单击编辑按钮后，如何将焦点设置到 datagridview 行中的特定控件？当网格绑定时，我可以为新行执行此操作，但不能为现有行执行此操作。该控件似乎还不存在。

'这不起作用（现有行）

Protected Sub gvDays_RowEditing(ByVal sender As Object, ByVal e As GridViewEditEventArgs) Handles gvDays.RowEditing
        Try
            gvDays.EditIndex = e.NewEditIndex
            gvDays.Rows(e.NewEditIndex).FindControl("txtDayText").Focus()
        Catch ex As Exception
            Helper.WriteException(ex)
        End Try
    End Sub

'这确实适用于新绑定的行

Private Sub gvDays_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvDays.RowDataBound
        If e.Row.RowState = DataControlRowState.Edit Then
            e.Row.Cells(3).Controls(0).Focus()
        End If
    End Sub

gvDays_RowDataBound应该可以工作，问题是您正在e.Row.RowState使用 = 运算符，但RowState它是一个位标志

尝试这个

Private Sub gvDays_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvDays.RowDataBound
        If (e.Row.RowState And DataControlRowState.Edit) = DataControlRowState.Edit Then
            e.Row.Cells(3).Controls(0).Focus()
        End If
End Sub
