问题描述
大家好，
我有一个webform包含gridview1(dgvParent)内的gridview2(dgvChild)，
在gridview1(dgvParent)列中，例如CustID，客户名称，地址，联系人，
展开(模板字段(项目模板)中的按钮)，客户订单明细(Gridview 2nd在这里)现在我想要在gridview1中按Expand按钮的同时，
gridview2(客户订单明细)记录应与行中的展开按钮相对应显示.展开后，该特定按钮应变为折叠，然后
将特定的按钮更改折叠成expand.
我正在寻找的主要概念，如何在按扩展按钮的同时显示记录(在dgvChild中).任何建议都应先感谢您.获取代码要好得多.
提醒两个dgv从不同的不同表中填充，但也要提醒第二个表中的dgvParent CustId.给我最简单的建议.
在此先感谢........
我的代码如下所示...
Hi All,
I have a webform contain gridview2(dgvChild) inside gridview1(dgvParent),
In gridview1(dgvParent) Columns like CustID,Customer Name,Address,Contact,
Expand(Button in Template field(Item Template)),Customer order details(Gridview 2nd is here) Now i want that while pressing Expand button in gridview1,
gridview2(Customer order details) record should display correponding to expand button in the rows. After expand that particular button should change into collapse and after
collapse that particular button change into expand.
Main concept i am looking for, how to show records(In dgvChild) while pressing expand button. Any suggestion appreciate thanks in advance.Getting code is much better.
Reminder both dgv filled from different different table but dgvParent CustId in 2nd table also. provide me easiest suggestion.
Thanks in Advance........

dA.Fill(ds);
dgvParent.DataSource = ds.Tables[0].DefaultView;
dgvParent.DataBind();
con.Close();
BindGridChild1();
}
private void BindGridChild1()
{
SqlConnection con = new SqlConnection(@"server=ITP4\SQLEXPRESS;database=Namit1;UId=sa;Pwd=pass");
con.Open();
for (int j = 0; j < dgvParent.Rows.Count; j++)
{
GridView dgv = (GridView)dgvParent.Rows[j].Cells[4].FindControl("dgvChild");
string ABCD = dgvParent.Rows[j].Cells[0].Text;
SqlCommand cmd = new SqlCommand("Select * from Order1 where CustID='" + ABCD + "'", con);
SqlDataAdapter dA = new SqlDataAdapter();
dA.SelectCommand = cmd;
DataSet ds = new DataSet();
dA.Fill(ds);
dgv.DataSource = ds.Tables[0].DefaultView;
dgv.DataBind();
}
con.Close();
