新手求教，子窗口获得父窗口数据有关问题

新手求教，子窗口获得父窗口数据问题
因工作原因，小弟第一次学做网页，效果是查询到数据后进行修改的功能
用showModalDialog弹出修改子窗口，界面是一竖排的TextBox对应父窗口GridView的一行
想要弹出是对其需要的修改每个TextBox默认显示出GridView的数据
对于web还处于新手学习阶段，很多基础的知识都不清楚，只能摸索着学习了，
该如何实现呢
附上GridView的创建代码，是不是可以按照newrow.Cell[i]和tcRow[j]进行对应啊？

C# code

protected void GridView1_RowCreated( object sender , GridViewRowEventArgs e )    {        TableCellCollection tcRow = e.Row.Cells;        switch(e.Row.RowType)        {            case DataControlRowType.Header:                GridViewRow newrow=new GridViewRow(0,0, DataControlRowType.Header,DataControlRowState.Normal);                newrow.Visible=true;                for(int i=0;i<tcRow.Count;i++)                {                    TableCell tc=new TableCell();                    tc.Text=tcRow[i].Text;                    tc.VerticalAlign=VerticalAlign.Middle;                    tc.HorizontalAlign=HorizontalAlign.Center;                    newrow.Cells.Add(tc);                }                newrow.Cells[0].RowSpan=2;                newrow.Cells[1].RowSpan=2;                newrow.Cells[2].RowSpan=2;                newrow.Cells[3].RowSpan=2;                newrow.Cells[4].RowSpan=2;                newrow.Cells[5].ColumnSpan=2;                newrow.Cells.RemoveAt(6);                newrow.Cells[6].RowSpan=2;                newrow.Cells[7].ColumnSpan=2;                newrow.Cells.RemoveAt(8);                newrow.Cells[8].ColumnSpan=2;                newrow.Cells.RemoveAt(9);                newrow.Cells[9].ColumnSpan=2;                newrow.Cells.RemoveAt(10);                newrow.Cells[10].ColumnSpan=2;                newrow.Cells.RemoveAt(11);                newrow.Cells[11].RowSpan=2;                newrow.Cells[12].RowSpan=2;                tcRow[0].Text="Min";                tcRow[1].Text="Max";                tcRow[2].Text="Min";                tcRow[3].Text="Max";                tcRow[4].Text="Min";                tcRow[5].Text="Max";                tcRow[6].Text="Min";                tcRow[7].Text="Max";                tcRow[8].Text="Min";                tcRow[9].Text="Max";                for ( ; tcRow.Count > 10; )                {                    tcRow.RemoveAt( 10 );                }                GridView1.Controls[0].Controls.AddAt(0,newrow);                break;                            case DataControlRowType.DataRow:                break;        }}
