          {
              SqlCommand sqlCmd = sqlConn.CreateCommand();

              //using sys.tables to call all table in database
              sqlCmd.CommandText = ("Select * From sys.tables");
              sqlConn.Open();
              SqlDataReader sqlDR = sqlCmd.ExecuteReader();
              while (sqlDR.Read())
              {
                  tablesCombobox.Items.Add((string)sqlDR[0]);
              }
              sqlDR.Dispose();
              sqlCmd.Dispose();

              for(int index = 0; index <= tablesCombobox.Selectedindex
              {//What code  i need to put in here to populate the gridview
               //which selected from combobox

Not clear what "ComboBox". There are different types under this name. Please tag your UI library and/or application type: WPF? Forms? Silverlight? ASP.NET?

--SA
P.S.: Yes, I can guess but I don't want. The question should be correctly put.

Try this code------------

private void DisplayTableData_Click(object sender, EventArgs e)
{
        SqlConnection con = new SqlConnection();
         Try
        {
          if(!string.isNullOrEmpty(cbTable.SelectedText))
            {
                    con.ConnectionString="Database ConnectionString";
                    SqlCommand sqlCmd = new SqlCommand("Select * From " + cbTable.SelectedText, sqlCon);
                    SqlDataAdapter da = new SqlDataAdapter();
                    da.SelectCommand=cmd;
                    DataTable dt = new DataTable();
                    da.Fill(dt);
                   dgvTableData.DataSource = dt.DefaultView;
            }
            else
             {
                    MessageBox.Show("No Table Selected...");
             }
         }
        Catch(Exception ex)
        {
          MessageBox.Show(ex.Message);
        }         
}

C#

private void viewTableButton_Click(object sender, EventArgs e)
 {
     using (SqlConnection sqlConn = new SqlConnection("Data Source=;Initial Catalog=" + "Integrated Security=SSPI"))
     {
           SqlCommand sqlCmd = sqlConn.CreateCommand();
 
           //using sys.tables to call all table in database
           sqlCmd.CommandText = ("Select * From sys.tables");
           sqlConn.Open();
           SqlDataReader sqlDR = sqlCmd.ExecuteReader();
           while (sqlDR.Read())
           {
               tablesCombobox.Items.Add((string)sqlDR[0]);
           }
           sqlDR.Dispose();
           sqlCmd.Dispose();
                
           //Try This
           if (comboBox1.SelectedIndex != -1)
           {
               sqlCmd.CommandText = ("Select * From "+ comboBox1.SelectedText);
               SqlDataAdapter da = new SqlDataAdapter(sqlCmd);
               DataSet ds = new DataSet();
               da.Fill(ds);
               datagridview1.DataSource = ds.Tables[0];
           }
     }
}

You need to take a datagidview say datagridview1 and
apply the following

1)generate the combobox_selectedindexchange event and write the following code

C#

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {


SqlConnection sqlConn = new SqlConnection("Data Source=;Initial Catalog=" + "Integrated Security=SSPI");

SqlCommand sqlCmd = sqlConn.CreateCommand();
 
               
                sqlCmd.CommandText = ("Select * From "+ comboBox1.SelectedText);
SqlDataAdapter da=new SqlDataAdapter(sqlCmd);
DataSet ds=new DataSet();
da.Fill(ds);

datagridview1.DataSource=ds.Tables[0];

        }
