急问一个gridview下的checkbox奇怪的问题

[xuhaoumsl]

我在gridview里面有一个checkbox, 我选中的时候为什么checked属性总是false

代码如下

<asp:CheckBox ID="ckAutoRenew" runat="server" />

在gridview的OnRowDataBound有如下代码

protected void gvPackage_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (gvPackage.Rows.Count > 0)
{
CheckBox ck = (CheckBox)e.Row.FindControl("ckAutoRenew");
if (ck != null)
{
OrderDataSet.SPGetAStorePlanDetailsRow aStorePlanRow = OrderDB.GetStorePlanDetailsByStorePlanID((int)gvPackage.DataKeys[e.Row.RowIndex].Values[0]);
if (aStorePlanRow.bRealTime)
{

if (!aStorePlanRow.IsvchOTRenewNull() && aStorePlanRow.vchOTRenew == "After Fulfill")
{
ck.Visible = true;
ck.Enabled = true;
}
else
{
ck.Visible = false;
ck.Enabled = false;
}
}
else
{
ck.Visible = false;
ck.Enabled = false;

}
}
}

}


最后当我点击button的时候 根据checkbox 是否选中 作如下事情

CheckBox ck=(CheckBox)gvPackage.Rows[iNumber[j]].FindControl("ckAutoRenew");
if (ck != null)
{
if (ck.Checked)
aOrderPlanRow.bCurrentMonthlyPlan = true;
else
aOrderPlanRow.bCurrentMonthlyPlan = false;

}
else
{

aOrderPlanRow.bCurrentMonthlyPlan = false;

}
control 找的也是对的 但是为什么选中后仍然ck.Checked=false? 奇怪 哪里不对呢 ?

逐句跟踪执行一下,看看哪步又把他设回去了.或者你没重新绑定gridview

[xuhaoumsl]

我看了阿 没有对ck操作的语句 重新绑定gridview?

[namhyuk]

我看不懂这里：gvPackage.Rows[iNumber[j]], 检查哪些行的CheckBox被选中应该是一行一行检查吧？

如：
foreach(GridViewRow row in gvPackage.Rows)
{
CheckBox cb = (CheckBox)row.FindControl("ckAutoRenew");
AOrderPlanRow aOrderPlanRow = ((DataRowView)row.DataItem).Row as AOrderPlanRow;
aOrderPlanRow.bCurrentMonthlyPlan = (cb != null & cb.Checked) ? true : false;
//...
}

页面加载有没有
if(!IsPostBack)
{}

我这个是RadioBotton的.你参照下,重写个看看.

  protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        int index = ((GridViewRow)((Button)e.CommandSource).NamingContainer).RowIndex;
        RadioButton RadioButton1 = GridView1.Rows[index].FindControl("RadioButton1") as RadioButton;

             if (RadioButton1.Checked)
                {
                   Name = RadioButton1.Text;
                }
           int id =int.Parse( GridView1.DataKeys[index].Value.ToString());

           
    }
