怎样在自定义控件中实现DataSource属性？

[anbeel]

因在控件中无法引用System.Data，那么

DataTable这种结构的数据怎么传入呢？

抱歉，你的sample我没有弄明白，你是不是指的用get, set返回值?

[伪装绅士]

哦,关注.

[心雨楼]

用枚举

>>>因在控件中无法引用System.Data

why not? did you add a reference to System.Data.dll in Solution Explorer?

[saucer]

here is a code example from the book by Nikhil Kothari


private object _dataSource;


[
Bindable(true),
Category("Data"),
DefaultValue(null),
Description("The data source"),
DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)
]
public virtual object DataSource {
get {
return _dataSource;
}
set {
if ((value == null) || (value is IListSource) || (value is IEnumerable)) {
_dataSource = value;
}
else {
throw new ArgumentException();
}
}
}
