<asp:GridView ID="GvNewsInfo" runat="server" AutoGenerateColumns="False" DataKeyNames="JobID"            EmptyDataText="当前没有任何招聘信息!" Width="100%"  AllowPaging="True"  EnableModelValidation="True">            <Columns>                <asp:TemplateField HeaderText="选择">                    <ItemTemplate>                        <asp:CheckBox ID="ChkItem" runat="server" />                    </ItemTemplate>                    <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="100px" />                </asp:TemplateField>                <asp:BoundField DataField="JobID" HeaderText="招聘ID" InsertVisible="False" ReadOnly="True"                    SortExpression="JobID" />             </Columns>            <HeaderStyle BackColor="#E9F3D6" ForeColor="#5C9948"></HeaderStyle>            <PagerStyle BackColor="#E9F3D6"></PagerStyle>        </asp:GridView>

有帮助的解答者分数不会少。急。急。急啊、、

foreach (GridViewRow gvr in GridView1.Rows)
{
System.Data.DataTable dt = new System.Data.DataTable();
System.Data.DataRow dr;
dt.Columns.Add(new System.Data.DataColumn("id", typeof(System.String)));
CheckBox ch = (CheckBox)gvr.FindControl("ChkItem");
if (ch.Checked)
{
dr = dt.NewRow();
dr[0] = GridView1.DataKeys[gvr.DataItemIndex].Value.ToString(); 
dt.Rows.Add(dr);
}

这句也放到foreach外面来

给个小例子。。

C# code

        foreach (GridViewRow row in GridView1.Rows)        {            bool postback = ((CheckBox)row.FindControl("CheckBox1")).AutoPostBack;            if (!postback)            {                ((CheckBox)row.FindControl("CheckBox1")).AutoPostBack = true;            }        }
[解决办法]
前台：
<input name="CheckBox" id="CheckBox" runat="server" type="checkbox" value='<%#Eval("UserID") %>' />
后台
public string Getid()
       {
           string streid = "";
           for (int i = 0; i < this.GvNewsInfo.Rows.Count; i++)　             //根据Repeater 控件的情况执行循环判断目标复选框是否被选中
           {
               HtmlInputCheckBox CB = (HtmlInputCheckBox)this.Repeater1.Items[i].FindControl("CheckBox");    //获取一个目标复选框情况
               if (CB.Checked == true)                       //判断该复选框是否被选中
               {
                   streid = streid + CB.Value + ","; //程序处理代码
               }
           }
           if (streid.Length > 0)
           {
               streid = streid.Remove(streid.Length - 1);
           }
           return streid;
       }
得到你选中的ID 以,分开的 数组
