GridView 中 Checkbox取值问题，急，急，急

[benben_tong]

<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>

现在有这么一个GridView，现在我要将第一列复选框选中的值存到DataTable中。请问各位大侠，这个该如何实现啊？

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);
}
}

嗯，你这个方法是没问题的。现在的问题是，我获取不到被选中的值。
<table cellspacing="0" rules="all" border="1" id="GvNewsInfo" style="width:100%;border-collapse:collapse;">
<tr style="color:#5C9948;background-color:#E9F3D6;">

@Override
public void onCreate(Bundle savedInstanceState) {

[lisweden]

dt.Columns.Add(new System.Data.DataColumn("id", typeof(System.String)));
这句也放到foreach外面来

[相当之稳重]

给个小例子。。

        foreach (GridViewRow row in GridView1.Rows)
        {
            bool postback = ((CheckBox)row.FindControl("CheckBox1")).AutoPostBack;
            if (!postback)
            {
                ((CheckBox)row.FindControl("CheckBox1")).AutoPostBack = true;
            }
        }

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
