推荐答案
RadComboBox comboBox = (RadComboBox)editItem[dtBoundColumn.ColumnName].Controls[0];
在上一行中，当网格行处于编辑模式时，您尝试访问放置在gridview行中的组合框控件.
如果您将组合框放在gridview中(父级->子级)，则要访问子级控件，您必须在行项中进行搜索，并且在搜索后必须将其强制转换为原始类型.
in the above line, you are trying to acces combobox control, placed inside your gridview row, while grid row is in edit mode.
if you put a combobox inside a gridview (parent -> child), to access the child controls you have to search them inside the row items, and you have to type cast it to original type after searching.
GridEditableItem editItem = e.Item as GridEditableItem;
是的，在编辑"模式下，editItem是行项目.
Yes, editItem is a row Item while in Edit mode.
