复选框的问题

Question

目前datagridview首列是复选框，我想根据选中的时候删除数据，怎么实现，
 是否被选中复选框就行

Answer 1

可以添加个button 
 我用伪语言给你写一哈哈
 你之前的sql-db 连接语句和 sqlcommand的设置我就不写了哈。
   在button里添加如下代码：
   if(checkbox.checked==true)
     { 
         string strsql=checkbox.text.tostring();
         ..... (执行sql语句)    
     }  希望对你有用！！

Answer 3

循环复选框？ 服务器控件直接取值就行了啊。要是HTML控件
function setCheck(obj) 
    {         
        var comxid=obj;            
        if(document.getElementById(comxid).checked==true) 
        {     
                document.getElementById("check_ids").value = document.getElementById("check_ids").value+obj+",";                
        } 
        else 
        { 
                document.getElementById("check_ids").value = document.getElementById("check_ids").value.replace(obj+",",'');                 
        } 
    }    <input type="checkbox" style="width:20px;height:20px;" id="ads" name="ads" value='阿萨德'  onclick="setCheck(this.value);"/>
        <input type="hidden" id="check_ids" name="check_ids"/>
String value= Request.Form["check_ids"].TrimEnd(',');

Answer 5

倒。写错了 
function setCheck(obj,value) 
    {         
        var comxid=obj;            
        if(document.getElementById(comxid).checked==true) 
        {     
                document.getElementById("check_ids").value = document.getElementById("check_ids").value+value+",";                
        } 
        else 
        { 
                document.getElementById("check_ids").value = document.getElementById("check_ids").value.replace(value+",",'');                 
        } 
    }    
<input type="checkbox" style="width:20px;height:20px;" id="ads" name="ads" value='阿萨德'  onclick="setCheck(this.name,this.value);"/>
        <input type="hidden" id="check_ids" name="check_ids"/>

Answer 6

 foreach (GridViewRow gvr in Gridno.Rows)
            {
                CheckBox cb = (CheckBox)Gridno.Rows[gvr.RowIndex].FindControl("CkItemno");//chItemno 是复选框的Id
                if (cb.Checked)
                {
                    if (TempPersonId.Trim() == "")
                        TempPersonId = Gridno.DataKeys[gvr.RowIndex].Value.ToString();
                    else
                    {
                        TempPersonId += "','" + Gridno.DataKeys[gvr.RowIndex].Value.ToString();
                    }
                }
            }
