控件数据绑定后从脚本赋值但是数据源没有更新

Question

winform控件，比如textbox，设置数据绑定，脚本 

edtCreateUser.DataBindings.Add("EditValue", datatable, "列名", true, DataSourceUpdateMode.OnPropertyChanged);

我这里用的devexpress的控件，原理应该是一样的。

绑定后，如果在界面输入数据，datatable中的数据会变化。但是如果在脚本中赋值，如 edtCreateUser.EditValue = "test"; datatable的值就不变化，在网上搜索很长时间也没有找到原因，请达人指点，谢谢！

Hi,

由于第三方控件超出了MSDN 论坛的支持范围，我建议你到相应的控件供应商的论坛去寻找解决方案。建议你到下面的网址去询问：

考虑不用DataTable,考虑用BindingSource 控件，BindingSource才是双向绑定的，内存中的值与界面上控件的值是双向绑定（同步），

BindingSource  bs=..

bs.DataSource=datatable;

edtCreateUser.DataBindings.Add("EditValue", bs, "列名", true, DataSourceUpdateMode.OnPropertyChanged);
