Hello,
I thought that you want this type of code like here...

C#

SqlDataAdapter adp = new SqlDataAdapter("select * from tbl1", cn);
       DataSet ds = new DataSet();
       adp.Fill(ds);

       SqlDataAdapter adp1 = new SqlDataAdapter("select * from tbl2", cn);
       DataSet ds1 = new DataSet();
       adp1.Fill(ds1);

       if (ds.Tables[0].Rows[0][0].ToString()==ds1.Tables[0].Rows[0][0].ToString())
       {
           SqlCommand cmd = new SqlCommand("insert into tbl1 values('" + TextBox1.Text + "','" + TextBox2.Text + "','" + TextBox3.Text + "')", cn);
           cn.Open();
           cmd.ExecuteNonQuery();
           cn.Close();

           SqlCommand cmd1= new SqlCommand("insert into tbl2 values('" + TextBox1.Text + "','" + TextBox3.Text + "')", cn);
           cn.Open();
           cmd1.ExecuteNonQuery();
           cn.Close();
       }

Hello,

Just wanted to improve the above solution.

Instead of using this check

C#

if (ds.Tables[0].Rows[0][0].ToString()==ds1.Tables[0].Rows[0][0].ToString())
       {}

use

C#

string compare = ds1.Tables[0].Rows[0][0].ToString();
if(ds.Tables[0].DefaultView.RowFilter = "SNo ='"+compare+"'")
{}

Row filter will check the value in all the row, not only in row whoes index is provided (Rows[0][0])
