[CLOSED] Question on grid summary with locking

Hi, I used to get grid summary data from grid.features, but after add locking columns, the grid.features = null and I need to find features from grid.lockgrid.features. Is there a common method that can return me grid features ? I am confused on when/how I should deal with the lockgrid.
I tired to disable/enable grouping with lock several times, the display starts messed up. I may create separated ticket for this, for now, I need to understand the lock grid.
Thanks

Hi @susanz,

Internally, a locking grid consists of two GridPanels - locked and normal. In this case a GridPanel reference becomes a wrapper from two GridPanels.
Also there are two instances of a Summary feature - one goes to a locked GridPanel and another - to a normal one.

These code snippets demonstrate how you could handle it.

Code:

---

var getSummaryFeature = function (grid) {
    var summaryFeature;

    Ext.Array.each(grid.features, function (feature) {
        if (feature.ftype === "summary") {
            summaryFeature = feature;
            return false; // Stops "each" iterating
        }
    });

    return summaryFeature;
};

---

Code:

---

if (grid.lockedGrid) {   
    // You are dealing with a locking grid   
    var lockedSummary = getSummaryFeature(grid.lockedGrid),       
        normalSummary = getSummaryFeature(grid.normalGrid);

    // Do the required with both the summary features
} else {   
    // You are dealing with a regular grid   
    var summary = getSummaryFeature(grid);

    // Do the required with the only summary feature
}

---

Got it, thanks Daniil, it works now.
