    [CLOSED] renderer column index is wrong after column lock & unlock

    The column index passed into renderer() function does not match the column list when column lock status changed.

    I can reproduce it with your locking grid column example.( Ext.Net 3.1)

    Hi @susanz,

    Technically, a GridPanel with locking enabled consists of two GridPanels - one from the locked part and one for the non-locked part. They are independent GridPanels. With own sets of columns as well and, therefore, with own indexing. Hope this information helps.

    Thanks.
