
    Item1 Count 2
    Item2 Count 5

    Now i want to modify this text "3 Items" and "2 Items" after Group name and make it Total count of all the items.
    like

    -Group1 9 (3+4+2)
    Item1 Count 3
    Item2 Count 4
    Item3 Count 2

    -Group2 7 (2+5)
    Item1 Count 2
    Item2 Count 5


    can you pls provide some sample code or link whr i can find some help

    You could try:
    Code:
    groupTextTpl: '{text} ' +
      '<tpl exec="this.sum = 0"></tpl>' +
      '<tpl for="values.rs"><tpl exec="this.sum += values.data.count"></tpl></tpl>',
      '{[this.sum]} ' +
      '(<tpl for="values.rs"><tpl if="xindex &gt; 1">+</tpl>{values.data.count}></tpl>)'
    (have a look at the XTemplate API docs for details)

    Disclaimer: Completely untested code!

    I was having some similar issues.
    In 3.3, I got was able to get to the grouped records this way:

    Code:
    groupTextTpl: '<tpl for="values.rs">{values.data.start_date}</tpl>'                                      '
    Where start_date is a item in my records.
    In addition I added
    Code:
    <tpl if="xindex &lt; 2">
    so that I only get the start date for the first record, as I didn't need them all.
    The API incorrectly states that "rs" contains only one row's worth of data, when in fact it contains all rows that are in the group.

    For what its worth, the documentation for groupTextTpl could use some updated information about what values are available, and how to get to them. I like XTemplates, but they are tough to debug (unlike most other things in Ext), and each use of XTemplate is different... Extensive, accurate info is essential.
