I suggest you buy a book and work through it so you know how to program instead of blindly copying code from various sites. Articles are great, but you should work through them so you understand the code. We can't help you, except to say that you've used the keyword 'unicode' and it's not supported. For more info, we need to see the code.

thanks for your suggestion. here is the code and try to help me. using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Data.OleDb; using System.Data.OracleClient; public partial class Default13 : System.Web.UI.Page { private void Createrow(Table childtable,int index) { GridViewRow row = new GridViewRow(-1, -1, DataControlRowType.DataRow, DataControlRowState.Normal); row.Cells.Add(createcolumn()); childtable.Rows.AddAt(index + 2, row); } private TableCell createcolumn() { TableCell tc = new TableCell(); tc.ColumnSpan = GridView1.Columns.Count; tc.Width = Unit.Percentage(100); DataSourceControl ds = createdatasource(); tc.Controls.Add(ds); tc.Controls.Add(createdetailsview(ds)); return tc; } private DataSourceControl createdatasource() { SqlDataSource ds = new SqlDataSource(); ds.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString2"].ConnectionString ; ds.SelectCommand = "SELECT DEPTNO, DNAME FROM DEPT1 where deptno=@deptno"; Parameter pc = new Parameter("deptno", TypeCode.String, GridView1.SelectedValue.ToString()); ds.SelectParameters.Add(pc); ds.ID = "SqlDataSource2"; return ds; } private static DetailsView createdetailsview(DataSourceControl ds) { DetailsView dv = new DetailsView(); dv.AutoGenerateRows = true; dv.DataSourceID = ds.ID; return dv; } protected void Page_Load(object sender, EventArgs e) { } protected void GridView1_PreRender(object sender, EventArgs e) { if (GridView1.SelectedRow!= null) { Table childtable = GridView1.SelectedRow.Parent as Table; if (childtable != null) Createrow(childtable, GridView1.SelectedIndex); } } protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { } }

Have you thought to set a breakpoint, so you can see what *line* is blowing up ?

i did that too but every line is executing very well. At the end of lasat curly brace its giving error. i thought there is no error in the program. but i think the error i am getting is general error due to some settings. if anyone aware of this type of error then they may solve.
