Sir, it is inserting perfectly in records Table....if records table reachs 200 records.
the last 50 records must be automatically inserted into new table(ArchievedTable)

So, in record table it will have 150 records and in Archieved Table it will have 50 Records.

Please can u show me how to do this ?

Use a stored proc/trigger(run the horses of u r mind somewhat) for this some code you may use like

SQL

declare @rec int
select @rec=count(*) from RecordsTable

if(@rec>200)
begin

select top 50 * from RecordsTable --declare a table variable for this
--Now use a loop / MERGE command(probably N/A in SQL 2005) to sync the tables
--using insert query

end

Try u can get it done!!

Best of luck

if there any field like id....which is sequentially increasing....or any autoid field in table like1,2,3,4... then do following.....
1.On insert coding check row count
2.If row count is 200.
3.Execute to command one is to transfer record from one table to secound which is selected by order by id asc
4.Delete from first table
5.Refresh gridview...rebind to database...

exa.....

//your insert coding is here

SQL

int RecordsCount = Gridview1.Rows.Count ;

if (RecordsCount == 200)
{
//execute folowing command
cmd=new SqlCommand("insert into ArchievedTable(col_a, col_b)
select top 50 col1, col2 from RecordsTable
order by id asc",con);
cmd1=new SqlCommand("DELETE FROM RecordsTable WHERE id IN (SELECT TOP 50 id FROM RecordsTable ORDER BY id asc)",con);
cmd.ExecuteScaler();
cmd1.ExecuteScaler();

//then call gridbinding code here i.e refresh grid
BindDataToGrid();
}

something like this....hope it will help....

C#

for (int i = 0; i < (GridView1.Rows.Count) - 50; i++)
       {
           // save routine for Table that contains first 150 records
           BindWebControls.SetDataTarget(cn, "insert into put values('" + GridView1.Rows[i].Cells[0].Text + "')", 1, Label1);
       }

       for ( int z =(GridView1.Rows.Count) - 50;  z < GridView1.Rows.Count; z++)
       {
           // save routine for Table that contains last 50 records
           BindWebControls.SetDataTarget(cn, "insert into put1 values('" + GridView1.Rows[z].Cells[0].Text + "')", 1, Label1);
       }
