我的问题是，课程可能会在不止一天内举行，但我的界面只允许一天。我应该使用AJAX处理这个问题，还是有其他办法吗？如果我应该使用ajax，我该怎么做？

我假设您正在寻找一种允许在“日”字段中进行多项选择的方法。如果是这样，你至少有几个选择：

1）使用CheckBoxList控件（http://msdn.microsoft.com/enIN/library/8bw4x4wa(v=vs.90).aspx）。 2）或者，如果房地产是个问题，请使用http://dropdowncheckboxes.codeplex.com/处的DropDownCheckBoxes控件

我如何在asp.net中执行以下操作？
