推荐答案

您可以通过设置一些属性并实现所使用控件的事件来做到这一点.例如，如果您使用的是文本框，则将其AutoPostBack属性设置为true，如

You can do this by setting some properties and implementing the events of the control you are using. For example, if you are using a textbox then set its AutoPostBack property to true as

AutoPostBack="true"

并将其onTextChanged事件实现为

and implement its onTextChanged event as

ontextchanged="txtTest_TextChanged"

protected void txtTest_TextChanged(object sender, EventArgs e)
    {
// Write your code to save values in database.
    }

或者，您也可以使用ajax并使用客户端onblur事件异步保存数据.

Alternatively you can also use ajax and save your data asynchronously using client side onblur event.

您需要使用单元格更改事件:MSDN:DataGrid.CurrentCellChanged事件 [ MSDN:UIElement.GotFocus事件 [^ ]

每次您在datagrid单元中更改值(或单元针对getFocus事件进行聚焦)时，都会引发此事件.您可以在此事件中保存数据.因此，无需单击保存就可以保存数据.

You need to use cell change event: MSDN: DataGrid.CurrentCellChanged Event[^]
You can also use, cell focus event: MSDN: UIElement.GotFocus Event[^]

Every time you change value in the datagrid cell (or cell is focused for gotFocus event), this event will be raised. You can save your data in this event. Thus, without clicking save you will be able to save data.
