    {

                SqlCommand comm =new SqlCommand();
                comm.CommandText = "delete from tbluser where id=@id";
                comm.Connection = conn;

推荐答案

看看你在做什么.我想你想要的是这样的:

Look at what you''re doing. What I think you want is this:

CheckBox chk = row.FindControl("chkdelete") As CheckBox;
if (chk != null)
{
    if (chk.Checked)
    { 
        // do something
    }
}

在 ^ ].

字符串不包含选中的属性.您必须在asp复选框控件中强制转换网格视图复选框

string does not contains checked property. you have to cast grid view checkbox in asp checkbox control

CheckBox  chk = ((CheckBox)(row.FindControl("chkdelete")));
if (chk.Checked)
{
      ....
}
