有谁是用gridview里的asp:CheckBoxField实现全选删除功能的？

Question

网上搜了下，基本都是这种实现的，
<asp:TemplateField>
 <ItemTemplate>
  <asp:CheckBox ID="cb" runat="server" />
 </ItemTemplate>
</asp:TemplateField>有谁能给个用<asp:CheckBoxField实现的代码？

Answer 1

不明白,asp:CheckBoxField 是只读,他不能人为都去选取,你如何控制

<asp:GridView   ID="GridView1"   runat="server"   Width="842px"   AllowPaging="True"   CellPadding="0"> 
                                                <Columns>

Answer 4

 string str = "";
 string[] ckb = null;
 if (Request.Form.Get("checkboxname") == null)
{
     return;
}
str = Request.Form.Get("checkboxname");
ckb = str.Split(new char[] { ',' });取选中的，数组结果

Answer 5

楼上几位有点答非所问，lz要CheckBoxField，你们不还是checkbox么

Answer 6

我可能没跟大家说清楚，网上找到的都是用模板列实现的
<asp:TemplateField> 
  <ItemTemplate> 
    ...... 
  </ItemTemplate> 
</asp:TemplateField>我想不用模板列实现，想用asp:CheckBoxField实现，如果真像cefriend说的那样asp:CheckBoxField是只读的，那可能就无法实现了

Answer 7

CheckBoxField 在浏览器里 还是 html的checkbox吧
