我正在构建应用程序，并且正在构建更新表单.
我在要更新的表格字段中放置了一些文本框.
我需要单击行时，文本框会从有序行的每个单元格中检索数据.

我写了这段代码

textBox7.Text = "";
//this is the code of mine it works only when i select a row from the datagridview i need it work when i select a cell in this row
string[] arr = new string[4];
int i = 0;
foreach (DataGridViewCell item in dataGridView2.SelectedCells)
{
    arr[i] = item.Value.ToString();
    i++;
}
textBox5.Text = arr[0].ToString();
textBox6.Text = arr[1].ToString();

Try following

foreach (DataGridViewCell item in dataGridView2.CurrentRow.Cells)
{
    arr[i] = item.Value.ToString();
    i++;
}

如果您尝试使用WinForms，请进一步阅读，否则请通知我:
无论您是需要在单元格单击(如代码注释中所述)还是在选定的行上执行此作业，您都有这些事件(RowEnter，CellEnter等).事件args(DataGridViewCellEventArgs)为您提供RowIndex和ColumnIndex，您可以使用它们来获取所需的内容.这很简单，不确定您会遇到什么.

If you are trying with WinForms then read further else let me know:
Whether you need to do this job on cell click (as mentioned in the code comments) or on the row select, you have events for these (RowEnter, CellEnter etc.). And the event args (DataGridViewCellEventArgs) provide you with RowIndex and ColumnIndex which you can use to get what you want. It''s pretty straight forward, not sure what you are stuck with.
