如何在datagridview windform C＃中获取自定义值 [英] How to get custom value in datagridview windform C#

问题描述

我在sql中有一个表

< br /> 
 Sl |等级|备注< br /> 
 1 | A | ggggggggggggggggggg< br /> 
 2 | B | ddddddddddddddddddddd< br /> 
 3 | C | dddddddddxxxxxxxxxx< br /> 
 4 | D | rrrrrrvvvvvvvvvvvvv< br /> 

现在我的问题是通过填写datagridview1文本框中的Sl来从sql表中检索成绩。



如果我在datagridview文本框列填充2（SL）

SL |等级|备注

2 | |



然后它应该从sqltable中检索它的等级

< br /> 
 Sl |等级|备注< br /> 
 2 | B | ddddddddddddddddddddddddddddddddddddddddddddddddddbdbd bd bb b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b />

I have one table in sql 



<br />
Sl | Grade | Remark  <br />
1  | A     | ggggggggggggggggggg<br />
2  | B     | ddddddddddddddddddd<br />
3  | C     | dddddddddxxxxxxxxxx<br />
4  | D     | rrrrrrvvvvvvvvvvvvv<br />




Now my question is to retrieve grade from sql table by filling Sl in datagridview1 textbox. 



if I fill 2 in datagridview textbox column (SL)

SL | Grade | Remark

2  |       |  



then It should retrieve its grade from sqltable 

<br />
Sl | Grade | Remark  <br />
2  | B     | ddddddddddddddddddd<br />
