我有一个超过20列的JQGrid。所以我保留前3列冷冻，网格没有分页。因此，根据要求，我们添加了主div的高度，以便用户可以向上/向下滚动。现在添加冻结列后，滚动将显示在网格的右侧，当鼠标滚动到任何未冻结的列时，它将起作用。但是当我尝试将鼠标滚动到冻结的列上时滚动不起作用。将获得任何线索/解决方案。

如果我正确理解了这个问题，那么你需要在冻结的列上使用鼠标滚轮。这样做你可以在调用setFrozenColumns之后在的地方添加以下代码：
$($grid[0].grid.fbDiv).bind("mousewheel DOMMouseScroll", function (e) {
$grid[0].grid.bDiv.scrollTop -= e.type === "mousewheel" ?
e.originalEvent.wheelDelta / 10 :
-e.originalEvent.detail * 6;
});
它应该有效，但我确信可以改进delta值的计算。我将考虑在setFrozenColumns的主代码中进行更改以自动执行相同的操作（在免费的jqGrid代码中）。

在您的页面上添加以下样式，这对我有用。
.frozen-bdiv {
pointer-events: none;
}
