组合框和值之间的GridViewDataComboBoxColumn距离

Question

我有一个DevExpress网格视图控件（ASP.Net），我的一个列是GridViewDataComboBoxColumn。下拉列表的数据源在后面的代码中设置，并且没有问题。我似乎唯一的问题是当你点击下拉列表时，组合框与值之间有很大的距离。

知道我在这里做错了吗？

Answer 1

问题在于我在父容器中使用的CSS类。有问题的元素是“Display：inline”属性：

#container

{     显示：内联;     padding-left：50px;     padding-right：80px; }

删除它解决了这个问题。不确定我理解为什么这是问题，但至少问题已经解决了。希望这有时可以帮助别人。
