    Default Highlight multiple rows in GridPanel

    Hello,

    I have a GridPanel that is listing up to 100 records and I have a separate panel that has a graphical representation of those records. When a user clicks on a node in the graphical panel, I want it to highlight the associated rows in the GridPanel. Is there a way to do this easily? If not, can someone point me in the right direction to a more complex solution?

    Thanks!

    Hi, you should change the style of rows you need like this:
    Code:
    Ext.fly(your_grid.getView().getRow(i)).addClass('x-grid3-summary-row td');
    Or you can set the rows you want selected.

    First, be sure that your Grid's RowSelectionModel allows for multi-row selection:

    Code:
    var g = new Ext.grid.GridPanel({
      sm: new Ext.grid.RowSelectionModel({singleSelect: false}),
      <...snip...>
    })
    Then you can use the RowSelectionModel to select/deselect any rows you want:

    Code:
    g.selModel.select(4, true);   // selects row 4 and keeps any existing selections.
    See the Ext.grid.RowSelectionModel docs for more info.
