gridview复选框无法正常工作 [英] gridview checkbox not working

问题描述

当我再次创建新的Web表单时，代码工作正常。但当我添加其他代码的文件

上传它不再工作。似乎代码不起作用如果在网页表单中添加其他代码

???





for（int i = 0; i< GridView1.Rows.Count; i ++）

{

CheckBox chkDelete =（CheckBox）GridView1.Rows [i] .Cells [0] .FindControl（chkSelect）;

if（chkDelete！= null）

{



if（chkDelete.Checked）

{

strID = GridView1.Rows [i] .Cells [1] .Text;

idCollection。添加（strID）;

}

}

}

the code worked when i created a new web form again. but when i added other codes for file
uploading it doesnt work anymore. it seems that the code does not work if add other codes in
the web form ???


for (int i = 0; i < GridView1.Rows.Count; i++)
{
CheckBox chkDelete = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("chkSelect");
if (chkDelete != null)
{

if (chkDelete.Checked)
{
strID = GridView1.Rows[i].Cells[1].Text;
idCollection.Add(strID);
}
}
}

<Columns>
                       <asp:TemplateField>
                       <ItemTemplate>
              <asp:CheckBox ID="chkSelect" runat="server" />
             </ItemTemplate>

                       </asp:TemplateField>
                   </Columns>
