dataGridView1_SelectionChanged事件有问题 [英] probleme with dataGridView1_SelectionChanged event

问题描述

大家好，

这是我的第一个问题，请问如果我有语法错误
我对此事件有疑问，有时不会发生此事件，例如我为按钮编写了以下行代码:

Hi guys ,

This is my first question, excuse me if i have grammatical error
I have a problem with this event , sometimes this event doesn''t occur , example i write this line code for a button:

dataGridView1.Rows[min_index].Selected = true;
dataGridView1.FirstDisplayedScrollingRowIndex = min_index;

选择min_index行，但selectionchanged 事件不起作用，有时搜索结果有一个结果，此事件不再发生

感谢

min_index row be selected but selectionchanged event doesn''t work and sometimes that search result has one result this event doesn''t occur again

thanks

推荐答案

是，谢谢您的回答
当使用鼠标笔划选择时，此事件正常工作，但是当我们想跳到特殊行时不起作用，有时在搜索结果中会发生，有时却不会发生

这是我在selectionchange事件中的代码

yes , thank you for answer
this event work properly when with mouse chenge selection but when we want jump to special row it doesn''t work , sometimes in search result it happens andsometimes itsn''t happen

this is my code in selectionchange event

try
            {
                stu_id = Convert.ToInt64(dataGridView1.CurrentRow.Cells[13].Value);
                schoolin_id = Convert.ToInt64(dataGridView1.CurrentRow.Cells[14].Value);
                Class = Convert.ToInt32(dataGridView1.CurrentRow.Cells[15].Value);
                IList<students> s = new List<students>();
                s = D_Students.Search_stu_id(stu_id);
                txt_name.Text = s[0].NAME;
                txt_family.Text = s[0].FAMILY;
                txt_f_name.Text = s[0].FATHER_NAME;
                IList<schooling_sign> sd = new List<schooling_sign>();
                sd = D_Schooling_Sign.Select_Year(schoolin_id);
                txt_schooling.Text = sd[0].YEAR;
                txt_class.Text = class_schooling.number_to_schooling(Class);
                button2.Enabled = true;
            }
            catch (Exception) { }


</schooling_sign></schooling_sign></students></students>

第3行表示排除所选行而不是当前所选行
谢谢
