The second issue is:
1.in IE9(or in IE11), when I typed in(or copied and pasted) the Chinese letters(“中文”)， they were shown correctly; and then I clicked some other cell, they changed into “ä¸æ”, and then I clicked the cell and the cell changed into edit mode, they changed into “中文” again. that was very strange.
2.in Chrome, it was different. when I typed in(or copied and pasted) the Chinese letters(“中文”)， they were shown correctly; and then I clicked some other cell, they changed into “ä¸æ”, and no matter how I clicked or did other things, they didn’t change back to “中文” again.
3.If the Chinese letters were set in server side(e.g gridCells.get(“B6”).putValue(“中文”);), they were properly shown. But if I tried to add some new letters, and when the cell losed focus, the text changed into strange letters again, as described in 1. and 2.
And by the way, I wrote some code like this:
GridValidation gridValidation = gridValidationCollection.Add();
ArrayList C11List = new ArrayList();
And when I selected an option(e.g “下拉列表选项2”), and I clicked some other cell, the text changed into strange letters too. I think it is the same issue as typing in(or coping-and-pasting) Chinese letters into a cell.
My OS is Windows 7, Simplified Chinese version, maybe it is different from the one you used to test, I think.
I hope what I found be of any help to you, thanks again.
