Will LiveGrid be compatible with the new multisort features introduced in ExtJS 3.2 beta?

tested on ExtJS 3.1.1, livegrid r68 build.

I have also experienced the same problem. After inspecting the dom tree, I found the issue. The livegrid has a div element inside grid panel, and its height gives the scroll height to the vertical scrollbar. You will see something like

Code:

---

<div class="liveScroller" id="ext-gen44" style="top: 23px; height: 283px; ">
  <div style="height: 1973617px; "></div>
</div>

---

However, in IE8 (not sure about other IE versions), the maximum div height you can set is 1342177 pixels. I am not sure how to work around this problem other than changing the livegrid implementation.

that's quite depressing :D

The issue is that the calculations are based on the numbers of rows, where each row HAS to be the same height, i.e. it does not take into account variances in height. I did mention this to Mindpattern, and I hope he considers this to be top priority or else it will limit its applications and that would be a shame. His LiveGrid is really nice

Does anyone have a reliable solution for this issue, or this can't be fixed given the current implementation details?:-?

Are we likely to see any updates to this extension any time soon? I am starting to get worried about committing to using it in our application if its going to be left to die.

Don't worry, it's still very alive!

I am trying to copy cell content but the solution in the FAQ does not seem to be working.
Anyone knows how to do this?

Code:

---

templates : {
          cell : new Ext.Template(
                  '<td class="x-grid3-col x-grid3-cell x-grid3-td-{id} x-selectable {css}" style="{style}" tabIndex="0" {cellAttr}>',
                  '<div class="x-grid3-cell-inner x-grid3-col-{id}" {attr}>{value}</div>',
                  '</td>')
}

From the release announcement:

Ext.ux.Livegrid 0.4.1 is available!

The most notable change would be the treatment of the “liveScrollerInset”. In previous versions, this was a single “div” element, representing the scroll amount according to the number of records displayed by the Livegrid. This could lead to some issues in browsers which define a max height for HTML elements, making it impossible for users to scroll through all the records, as the max height of this inset would prevent scrolling beyond this point. We have now splitted this div into 3 single divs which resolves this issue.

There is also a change in Store.js - loading selections using the “selectionsProxy” would fail due to a call to a deprecated method which is no longer available since Ext 3.*.

Once 3.2. gets a stable candidate, Ext.ux.Livegrid will provide this feature, too.

This is fixed in 0.4.1
