子GridView失去对按钮单击的关注 [英] Child gridview losing focus on button click

问题描述

我已经完成了以下方案，我有一个网格视图，该网格视图具有另一个网格视图作为该网格视图的Item模板.最初，我绑定了一个单选按钮和数据库中的必填字段.当用户选择单选按钮时，我会在另一个网格中显示相应的详细信息.此网格视图具有一些带有复选框的必填字段.当我选中一个复选框并单击网格视图外的按钮时，我无法执行所编写的要求

I have done a scenario as follows, I am having a grid view which is having another grid view as Item template of that grid view. Initially I binded a radio button and the required fields from the database. When ever user selects a radio button I will show the corresponding details in another gridi vew. This grid view has some necessary fields with check boxes. When I select a check box and click on a button out side the grid view I am unable to execute the required that was written

<asp:Panel CssClass="grid" ID="pnlCust" runat="server">
        <asp:GridView ID="gvCustomers" AutoGenerateColumns="False" DataKeyNames="EmpID" runat="server"

删除按钮的代码

Code for delete button

protected void btn_Click(object sender, EventArgs e)
    {
        foreach (GridViewRow gvRow1 in gvCustomers.Rows)
        {
            GridView gv = (GridView)gvRow1.FindControl("gvOrders");
            foreach (GridViewRow gvrow in gv.Rows)
            {
                CheckBox chkBoxChild = (CheckBox)gvrow.FindControl("chkBoxChild");
                if (chkBoxChild.Checked)
                {

                }
            }
        }
    }

Unable to execute my condition when I select a check box and running the code. Any help please. Also how can I work out Select All check box scenario in the child grid view.
