DataGridView.CellValueChanged没有在绑定的DataGridView上触发 [英] DataGridView.CellValueChanged not firing on bound DataGridView

问题描述

当我在DataGridView绑定到DataTable中以编程方式更改值时，相应的CellValueChanged事件不会触发DataGridView。当数据表填充数据时，我试图根据单元格值更改单元格的背景颜色，而不会遍历每一行并检查每个值。

When I change a value programatically in a DataTable that my DataGridView is bound to, the appropriate CellValueChanged event is not firing for the DataGridView. I'm trying to change a cell's background color based on cell value when the DataTable is filled with data without iterating through every row and checking each value.

推荐答案

您正在直接更改 DataTable ，并期望 DataGridView 的事件被触发？
我建议您以编程方式更改单元格值：

You are changing the DataTable directly and expect DataGridView's event to be fired? I suggest that you change the cell value programatically as:

DataGridView[ColumnIndex, RowIndex].Value = NewValue;

此外，您必须调用 DataGridView.CommitEdit（）将值提交到 DataTable 。这应该触发 CellValueChanged 事件。

Additionally you will have to Call DataGridView.CommitEdit() to commit the values to the DataTable. This should trigger the CellValueChanged event.
