check what the string is in 'insrtQry' variable

there's some problem here foreach (DataGridViewCell cell in dataGridView1.Rows[rowIndex].Cells)

Hi mayuri,
use follwing code to get cell value

int cols = yourGridView.Rows[0].Cells.Count;
foreach (GridViewRow gr in yourGridView.Rows)
{
for (int i = 0; i < cols; i++)
{
//create your string here

}
}

update your Inser Function like..

 private void InsertInfo()
 {
 
 string connectionString = null;
 SqlConnection connection;
 SqlDataAdapter adapter = new SqlDataAdapter();
 
 connectionString = @"Data Source=HP\SQLEXPRESS;database=MK;Integrated Security=true";
 connection = new SqlConnection(connectionString);
 foreach (int rowIndex in lstNewRows)
 {
 

 string insrtQry = "insert into " + comboBox1.SelectedText + " values(";
 
int cols = yourGridView.Rows[0].Cells.Count;
 foreach (GridViewRow gr in yourGridView.Rows)
 {
     for (int i = 0; i < cols; i++)
     {
         insrtQry += "'" + gr.Cell[i].Text.ToString() + "',";
     }
 }

 
 insrtQry = insrtQry.TrimEnd(",".ToCharArray());
 
 insrtQry += ")";
 

 
 try
 {
 connection.Open();
 adapter.InsertCommand = new SqlCommand(insrtQry, connection);
 adapter.InsertCommand.ExecuteNonQuery();
 

 
 MessageBox.Show("Row inserted !! ");
 }
 catch (Exception ex)
 {
 MessageBox.Show(ex.ToString());
 }
 

 }
 }
