问题描述

我有两个页面,一个是管理,另一个是教师。管理员分配受到教师。教师只只需要选择需要有时间。我的问题是,我不希望为残疾人复选框执行更新查询。我曾尝试低于code,但它更新为残疾复选框了。

 使用(SqlConnection的CON2 =新的SqlConnection(ConfigurationManager.ConnectionStrings
    [的ConnectionString]。的ConnectionString))
    {
    的foreach(在Gv1.Rows GridViewRow R){
     如果((((

解决方案

根据您的code如果复选框被禁止,则执行一个查询,如果启用复选框,再执行一次查询

 如果(aa.Enabled == FALSE)
{}
其他{}

如果您不希望禁用的复选框去掉执行下面的部分。

 如果(aa.Enabled == FALSE)
{}

I have two pages, one is admin and another one is faculty. Admin allocates subject to faculty. Faculty only want to select there required hours only. My issue is that I don't want to perform update query for disabled check box. I have tried the below code, but it is updating for disabled check box too.

  using (SqlConnection con2 = new SqlConnection(ConfigurationManager.ConnectionStrings
    ["ConnectionString"].ConnectionString))
    {
    foreach (GridViewRow r in Gv1.Rows){
     if  ((((

解决方案

According to your code if check box is disabled you perform one query and if check box enabled you perform another query

if (aa.Enabled==false)
{

}
else{

}

if you don't want to perform on disabled check boxes remove below part

if (aa.Enabled==false)
{

}
