    [CLOSED] Grid rowbody feature

    Hi.
    I am using grid with RowBody feature and GetAdditionalData function.

    function GetAdditionalDataFn(record, rowIndex, rowValues) {
        var headerCt = this.view.headerCt,
                colspan = headerCt.getColumnCount();    
        var body = "";
        if (rowIndex === index2)
            body = html2;
        return {
            rowBody: body,
            rowBodyCls: this.rowBodyCls,
            rowBodyColspan: colspan
        };
    }
    This code calls 4 times and insert the same data 2 times. Why the same data inserted 2 times?

    Hi @RRD,

    RowExpander uses RowBody internally. So, with your RowBody in the GridPanel's Features, there are two RowBodies in the GridPanel. I think it is not supposed to happen. I mean that there must be a single RowBody feature. You should refuse from either RowExpander or RowBody.
  5. #5
    I need RowExpander and I need to add data with colspan. How can I implement it?
  6. #6
    I think it's a bug with 2 data inserted because if I expand and collapse row then only one data left inserted.
  7. #7
    I am afraid it cannot be considered as a bug since these things - RowExpander and RowBody - cannot be used at the same time.
  8. #8
    How can I add data to grid with colspan without using RowBody and without removing RowExpander?

    I would try to override a RowExpander's getRowBodyFeatureData. The original code is:
    getRowBodyFeatureData: function(record, idx, rowValues) {
        var me = this;
        me.self.prototype.setupRowData.apply(me, arguments);
    
        rowValues.rowBody = me.getRowBodyContents(record);
        rowValues.rowBodyCls = me.recordsExpanded[record.internalId] ? '' : me.rowBodyHiddenCls;
    }
    For example, this override:
    Ext.ux.RowExpander.override({
        getRowBodyFeatureData: function(record, idx, rowValues) {
            var me = this;
                    
            me.self.prototype.setupRowData.apply(me, arguments);
            rowValues.rowBody = me.getRowBodyContents(record);
    
            if (idx === 0) {
                rowValues.rowBody = "<div>This is div</div>";
                 rowValues.rowBodyCls = '';
            } else {
                rowValues.rowBodyCls = me.recordsExpanded[record.internalId] ? '' : me.rowBodyHiddenCls;
            }
        }
    });
    Please note that with your scenario this
    <div>This is div</div>
    will be erased since you are doing this on row expand:
    Ext.get(expandRow).setHTML(html);
    You might need to restore that on row collapse. I am not sure what exactly you need.
  10. #10
    In what place do I need to put this code? I try to use Ext.onReady and Grid storeLoad and it doesn't call.
