从GridView中怎么取出<asp:TemplateField> 中CheckBox的值
前台是这样的：
<asp:GridView ID="ListGrid" runat="server" AllowPaging="True" BackColor="White" 
                    BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="2px"
                    CellPadding="2" Height="12px" PageSize="6" Width="100%" CellSpacing="1"
                    OnPageIndexChanging="ListGrid_PageIndexChanging">
                    <Columns>
                        <asp:TemplateField HeaderText="ROLE_FLAG">
                            <ItemTemplate>
                                <asp:CheckBox ID="chkSelect" runat="server" Checked='<%# ChangeValue((String) Eval("ROLE_FLAG")) %>' />
                            </ItemTemplate>
                        </asp:TemplateField>
                    </Columns>
                </asp:GridView>
在.cs文件里，怎么取出ListGrid的CheckBox的值，我只想判断这个CheckBox是否被选中，谢谢了

Answer 1

楼上说的没错，我这有个小Demo，自己看下，很简单
for (int i = 0; i < GridViewPC.Rows.Count; i++)
        {
            GridViewRow curRow = GridViewPC.Rows[i];
            CheckBox cbx = (CheckBox)GridViewPC.Rows[i].FindControl("checkBoxSingle");
            CheckBox cbxHeader = (CheckBox)GridViewPC.HeaderRow.FindControl("CheckAll");
            int id = Convert.ToInt32(((HiddenField)curRow.FindControl("hdID")).Value);
            if (cbx.Checked == true)
            {
                list.Add(id);
                checkedSign = true;
            }
        }

Answer 2

foreach(GridViewRow gvr in ListGrid.Rows)
{
    CheckBox cb = gvr.Columns[0].FindControl("chkSelect");
    if(cb != null && cb.Checked)
    {
        //do something
    }
}
