如何从绑定的DataRow中确定DataGridViewRow(How to determine a DataGridViewRow from the DataRow it is bound to)

如何从绑定的DataRow中确定DataGridViewRow(How to determine a DataGridViewRow from the DataRow it is bound to)

我想在触发DataTable事件时更改DataGridViewRow的前景色（特别是DataColumnChangeEvent ）。 为此，我需要获取事件发生的行的关联DataGridViewRow 。

我有以下内容：

private void DataColumnChanged(object sender, DataColumnChangeEventArgs e) { DataColumn col = e.Column; DataRow row = e.Row; if (col != null && row != null) { if (col.ColumnName == "abc") { String str = col.ToString(); if (str == "1") { DataGridViewRow dgvr = <somehow get row's associated DataGridViewRow> ChangeRowForeColor(dgvr, "Purple"); } } }

以下问题是相反的方向（从DataGridViewRow获取DataRow ），所以我知道它至少可以找到一种方式，但我似乎无法找到有关反向问题的信息。

如何确定哪个DataRow绑定到DataGridViewRow

将非常感谢如何从DataRow确定DataGridViewRow示例代码。

I would like to change the forecolor of a DataGridViewRow when a DataTable event is fired (specifically the DataColumnChangeEvent). In order to do so I need to get the associated DataGridViewRow of the row the event occurred on.

I have the following:

private void DataColumnChanged(object sender, DataColumnChangeEventArgs e) { DataColumn col = e.Column; DataRow row = e.Row; if (col != null && row != null) { if (col.ColumnName == "abc") { String str = col.ToString(); if (str == "1") { DataGridViewRow dgvr = <somehow get row's associated DataGridViewRow> ChangeRowForeColor(dgvr, "Purple"); } } }

The following questions are the reverse direction (getting a DataRow from a DataGridViewRow), so I know that it can be found one way at least, but I can't seem to find info on the reverse problem.

Example code of how to determine a DataGridViewRow from a DataRow would be greatly appreciated.

最满意答案

在行的主键上调用dataView.Find 。

编辑 ：要查找DataRowView的DataGridViewRow ，请调用grid.Rows[dataView.IndexOf(drv)) 。

Call dataView.Find on the row's primary key.

EDIT: To find the DataGridViewRow for a DataRowView, call grid.Rows[dataView.IndexOf(drv)).
