    [CLOSED] Command Button not rendering in Collapsed Group in Grid

    In the following example, I have group set to startCollapsed=true and have 2 command buttons. They do not render. I have to use grid.view.refreshNode(index) to render the whole row again and then they appear. What should I do to make them render by default.

    Hi @amitpareek,

    First of all, please clarify what Ext.NET version are you using?
  3. #3
    I am using v2.1
  4. #4
    The official release?
  5. #5
    Downloaded last week from SVN.

    However, it was the same in release version too.
  6. #6
    Probably, you have updated from the branches/2.

    The latest Ext.NET is here:

    Running your sample with the latest Ext.NET there are the problems, but they differs from the one which you described.

    They are:

    1. StartCollapsed="true" doesn't work (if I am not wrong it doesn't work with v2.1 as well...). Here is a but report to Sencha.

    There is a workaround (I have not tested yet).

    2. The updateTotal function causes a JavaScript error. We will investigate.
  7. #7
    I cannot use trunk as it uses ExtJS 4.2

    Can u just test ur case in v2.1 from branches/2.1? startCollapsed works but buttons dont appear after expand.
  8. #8
    Also just before I load data, I set it to startCollapsed=true because after loading data, for some reason, it is again reset to false. So I have to set it to true everytime I load data. But this issue is altogether a different issue than I am mentioning.

    The buttons do not render when group is collapsed by default.

    I cannot use trunk as it uses ExtJS 4.2
    What is reason for not using Ext JS 4.2?

    Hi Geoff,
    Our app is live and hence we cannot push 4.2 until we have thoroughly tested it. We may start looking at it probably in next 10-15 days. How stable it is now? We cannot take risks of unknown bugs coming up randomly.

    This issue is critical, as we have to render each row on groupClick event which slows down the UI when there are more than 200-300 items in a group and hence I am looking for an immediate fix, somekind of override which I can implement now.
