As you had not mentioned earlier on which plaform you are working with. DataTable has a method that help you to reorder its column dummydt.Columns[0].SetOrdinal(1); // 0 is columnName/ColumnIndex // SetOrdinal is the position to be placed // change your index accordingly grdviw.DataSource = dummydt; grdviw.DataBind(); As your code will decrease your performance as you are binding your gridview under a loop its better to bind it outside it. Hope it helps

private void sortingData(List columname) { DataTable dtsorting = new DataTable(); dtsorting = (DataTable)ViewState[data]; DataTable dummydt = new DataTable(); string id = ViewState[DtValue].ToString(); string[] arr = id.Split(''); if (columname.Count > 0) { for (int i = 0; i { dummydt = dtsorting.DefaultView.ToTable(false columname.ToArray()); dummydt.Columns[0].SetOrdinal(i); grdviw.DataSource = dummydt; grdviw.DataBind(); } } else { grdviw.DataSource = null; grdviw.DataBind(); } Here i values is get from array. Array contains my checkbox Values

The code which was posted is for runtime itself. Paste the code after you done working with gridview2. It would be useful if you share some code.

If I understood your requirement properly are you asking to reorder the columns? This can be done like Gridview1.Columns [ columnName].DisplayIndex =1; // change the index as per your need.

Here is the solution DataTable contains rows DataTable dt = new DataTable(); dt.Columns.Add( number ); dt.Columns.Add( name ); dt.Columns.Add( city ); dt.Columns.Add( address ); dt.Columns.Add( country ); dt.Columns.Add( gender ); dt.Columns.Add( nation ); dt.Rows.Add( 1 ); GridView1.DataSource = dt; GridView1.DataBind(); On button click binding the 2nd gridview in a sequence var dt = (DataTable)GridView1.DataSource; string [] sequence = { name  address  city  number  country }; ; var newdr = dt.DefaultView.ToTable( false  sequence); for ( int i = 0; i { newdr.Columns[sequence[i]].SetOrdinal(i); } GridView2.DataSource = newdr; GridView2.DataBind(); Same has been attached. Hope this helps :)
