问题描述

我的Datagrid已绑定到数据表.但它显示了一个额外的列.我想删除该列.
当我尝试在数据表中获取datagrid的内容时，当我尝试将Datagrid的内容获取到数据表中时，出现无法将类型System.windows.Controls.Datagrid转换为System.Data.Datatable"的错误. br/>

正确的方法是什么?

我的代码:DataTable dataTable =(DataTable)dataGrid;

My Datagrid is bound to datatable. But it displays an extra column. I want to delete that column.
when i am trying to get the content of datagrid in datatable I am Getting an Error as "cannot convert type System.windows.Controls.Datagrid to System.Data.Datatable" when i try to get the content of Datagrid into a datatable.


What is the correct way to do it?

My Code: DataTable dataTable = (DataTable)dataGrid;

推荐答案

您发布的代码试图从DataGrid创建DataTable.除非您执行类似的操作
，否则这是不可能的

The code you posted is trying to create a DataTable from your DataGrid. This is not possible unless you do something like

DataTable dt = (DataTable)dataGrid.DataContext;

但即使如此，它仍无法正确计算.如果要从绑定的DataGrid中删除列，则需要从基础绑定源中删除该字段.

希望这对您有帮助

but even still this does not really compute properly. If you want to delete columns from a bound DataGrid then you need to delete the field from the underlying Binding Source.

Hope this helps

Thanx Wayne.但是你能告诉我如何从底层的绑定源中删除吗???

Thanx Wayne. But can u tell me how to delete from the underlying Binding Source????
